Ingredients for Easy Blueberry Breakfast Cake

For the cake

• 2 cups all-purpose flour
• ¾ cup granulated sugar
• 2 teaspoons baking powder
• ½ teaspoon salt
• ½ cup unsalted butter, softened
• 2 large eggs, room temperature
• ½ cup sour cream, room temperature
• ¼ cup whole milk
• 2 teaspoons vanilla extract
• 1½ cups fresh blueberries
• 1 tablespoon all-purpose flour, for coating the blueberries
• 1 teaspoon lemon zest (optional)

For the topping

• 2 tablespoons coarse sugar or granulated sugar
• 1 tablespoon powdered sugar, for serving (optional)

Ingredient Notes

• Blueberries: Fresh blueberries give the cake a juicy texture and vibrant color. Frozen blueberries work too; add them directly from the freezer without thawing.
• All-purpose flour: Provides structure while keeping the cake tender. Measure it carefully to avoid a dry cake.
• Unsalted butter: Softened butter creates a rich flavor and helps produce a soft crumb.
• Sour cream: Adds moisture and a slight tang, balancing the sweetness of the cake.
• Milk: Helps create a smooth, spreadable batter and keeps the finished cake tender.
• Eggs: Room-temperature eggs combine more evenly with the butter and other ingredients.
• Vanilla extract: Adds warmth and enhances the flavor of the blueberries.
• Lemon zest: Optional, but a little fresh lemon zest brightens the blueberry flavor.

How to Make Easy Blueberry Breakfast Cake

Step 1: Prepare the baking pan

Preheat the oven to 350°F (175°C). Grease an 8 × 8-inch square baking pan and line it with parchment paper, leaving some overhang for easy removal.

Step 2: Cream the butter and sugar

In a large mixing bowl, beat the softened butter and granulated sugar with an electric mixer for about 2–3 minutes, until the mixture looks light and fluffy.

Step 3: Add the eggs and vanilla

Add the eggs one at a time, beating after each addition. Mix in the vanilla extract and optional lemon zest until evenly combined.

Step 4: Combine the dry and wet ingredients

In a separate bowl, whisk together the flour, baking powder, and salt. Add the dry ingredients to the butter mixture in batches, alternating with the sour cream and milk. Mix on low speed or fold gently until just combined.

Step 5: Fold in the blueberries

Toss the blueberries with 1 tablespoon of flour. Gently fold them into the batter using a spatula. Reserve a few berries to scatter over the top, if desired.

Step 6: Transfer to the pan

Spread the batter evenly in the prepared baking pan. Arrange the reserved blueberries on top and sprinkle with coarse sugar for a lightly crisp finish.

Step 7: Bake the cake

Bake for approximately 35–45 minutes, or until the top is golden and a toothpick inserted into the center comes out clean or with a few moist crumbs. If the top browns too quickly, loosely cover it with foil.

Step 8: Cool and serve

Let the cake cool in the pan for about 15 minutes. Lift it out using the parchment paper and cool further on a wire rack. Dust with powdered sugar before serving, if desired.

Tips for the Best Blueberry Breakfast Cake

• Use room-temperature ingredients: Softened butter, eggs, and sour cream combine more evenly and help create a consistent crumb.
• Measure flour accurately: Spoon flour into your measuring cup and level it off rather than packing it tightly.
• Avoid overmixing: Once the flour is incorporated, stop mixing. Overworking the batter can make the cake tough.
• Coat the blueberries: A light coating of flour may help distribute the berries throughout the cake.
• Don’t thaw frozen blueberries: Thawing can release excess moisture and discolor the batter.
• Check for doneness: Start checking at 35 minutes because oven temperatures and baking pans vary.
• Let the cake cool: Cooling helps the crumb set, making the cake easier to slice neatly.

Easy Blueberry Breakfast Cake Variations

1. Lemon Blueberry Breakfast Cake

Add 1 tablespoon of lemon zest to the batter and drizzle a simple lemon glaze over the cooled cake for a bright, citrusy flavor.

2. Blueberry Streusel Breakfast Cake

Prepare a simple streusel using flour, brown sugar, cold butter, and a pinch of cinnamon. Sprinkle it over the batter before baking for a crunchy topping.

3. Blueberry Almond Cake

Add ½ teaspoon of almond extract and sprinkle sliced almonds over the top before baking. The nutty flavor complements the blueberries.

4. Cinnamon Blueberry Cake

Add ½ teaspoon of ground cinnamon to the dry ingredients for a warm, comforting flavor.

5. Blueberry Cake with Cream Cheese Glaze

Whisk softened cream cheese with powdered sugar and a little milk until smooth. Drizzle the glaze over the completely cooled cake.

How to Store Blueberry Breakfast Cake

• Room temperature: Store the unglazed cake in an airtight container for up to 2 days in a cool environment.
• Refrigerator: Store the cake in an airtight container for up to 5 days. Refrigerate promptly if you add cream cheese glaze.
• Freezer: Wrap individual slices tightly and place them in a freezer-safe container for up to 2 months for best quality.
• Reheating: Warm individual slices briefly in the microwave until just warm, or use a 300°F oven for a few minutes.
• Make ahead: Bake the cake the day before serving and keep it covered. Add powdered sugar or glaze just before serving.

What to Serve with Blueberry Breakfast Cake

This cake is delicious on its own, but it also pairs well with several breakfast and brunch favorites.

• Scrambled eggs or an omelet
• Fresh strawberries and raspberries
• Greek yogurt with honey
• Crispy bacon or breakfast sausage
• A fresh fruit salad
• Hot coffee, cappuccino, or tea

Frequently Asked Questions

1. Can I use frozen blueberries for breakfast cake?

Yes. Frozen blueberries work well in this recipe. Add them straight from the freezer without thawing to help prevent excess moisture and streaks of purple in the batter.

2. Why is my blueberry breakfast cake dry?

Dry cake can result from too much flour, overbaking, or overmixing. Measure flour carefully, check the cake before the end of the suggested baking time, and mix the batter only until combined.

3. Can I make blueberry breakfast cake the night before?

Yes. Bake it the night before, let it cool completely, and store it in an airtight container. Dust with powdered sugar just before serving.

4. Can I use Greek yogurt instead of sour cream?

Yes. Plain, unsweetened, full-fat Greek yogurt is a suitable substitute for sour cream and provides a similar moisture and tanginess.

5. How do I stop blueberries from sinking?

Use a moderately thick batter, toss the blueberries lightly in flour, and fold them in gently. Reserving a few berries for the top can also help distribute their appearance throughout the cake.

6. Can I make this recipe in a round cake pan?

Yes. An 8- or 9-inch round cake pan can work, but the cake’s thickness and baking time may change. Check for doneness with a toothpick rather than relying only on the clock.

7. Is blueberry breakfast cake a dessert or a breakfast recipe?

It can be both. This version has a moderately sweet, buttery crumb that works well for breakfast, brunch, or an afternoon snack.
