The Full Old-Fashioned Blueberry Cake Donuts Recipe
Ingredients
- 3 tablespoons unsalted butter, at room temperature
- 1 cup granulated sugar
- ½ teaspoon kosher salt
- 1 teaspoon vanilla extract
- 2 cups all-purpose flour
- 1 cup cake flour
- 1 teaspoon baking soda
- 2 teaspoons baking powder
- 2 large eggs, at room temperature
- 1 large egg yolk, at room temperature
- 1 cup buttermilk
- 2 cups frozen blueberries, thawed
Instructions
- Preheat the oven to 350ºF (175ºC). Grease donut pans with nonstick cooking spray and set aside. Tip: Ensure your donut pans are well-greased to prevent sticking.
- In a stand mixer bowl with the paddle attachment, cream together butter, sugar, salt, and vanilla until light and fluffy, about 3 minutes. Tip: Scraping down the sides of the bowl will ensure even mixing.
- In a separate bowl, whisk together all-purpose flour, cake flour, baking soda, and baking powder.
- Add the eggs and egg yolk to the mixer and cream until blended, about 1 minute. Tip: Make sure the eggs are at room temperature for better incorporation.
- Alternately add the flour mixture and buttermilk in 3 stages, mixing on medium-low and scraping down the sides between additions.
- Turn the mixer to low and gently stir in the blueberries until evenly incorporated and the batter turns a nice shade of blue/purple.
- Transfer the batter into a piping bag or a large ziplock bag with a corner cut off.
- Pipe the batter into each donut well until they are about ⅔ full (do not overfill). Tip: This will allow space for the donuts to rise without spilling over.
- Bake in the preheated oven for 18 to 20 minutes or until the donuts spring back when touched. Let them cool completely before glazing.
- In a large bowl, combine all the glaze ingredients and whisk together. Adjust the consistency by adding milk to thin or powdered sugar to thicken.
- Once the donuts are cool, dip each donut top and bottom into the glaze, shaking off excess, and place them on a wire rack over a baking sheet lined with parchment paper.
