Ingredients You’ll Need

Success in baking begins with superior ingredients. For these Old-Fashioned Blueberry Cake Donuts, I advocate for quality that you can taste and feel. Each component plays a critical role in achieving the desired texture and flavor profile.
- All-Purpose Flour: 3 cups (360g). Opt for an unbleached variety. Its moderate protein content provides the ideal structure for a tender, cake-like donut, preventing toughness while ensuring stability during frying.
- Granulated Sugar: 1/2 cup (100g). Pure cane sugar is preferred. It contributes sweetness, aids in browning, and helps keep the donuts moist.
- Baking Powder: 2 teaspoons. Essential for the cakey rise. Ensure it’s fresh; expired baking powder will lead to flat, dense donuts.
- Baking Soda: 1/2 teaspoon. Works synergistically with the acidity in the buttermilk to create a light, airy texture, further enhancing the cake-like quality of our Old-Fashioned Blueberry Cake Donuts.
- Salt: 1 teaspoon. Fine sea salt is my recommendation. It balances sweetness, enhances the blueberry flavor, and strengthens the gluten structure.
- Nutmeg: 1/2 teaspoon, freshly grated. This is non-negotiable for authentic Old-Fashioned Blueberry Cake Donuts. Its warm, subtle spice elevates the overall aroma and taste profile significantly.
- Buttermilk: 3/4 cup (180ml), cold. Its acidity reacts with the leavening agents, creating a tender crumb. The cold temperature is crucial for managing dough temperature.
- Unsalted Butter: 2 tablespoons (28g), melted and cooled. Butter provides richness, flavor, and contributes to the donut’s tender texture. Ensure it’s cooled to avoid cooking the eggs.
- Large Egg: 1, cold. A cold egg helps maintain dough temperature and provides structure and richness.
- Vanilla Extract: 1 teaspoon. Pure vanilla extract, not imitation, offers depth and rounds out the flavor profile of the Old-Fashioned Blueberry Cake Donuts.
- Fresh Blueberries: 1 cup (150g). Small, wild blueberries are ideal for even distribution and burst of flavor. If using frozen, do not thaw; toss directly into the flour to prevent bleeding.
- Vegetable Shortening or Canola Oil for Frying: 6-8 cups (approx. 1.5-2 liters). A high smoke point fat is critical for frying these Old-Fashioned Blueberry Cake Donuts without imparting off-flavors. Maintain a consistent temperature for best results.
Substitutions & Variations
Note: This video is for demonstration purposes and may use a slightly different method.
Innovation in the kitchen often involves thoughtful modifications. These substitutions allow you to adapt your Old-Fashioned Blueberry Cake Donuts to various dietary needs without sacrificing quality. For a whole-grain alternative, substitute up to half of the all-purpose flour with whole wheat pastry flour.
This maintains a delicate texture while increasing fiber content. Replace granulated sugar with a natural sugar substitute like erythritol or monk fruit blend for a lower-sugar option, adjusting quantities based on sweetness equivalence. For a dairy-free version, use a plant-based buttermilk substitute (almond milk with a tablespoon of lemon juice or apple cider vinegar, allowed to sit for 5 minutes) and a high-quality vegan butter.
Explore fruit variations by swapping blueberries for diced apples or raspberries, ensuring they are well-drained to prevent excess moisture. Always ensure precise measurements and temperature control when making these Old-Fashioned Blueberry Cake Donuts for consistent results.

Equipment You’ll Need
Precision equipment streamlines the process and ensures consistent results for these Old-Fashioned Blueberry Cake Donuts. I advocate for quality tools that enhance control and efficiency.
- Stand Mixer with Paddle Attachment: Essential for thoroughly mixing the dough without overworking it, which is critical for a tender donut crumb.
- Large Mixing Bowls: Several are needed for dry ingredients, wet ingredients, and dredging.
- Whisk and Spatula: For initial mixing and scraping down the bowl.
- Rolling Pin: A heavy, wooden rolling pin provides even pressure for consistent dough thickness.
- Donut Cutter: A 3-inch donut cutter with a 1-inch center hole is ideal. Consistency in size ensures even frying.
- Deep, Heavy-Bottomed Pot or Dutch Oven: Critical for maintaining stable oil temperatures during frying. Its thick walls distribute heat evenly.
- Deep-Fry Thermometer: Absolutely non-negotiable for precise temperature control. Fluctuations ruin texture and absorbency of the Old-Fashioned Blueberry Cake Donuts.
- Slotted Spoon or Spider Skimmer: For safely removing donuts from hot oil.
- Wire Rack with Baking Sheet: For draining excess oil and cooling, preventing sogginess.
- Kitchen Scale: For precise ingredient measurement, especially flour, ensuring recipe accuracy.
Step-by-Step Instructions

