Ingredients

For this irresistible Blueberry Buttermilk Breakfast Cake, you’ll need:

• 2 cups (250g) all-purpose flour
• 1 tablespoon baking powder
• ½ teaspoon salt
• ½ cup (113g) unsalted butter, softened
• 1 cup (200g) granulated sugar
• 1 large egg, room temperature
• 1 teaspoon pure vanilla extract
• 1 cup (240ml) buttermilk, room temperature
• 2 cups (300g) fresh blueberries
• 2 tablespoons turbinado sugar for topping (optional)

The buttermilk is crucial for this recipe as it adds tanginess and reacts with the baking powder to create a tender crumb. If you don’t have buttermilk on hand, you can make a quick substitute by adding 1 tablespoon of white vinegar or lemon juice to 1 cup of milk and letting it sit for 5 minutes.

Fresh blueberries provide the best flavor and texture, but frozen blueberries can work in a pinch—just don’t thaw them before adding to the batter to prevent bleeding. The turbinado sugar adds a delightful crunch to the top, but regular granulated sugar works well too.

Pro Tips

Handling the Batter
When making Blueberry Buttermilk Breakfast Cake, resist the urge to overmix the batter. Mix just until the ingredients are combined—a few small lumps are perfectly fine. Overmixing activates the gluten in the flour, resulting in a tough, dense cake rather than the tender, moist texture we’re aiming for. Think of it as a gentle folding rather than vigorous beating once the dry ingredients join the wet.

Blueberry Distribution
To prevent blueberries from sinking to the bottom of your breakfast cake, toss them in 1-2 tablespoons of flour before folding them into the batter. This light coating helps them suspend throughout the cake as it bakes. Additionally, reserve about ¼ cup of berries to scatter on top of the batter right before baking for a beautiful presentation.

Temperature Matters
Ensure all refrigerated ingredients—especially the buttermilk and egg—are at room temperature before beginning. This creates a smooth, evenly mixed batter that bakes more uniformly. If you’re short on time, place the egg in warm water for 5 minutes and microwave the buttermilk in 10-second intervals until just room temperature, not hot. The softened butter should be cool to the touch but pliable enough to leave an indentation when pressed.

Instructions

Step 1: Prepare the Oven and Pan
Preheat your oven to 350°F (175°C). Prepare a 9-inch square baking pan by greasing it thoroughly with butter or non-stick spray, then line it with parchment paper, leaving some overhang for easy removal. This extra step ensures your Blueberry Buttermilk Breakfast Cake won’t stick to the pan.

Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, and salt. This even distribution of leavening agents ensures your cake rises uniformly. Set this mixture aside while you prepare the wet ingredients.

Step 3: Cream Butter and Sugar
In a large bowl, beat the softened butter and granulated sugar with an electric mixer until light and fluffy, about 3-4 minutes. Don’t rush this step—proper creaming incorporates air into the batter, creating that tender crumb we’re after. The mixture should noticeably change color to a pale yellow.

Step 4: Add Egg and Vanilla
Add the egg and vanilla extract to the butter mixture and beat until fully incorporated and smooth. Scrape down the sides of the bowl to ensure everything is evenly mixed.

Step 5: Alternate Dry Ingredients and Buttermilk
With the mixer on low speed, add the flour mixture and buttermilk alternately, beginning and ending with the flour (three additions of flour and two of buttermilk). Mix just until incorporated after each addition—this gentle approach prevents overmixing and keeps your breakfast cake tender.

Step 6: Fold in Blueberries
Gently fold in 1¾ cups of the blueberries using a rubber spatula. The folding motion preserves the air bubbles in your batter while minimizing berry breakage. Reserve the remaining berries for topping.

Step 7: Transfer and Top
Pour the batter into your prepared pan, smoothing the top with a spatula. Scatter the reserved blueberries over the surface and sprinkle with turbinado sugar for a delightful crunch.

Step 8: Bake to Perfection
Bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean with a few moist crumbs. The top should be golden brown and spring back slightly when touched.

