- 2 cups all-purpose flour: Provides structure and a tender crumb to the cake.
- 2 tsp baking powder: Ensures the cake rises beautifully and stays light.
- ½ tsp salt: Balances sweetness and enhances the blueberry flavor.
- ½ cup unsalted butter, softened: Adds richness and moisture for a melt-in-your-mouth texture.
- 1 cup granulated sugar: Sweetens the cake perfectly without overpowering the berries.
- 1 large egg: Binds the ingredients together and adds a touch of fluffiness.
- 1 tsp vanilla extract: Brings warm, aromatic depth to the batter.
- ½ cup buttermilk: Gives a subtle tanginess and keeps the cake moist and tender.

How to Make Buttermilk Blueberry Breakfast Cake Recipe
Step 1: Prepare Your Pan
Preheat your oven to 350°F (175°C) and grease and flour an 8-inch square baking dish, or line it with parchment paper. This step sets the stage for your cake to bake evenly and prevents sticking without fuss.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, and salt. This ensures the leavening and seasoning are evenly distributed, which helps the cake rise consistently and taste perfectly balanced.
Step 3: Cream Butter and Sugar
In a large bowl, beat the softened butter and granulated sugar until the mixture is light and fluffy. This aeration creates the tender texture and delicate crumb so characteristic of this cake.
Step 4: Add Egg and Vanilla
Beat in the egg and vanilla extract until fully combined, lending the batter richness, moisture, and a fragrant base note that complements the blueberries beautifully.
Step 5: Combine Wet and Dry Ingredients
Add the dry flour mixture and buttermilk alternately to the butter mixture, starting and finishing with the flour. Mix gently just until combined to avoid overworking the batter, which keeps the cake tender and delightfully soft.
Step 6: Fold in Blueberries and Lemon Zest
Gently fold in the fresh or frozen blueberries and optional lemon zest. The berries add juicy pockets of sweetness while the zest imparts a bright, citrusy aroma that elevates the entire cake.
Step 7: Bake to Perfection
Pour the batter into your prepared pan and spread it evenly. Bake for 35 to 40 minutes until the top is beautifully golden and a toothpick inserted into the center comes out clean. The result is a golden crust with a moist, tender interior.
Step 8: Cool and Slice
Let your cake cool slightly before slicing into squares. This brief rest allows the juices to settle, making the cake easier to cut and enhancing its flavors.
How to Serve Buttermilk Blueberry Breakfast Cake Recipe

Garnishes
Top your slices with a light dusting of powdered sugar or a dollop of whipped cream for extra indulgence. Fresh blueberries or a drizzle of honey also make lovely garnishes that echo the cake’s natural sweetness and freshness.
Side Dishes
This cake pairs wonderfully with a cup of your favorite coffee or tea, making your morning feel cozy and special. For a heartier brunch, serve alongside scrambled eggs or crispy bacon to balance the sweet with savory flavors.
Creative Ways to Present
For a fun twist, turn this cake into individual servings by baking it in muffin tins or layering it with yogurt and granola for a dessert parfait. You can also add a smear of cream cheese frosting for a celebratory touch that’s sure to impress guests.
Make Ahead and Storage
Storing Leftovers
Wrap any leftover cake tightly in plastic wrap or place it in an airtight container. Stored at room temperature, it will stay fresh for 2 to 3 days, making it easy to enjoy your Buttermilk Blueberry Breakfast Cake Recipe over a couple of mornings.
Freezing
This cake freezes beautifully! Slice it into squares, lay pieces out on a baking sheet to freeze individually, then transfer them to a freezer-safe bag. Frozen cake slices remain delicious for up to 3 months and thaw quickly at room temperature.
Reheating
Warm slices gently in the microwave for about 20 seconds or pop them in a toaster oven. Reheating brings back that fresh-baked feeling, reviving the moistness and making the blueberries juicy all over again.
FAQs
Can I use frozen blueberries in this recipe?
Yes! Frozen blueberries work perfectly here and add a lovely burst of flavor without losing their shape since you don’t need to thaw them first before folding into the batter.
What if I don’t have buttermilk?
No worries! You can make a simple buttermilk substitute by adding 1 tablespoon of lemon juice or white vinegar to ½ cup of milk. Let it sit for 5 minutes before using, and it will mimic the tangy moisture buttermilk provides.
Can I use a different fruit instead of blueberries?
Absolutely! This recipe is versatile. Try raspberries, blackberries, or diced peaches for a fresh take. Just be mindful of the moisture content and adjust baking times slightly if needed.
How do I know when the cake is done baking?
The best test is a clean toothpick inserted in the center. If it comes out clean or with just a few moist crumbs, your cake is perfectly baked and ready to come out of the oven.
Is this cake suitable for making ahead for a brunch?
Yes, it’s ideal for making ahead. Bake it the night before and keep it covered at room temperature or lightly warmed before serving to impress guests without last-minute stress.