Creating perfect Old-Fashioned Blueberry Cake Donuts involves methodical steps and attention to detail. Follow these precise instructions for optimal results.
- Prepare Dry Ingredients: In a large mixing bowl, thoroughly whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, salt, and freshly grated nutmeg. Ensure all ingredients are evenly distributed to guarantee consistent leavening throughout your Old-Fashioned Blueberry Cake Donuts.
- Combine Wet Ingredients: In a separate medium bowl, whisk together the cold buttermilk, cooled melted butter, cold large egg, and pure vanilla extract until just combined. Using cold wet ingredients helps to control the dough temperature, which is crucial for fried goods.
- Form the Dough: Gradually add the wet ingredients to the dry ingredients. Mix on low speed with a stand mixer fitted with a paddle attachment, or use a sturdy spatula, until just combined. Do not overmix; a slightly shaggy dough is desirable. Overmixing develops gluten excessively, resulting in tough Old-Fashioned Blueberry Cake Donuts.
- Incorporate Blueberries: Gently fold in the fresh blueberries until they are evenly distributed throughout the dough. If using frozen blueberries, add them directly from the freezer without thawing, tossing them lightly in a tablespoon of flour first to prevent sinking.
- Chill the Dough: Cover the bowl with plastic wrap and refrigerate the dough for at least 1 hour, or up to 2 hours. Chilling firms the dough, making it easier to handle and preventing excessive oil absorption during frying. This step is vital for perfectly structured Old-Fashioned Blueberry Cake Donuts.
- Roll and Cut: On a lightly floured surface, gently roll out the chilled dough to a thickness of approximately 1/2 inch (1.25 cm). Use your 3-inch donut cutter to cut out donut shapes. Gather the scraps, re-roll gently, and cut out more donuts until all dough is used. Try to handle the dough as little as possible.
- Preheat Frying Oil: Pour vegetable shortening or canola oil into your deep, heavy-bottomed pot or Dutch oven, ensuring it is at least 3-4 inches deep. Attach a deep-fry thermometer to the side of the pot. Heat the oil slowly over medium heat to 350°F (175°C). Maintaining this precise temperature is key to perfectly cooked Old-Fashioned Blueberry Cake Donuts.
- Fry the Donuts: Carefully lower 2-3 Old-Fashioned Blueberry Cake Donuts into the hot oil, ensuring not to overcrowd the pot, which would drop the oil temperature. Fry for 1.5 to 2 minutes per side, or until they are golden brown and cooked through. The exact timing will depend on your oil temperature and donut thickness.
- Drain and Cool: Use a slotted spoon or spider skimmer to carefully remove the fried Old-Fashioned Blueberry Cake Donuts from the oil. Transfer them immediately to a wire rack placed over a baking sheet to drain any excess oil. This allows air circulation, preventing the bottoms from becoming soggy.
- Glaze (Optional): While the Old-Fashioned Blueberry Cake Donuts are still warm, you can dip them into your favorite glaze (a simple powdered sugar and milk glaze works wonderfully) or toss them in cinnamon sugar. Serve immediately for the best experience.

