Ingredients You’ll Need
For the cake, gather:
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- ½ cup unsalted butter, softened
- ¾ cup granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- ½ cup buttermilk
- 2 cups fresh blueberries
- 1 tablespoon lemon zest
For the top, you can add a light sprinkle of granulated sugar before baking for a delicate crisp finish.
If using frozen blueberries, there’s generally no need to thaw them first. Add them directly to the batter to help prevent excess moisture from affecting the cake.
How to Make Buttermilk Blueberry Breakfast Cake
1. Prepare the Oven and Baking Pan
Preheat your oven to 350°F (175°C).
Grease a 9-inch square or round baking pan and line the bottom with parchment paper if desired.
The parchment makes it easier to lift the cake from the pan after baking.
2. Combine the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
Set the bowl aside.
Combining the dry ingredients separately helps distribute the leavening agents evenly throughout the cake.
3. Cream the Butter and Sugar
In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy.
This usually takes a few minutes with an electric hand mixer.
Properly creaming the butter and sugar helps create a lighter texture by incorporating air into the mixture.
4. Add the Egg and Vanilla
Add the egg and vanilla extract to the butter mixture.
Beat until well combined.
Add the lemon zest and mix briefly. The lemon zest isn’t overpowering, but it helps brighten the blueberry flavor and adds a wonderful fresh aroma.
5. Add the Buttermilk and Flour
Gradually add the dry ingredients to the butter mixture, alternating with the buttermilk.
Begin and finish with the dry ingredients.
Mix only until the batter comes together. Avoid overmixing because too much mixing can make the finished cake dense.
The batter will be fairly thick, which is exactly what you want for a blueberry breakfast cake.
6. Fold in the Blueberries
Gently fold the blueberries into the batter using a spatula.
Be careful not to crush the berries as you mix.
If using frozen blueberries, fold them in while still frozen. This helps prevent the berries from releasing excessive juice into the batter.
7. Bake the Cake
Transfer the batter to the prepared baking pan and spread it evenly.
If desired, sprinkle a little granulated sugar over the top.
Bake for approximately 40–50 minutes, or until the top is lightly golden and a toothpick inserted into the center comes out clean or with a few moist crumbs.
Because baking times vary between ovens and pan sizes, begin checking toward the earlier end of the baking range.
8. Cool and Serve
Allow the cake to cool in the pan for approximately 10–15 minutes.
Then transfer it to a cooling rack or serve directly from the baking dish.
For the best flavor, serve it slightly warm with a cup of coffee, tea, or cold milk.
Tips for the Best Blueberry Cake
Use room-temperature ingredients. Softened butter and a room-temperature egg help create a smoother batter.
Don’t overmix. Once the flour is incorporated, stop mixing. This keeps the cake soft and tender.
Coat very juicy berries lightly with flour. If your blueberries are particularly juicy, tossing them with a teaspoon of flour before folding them into the batter can help distribute them throughout the cake.
Use real buttermilk. Its acidity works with the baking soda and contributes to the cake’s characteristic tender texture.
Don’t overbake. Remove the cake once a toothpick comes out clean or with a few moist crumbs. Overbaking can dry out the edges.
Fresh or Frozen Blueberries?
Both work beautifully in this recipe.
Fresh blueberries provide a slightly firmer texture and bright fruit flavor. They’re especially delicious during blueberry season.
Frozen blueberries are convenient and allow you to make this cake year-round. Don’t thaw them before adding them to the batter. Thawed berries can release more liquid and may turn the batter purple.
Easy Variations
Lemon Blueberry Breakfast Cake
Increase the lemon flavor by adding additional lemon zest and finishing the cooled cake with a simple lemon glaze made from powdered sugar and fresh lemon juice.
Blueberry Streusel Cake
Before baking, sprinkle the batter with a simple mixture of flour, brown sugar, butter, and cinnamon.
The result is a crunchy, buttery topping that makes the cake feel extra special.
Mixed Berry Breakfast Cake
Replace some of the blueberries with raspberries, blackberries, or chopped strawberries.
This is a great way to use a variety of fresh berries.
Almond Blueberry Cake
Add a small amount of almond extract to the batter and sprinkle sliced almonds over the top before baking.
The nutty flavor pairs beautifully with blueberries.
Cinnamon Sugar Version
Add a teaspoon of cinnamon to the dry ingredients and finish the cake with cinnamon sugar before baking.
How to Serve Blueberry Breakfast Cake
This cake is delicious enough to enjoy by itself, but you can easily dress it up for brunch.
Try serving it with:
- Fresh blueberries
- Strawberries
- Whipped cream
- Greek yogurt
- Powdered sugar
- Lemon glaze
- Vanilla ice cream
- Maple syrup
For breakfast, a slice alongside Greek yogurt and fresh fruit makes a simple and satisfying meal.
For dessert, serve it slightly warm with a scoop of vanilla ice cream.
Can You Make This Cake Ahead?
Absolutely.
This is a great make-ahead breakfast recipe because it stays moist for several days when stored properly.
Bake it the evening before a brunch or family gathering, allow it to cool completely, and store it covered at room temperature if serving the next day.
For longer storage, refrigerate it in an airtight container.
How to Store Leftovers
Store leftover blueberry cake in an airtight container.
At room temperature, it can generally be enjoyed for approximately 2 days.
For longer storage, refrigerate it for up to 4–5 days.
Allow refrigerated slices to come toward room temperature before serving, or warm them briefly in the microwave.
Can You Freeze Blueberry Breakfast Cake?
Yes. This cake freezes very well.
Wrap individual slices tightly in plastic wrap and place them in a freezer-safe bag or container.
Freeze for up to 2–3 months for the best quality.
Thaw individual slices in the refrigerator or at room temperature before serving.
Frequently Asked Questions
Can I use frozen blueberries?
Yes. Frozen blueberries work very well. Add them directly to the batter without thawing.
What can I use instead of buttermilk?
If you don’t have buttermilk, you can make a simple substitute by combining milk with lemon juice or white vinegar and allowing it to sit for several minutes.
Why is my blueberry cake dense?
Overmixing the batter or using too much flour can make the cake dense. Mix just until the dry ingredients are incorporated and measure the flour carefully.
Can I use a different pan?
Yes. An 8- or 9-inch square pan, round cake pan, or similar baking dish can work. Keep in mind that changing the pan size will affect the baking time.
Can I add a glaze?
Absolutely. A simple lemon glaze made with powdered sugar and fresh lemon juice is especially delicious with blueberries.