Step 9: Cool and Serve
Allow your Blueberry Buttermilk Breakfast Cake to cool in the pan for 15 minutes before using the parchment overhang to lift it out. Let it cool on a wire rack for another 15 minutes before slicing—though it’s delicious warm, allowing some cooling time helps the cake set properly for clean slices.

Variations

Lemon Blueberry Buttermilk Cake
For a bright, citrusy twist on this Blueberry Buttermilk Breakfast Cake, add the zest of one lemon to the batter when creaming the butter and sugar. Replace ¼ cup of the buttermilk with fresh lemon juice to enhance the tangy flavor. After baking, drizzle the cake with a simple lemon glaze made from ½ cup powdered sugar mixed with 1-2 tablespoons of fresh lemon juice. This variation brings a refreshing zing that pairs beautifully with the sweet blueberries.

Mixed Berry Breakfast Cake
Create a colorful and flavorful variation by replacing half the blueberries with a mix of raspberries, blackberries, or chopped strawberries. The combination of different berries adds visual interest and complex berry flavors. Be gentle when folding in the more delicate berries to maintain their shape. This version makes a stunning centerpiece for summer brunches when berries are at their peak.

Whole Grain Breakfast Cake
For a healthier twist, substitute half the all-purpose flour with whole wheat pastry flour or white whole wheat flour. Add ¼ teaspoon of cinnamon and a pinch of nutmeg to complement the nuttier flavor of the whole grains. This adaptation adds fiber and nutrients while maintaining the tender texture of your breakfast cake. It’s perfect for those looking to incorporate more whole grains into their diet without sacrificing taste or texture.

Storage and Serving

This Blueberry Buttermilk Breakfast Cake stays fresh at room temperature for up to 2 days when stored in an airtight container. For longer storage, refrigerate for up to 5 days, though the texture is best within the first 3 days. You can also freeze individual slices or the entire cake for up to 3 months—wrap tightly in plastic wrap and then aluminum foil or place in a freezer-safe container. Thaw overnight in the refrigerator and warm slightly before serving.

For an elegant brunch presentation, serve slices with a dollop of lightly sweetened whipped cream and additional fresh berries on the side. The contrast between the warm cake and cool cream is delightful. For a more substantial breakfast, pair with Greek yogurt drizzled with honey and a sprinkle of toasted almonds for protein and crunch.

Transform this breakfast cake into a simple dessert by warming a slice and topping it with a small scoop of vanilla ice cream. The contrast between the warm cake and cold ice cream, along with the melding flavors of vanilla and blueberry, creates a memorable treat that’s sophisticated yet comforting.

FAQs

Can I use frozen blueberries instead of fresh?
Yes, you can use frozen blueberries in this Blueberry Buttermilk Breakfast Cake. Add them directly to the batter while still frozen—do not thaw first, as this prevents the color from bleeding throughout the batter. You may need to extend the baking time by 5-7 minutes when using frozen berries.

What can I substitute for buttermilk?
If you don’t have buttermilk, make a quick substitute by adding 1 tablespoon of white vinegar or lemon juice to 1 cup of milk. Let it stand for 5 minutes before using. Alternatively, plain yogurt thinned with a bit of milk works well too.

Why did my blueberries sink to the bottom?
Blueberries sink when they’re too heavy for the batter. Tossing them in 1-2 tablespoons of flour before adding them helps prevent sinking. Also, ensure your batter isn’t too thin—it should be thick enough to hold the berries in suspension.

Can this cake be made ahead of time?
Absolutely! You can make this breakfast cake the evening before and store it covered at room temperature. It’s also freezer-friendly—bake, cool completely, wrap well, and freeze for up to 3 months.

Is this cake too sweet for breakfast?
The sweetness level is moderate and appropriate for a breakfast treat. If you prefer a less sweet version, reduce the sugar to ¾ cup and omit the turbinado sugar topping. The natural sweetness of the blueberries still provides plenty of flavor.

Conclusion

This Blueberry Buttermilk Breakfast Cake is comfort food at its finest — a tender, moist treat that bridges the gap between breakfast and dessert with its perfect balance of sweetness and tang. It’s the kind of dish that transforms ordinary mornings into special occasions, yet remains simple enough to prepare on a whim.