Pro Tips for Success
Achieving bakery-quality Old-Fashioned Blueberry Cake Donuts requires a technical understanding beyond just following steps. Here are Adam’s advanced insights:
- Temperature Control is Paramount: Maintain your frying oil at a consistent 350°F (175°C). If the oil is too cool, the donuts will absorb excessive oil, becoming greasy and heavy. If too hot, they will brown too quickly on the outside, remaining raw inside. Use a reliable thermometer and adjust heat frequently.
- Dough Hydration and Handling: The dough for these Old-Fashioned Blueberry Cake Donuts should be soft but manageable. Avoid adding too much extra flour when rolling, as this can dry out the dough. Handle the dough minimally to prevent over-developing gluten, which results in a tough donut.
- Blueberry Preparation: If using fresh blueberries, ensure they are thoroughly dry after washing to prevent adding excess moisture to the dough. For frozen blueberries, never thaw them. Toss them directly from the freezer into a small amount of flour before adding to the dough. This creates a protective coating, preventing them from bleeding color and sinking to the bottom.
- Donut Hole Management: Don’t discard the donut holes! Fry them alongside the main donuts. They cook faster and are an excellent indicator of your oil temperature and readiness before committing your larger donuts. They also make for delightful, bite-sized treats.
- Oil Quality: Use fresh, clean frying oil with a high smoke point. Used oil can impart off-flavors. Once done, allow the oil to cool completely, then strain it through a fine-mesh sieve or cheesecloth for potential reuse (though for optimal flavor, fresh oil is always best for these Old-Fashioned Blueberry Cake Donuts).
- Batch Frying: Fry your Old-Fashioned Blueberry Cake Donuts in small batches. Overcrowding the pot significantly lowers the oil temperature, leading to greasy, poorly cooked donuts. Give each donut ample space to cook evenly.
Storage & Reheating Tips
Old-Fashioned Blueberry Cake Donuts are best enjoyed fresh, warm from the fryer. However, proper storage can extend their deliciousness for a short period. Store leftover donuts in an airtight container at room temperature for up to 2 days.
To re-crisp and warm them, place them in a preheated oven at 300°F (150°C) for 5-7 minutes, or until just warmed through. Avoid microwaving, as this tends to make them rubbery and detracts from their cake-like texture. For optimal flavor and texture, I always recommend consuming these Old-Fashioned Blueberry Cake Donuts within 24 hours of preparation.
To further elevate your donut experience, consider the rich flavors of chocolate as an alternative. Our Homemade Chocolate Glazed Donuts are a decadent choice that perfectly complements the sweetness of blueberries.
What to Serve With This Recipe

While Old-Fashioned Blueberry Cake Donuts are a delightful indulgence on their own, pairing them with the right accompaniments can create a balanced and memorable culinary experience. For a refreshing contrast, consider serving them alongside a vibrant mixed berry salad, featuring fresh strawberries, raspberries, and blackberries, perhaps with a light lemon-mint dressing. A bowl of plain Greek yogurt, topped with a drizzle of honey and a sprinkle of toasted almonds, offers a protein-rich counterpoint.
For beverages, a robust cup of freshly brewed coffee, a calming herbal tea, or a tall glass of cold, unsweetened almond milk perfectly complements the rich flavors of these Old-Fashioned Blueberry Cake Donuts without overpowering them. Remember, balance is key to enhancing the overall enjoyment.
Frequently Asked Questions (FAQ)
Can I make Old-Fashioned Blueberry Cake Donuts ahead of time?
While these Old-Fashioned Blueberry Cake Donuts are undeniably best enjoyed fresh, you can prepare the dough a day in advance. After mixing and incorporating the blueberries, cover the dough tightly with plastic wrap and refrigerate it for up to 24 hours. When ready to fry, allow the dough to sit at room temperature for about 15-20 minutes to soften slightly before rolling and cutting. This partial preparation helps save time without significantly compromising the final texture.
What if I don’t have buttermilk for Old-Fashioned Blueberry Cake Donuts?
No buttermilk? No problem. You can easily make a homemade substitute.
For every cup of buttermilk required, simply add 1 tablespoon of white vinegar or lemon juice to a liquid measuring cup. Then, fill the rest of the cup with regular milk (dairy or non-dairy) and let it sit for 5-10 minutes until it slightly curdles. This acidity is crucial for reacting with the baking soda and achieving the desired tender crumb in your Old-Fashioned Blueberry Cake Donuts.
How do I prevent my Old-Fashioned Blueberry Cake Donuts from becoming greasy?
Greasy donuts are a common issue, almost always attributable to incorrect oil temperature. The key is to maintain a consistent oil temperature of 350°F (175°C) throughout the frying process. If the oil is too cool, the donuts will absorb too much fat.
If it’s too hot, the exterior will brown rapidly, leaving the interior undercooked and creating a dense texture that still feels greasy. Use a reliable deep-fry thermometer and adjust your heat source diligently. Also, avoid overcrowding the pot, as this drops the oil temperature significantly.
Old-Fashioned Blueberry Cake Donuts are a beloved treat known for their moist, cake-like texture and the burst of fresh blueberries in every bite. These delightful donuts can be traced back to classic recipes that celebrate the flavors of traditional baking, allowing you to savor a piece of culinary history through this donut.
