Blueberry breakfast cake is the kind of easy morning bake that feels special without a complicated recipe. Tender vanilla-lemon crumb, pockets of juicy blueberries, and a golden top make it perfect for weekend brunch, potlucks, or a make-ahead treat with coffee.
This blueberry breakfast cake recipe walks you through creaming, folding berries, and baking in a simple 9-inch pan so the cake rises evenly and the blueberries stay suspended.

Why This Recipe Works
Coating blueberries in flour before folding them into the batter helps prevent sinking and bleeding, so you get even berry distribution in every slice. Creaming butter and sugar properly aerates the batter for a light, tender crumb, while lemon zest adds brightness that balances the sweetness.
Unlike dense coffee cake, this version stays moist from milk in the batter and bakes in one pan with minimal cleanup. For another easy morning bake, see our easy zucchini bread recipe.
Ingredients
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 2 cups all-purpose flour
- 2 teaspoons baking powder
- 1/2 teaspoon kosher salt
- 1/2 cup whole milk
- Zest of 1 lemon
- 2 cups fresh blueberries
- 2 tablespoons all-purpose flour (for coating blueberries)
How to Make Blueberry Breakfast Cake
1. Preheat and prep the pan
Preheat the oven to 350°F (175°C). Grease a 9-inch square baking pan and optionally line with parchment for easy lifting. Bring eggs and butter to room temperature for smoother mixing.
2. Whisk the dry ingredients
In a medium bowl, whisk together flour, baking powder, and salt until evenly combined. Set aside—this helps the leavening distribute evenly through the batter.
3. Cream butter and sugar
In a large bowl, beat softened butter and granulated sugar with a hand mixer or stand mixer until light and fluffy, about 2 to 3 minutes. Scrape the bowl as needed so everything incorporates evenly.
4. Add eggs and vanilla
Beat in eggs one at a time, mixing well after each addition. Stir in vanilla extract until smooth. The mixture should look pale and slightly thickened.
5. Combine wet and dry ingredients
Gradually add the dry ingredients to the butter mixture, alternating with milk, beginning and ending with the flour mixture. Mix on low speed just until combined—do not overmix.
6. Fold in lemon zest and blueberries
Gently fold in lemon zest. Toss blueberries with 2 tablespoons flour in a small bowl, then carefully fold them into the batter so they stay evenly distributed without crushing.
7. Spread and bake
Spread the batter evenly into the prepared pan. Bake 40 to 45 minutes until the top is golden and a toothpick inserted in the center (avoiding a blueberry) comes out clean or with moist crumbs.
8. Cool and serve
Cool in the pan 10 minutes, then transfer to a wire rack to cool completely. Dust with powdered sugar, serve with whipped cream or yogurt, and enjoy with coffee or tea.
Tips for the Best Blueberry Breakfast Cake
- Use fresh blueberries when in season; frozen works if thawed, patted dry, and still tossed in flour.
- Room-temperature butter and eggs cream together more easily.
- Do not overmix after adding flour—stir just until combined.
- Check doneness with a toothpick in cake, not directly in a berry.
- Store covered at room temperature up to 2 days, or refrigerate up to 5 days.
Variations
- Lemon glaze: Whisk powdered sugar with lemon juice and drizzle over cooled cake.
- Mixed berries: Swap half the blueberries for raspberries or blackberries.
- Streusel top: Sprinkle brown sugar–butter crumble over batter before baking.
- Gluten-free: Use a 1:1 gluten-free baking flour blend; texture may be slightly denser.
Make-Ahead and Storage
Bake the cake a day ahead for easier slicing—flavors meld and the crumb sets beautifully overnight. Wrap tightly in plastic wrap or store in an airtight container. Reheat individual squares at 300°F for 8 to 10 minutes for a warm breakfast. The cake also freezes well: wrap slices in plastic and foil for up to 2 months.

FAQ
Can I use frozen blueberries?
Yes. Do not thaw them completely—use still-cold berries, pat off excess moisture, and toss with flour before folding in. Add a few extra minutes to bake time if needed.
Why did my blueberries sink to the bottom?
Berries sink when they are too wet or not coated in flour. Toss blueberries with 2 tablespoons flour and fold gently at the very end of mixing.
Is blueberry breakfast cake the same as coffee cake?
It is similar—both are tender, single-layer cakes—but this recipe is lighter on streusel and heavier on fresh fruit. You can add a streusel topping for a more classic coffee cake feel.
Can I bake this in a round pan?
Yes. A 9-inch round pan works with the same bake time. A 9×13 pan will produce a thinner cake—start checking at 30 minutes.
How do I know when the cake is done?
The top should be golden and spring back lightly when touched. A toothpick inserted in the center should come out clean or with a few moist crumbs, not wet batter.
Can I reduce the sugar?
You can reduce sugar by up to 1/4 cup, but texture and browning will change slightly. The lemon zest helps keep the cake tasting bright with less sugar.
What should I serve with blueberry breakfast cake?
Powdered sugar, whipped cream, vanilla yogurt, or a simple lemon glaze all work well. Pair with coffee, tea, or our raspberry sunrise smoothie for a full brunch spread.
