Ingredients notes for Buttermilk Blueberry Breakfast Bake
- All-purpose flour (2 cups): Keep some flour separate for coating the blueberries to prevent them from sinking in the batter.
- Fresh blueberries (2 cups): Adds a burst of juicy flavor and a beautiful color to the cake.
- Granulated sugar (1 cup + extra for topping): Sweetens the cake and gives the surface a delightful crunch when sprinkled on top before baking.
- Cultured buttermilk (1/2 cup): Contributes to the moist, tender texture of the cake.
- Unsalted butter (1/2 cup, 1 stick): Room temperature butter ensures a smooth, rich batter.
- Lemon zest (from 1 lemon): Provides a bright, citrus note that complements the blueberries.
- Large egg (1): At room temperature for a uniform batter.
- Baking powder (2 teaspoons): Helps the cake rise and become fluffy.

Variations and Substitutions
Whip up a delightful twist on the classic Buttermilk Blueberry Breakfast Bake with these easy variations and substitutions:
- Fruit Swaps: Not a blueberry fan or just looking for a change? Substitute blueberries with raspberries, chopped strawberries, or mixed berries for a vibrant twist.
- Dairy Options: If you’re out of buttermilk, make your own by mixing a tablespoon of vinegar or lemon juice with a cup of regular milk and letting it sit for a few minutes. For a lactose-free version, use almond, soy, or oat milk with the same acid addition.
- Flour Alternatives: Gluten-free? Replace regular flour with a gluten-free blend to cater to dietary needs without compromising texture.
- Sweetener Varieties: Swap out white sugar for honey, maple syrup, or even coconut sugar for a deeper flavor profile.

Ingredients
- 2 cups all-purpose flour divided
- 2 cups fresh blueberries
- 1 cup granulated sugar plus extra for topping
- 1/2 cup cultured buttermilk
- 1/2 cup unsalted butter 1 stick, room temperature
- Zest of 1 lemon
- 1 large egg room temperature
- 2 teaspoons baking powder
- 1 teaspoon vanilla extract
- 1 teaspoon kosher salt
Instructions
- Preheat your oven to 350º F and grease a square baking dish with butter or non-stick spray.
- In a medium bowl, whisk together 1 3/4 cups flour, baking powder, and salt.
- In a larger bowl, use an electric mixer to cream together the room temperature butter, sugar, and lemon zest until light and fluffy, about 3-5 minutes.
- Add the egg and vanilla extract to the butter mixture and mix until thoroughly combined.
- Alternately mix in the buttermilk and the flour mixture, starting and ending with the flour, to the butter mixture until just combined.
- Toss the blueberries with the remaining 1/4 cup of flour in a separate bowl; this helps prevent the berries from sinking to the bottom of the bake. Gently fold the blueberries into the batter.
- Pour the batter into the prepared baking dish. Sprinkle the top evenly with additional granulated sugar.
- Bake in the preheated oven for about 40 minutes, or until a toothpick inserted into the center comes out clean.
- Allow the cake to cool in the dish before serving. Enjoy your Buttermilk Blueberry Breakfast Bake!
