Ingredients You’ll Need
What makes this cake so special? It’s honestly the simple yet well-chosen ingredients that let each component shine. From the richness of buttermilk and the pop of blueberries to the buttery crumb, every element works together to create magic!
- Unsalted butter, softened: Gives the cake its rich, melt-in-your-mouth texture. Letting it reach room temperature ensures a smooth batter.
- Sugar: Adds sweetness and also helps to aerate the butter for a light crumb.
- Eggs: Add structure and moisture, ensuring your Blueberry Buttermilk Breakfast Cake stays tender.
- Vanilla extract: Brings out the flavors of both the buttermilk and berries with its warm, aromatic note.
- All-purpose flour: The foundation for a sturdy yet soft cake—perfect for soaking up those blueberry juices.
- Baking powder: Lifts the cake, making it fluffy rather than dense.
- Salt: Balances sweetness and intensifies all the flavors.
- Buttermilk: Adds a delicious tang and makes the crumb incredibly moist and tender. Don’t skip it!
- Blueberries (fresh or frozen): The star of the show; their sweet-tart burst is gorgeous and colorful.
- Powdered sugar: Essential for a smooth, sweet glaze that ties everything together.
- Milk (for glaze): Loosens the glaze so it can be drizzled dreamily over the finished cake.
How to Make Blueberry Buttermilk Breakfast Cake
Step 1: Preheat and Prepare Your Pan
Start by setting your oven to 350°F (175°C). As it preheats, lightly grease a 9×13-inch baking dish. This gives the Blueberry Buttermilk Breakfast Cake its classic sheet-cake look and ensures easy releasing once it’s baked.
Step 2: Cream Butter and Sugar
In a large mixing bowl, beat the softened butter with sugar until the mixture looks pale and fluffy. This airiness is the first step to a cake with a delicate, soft crumb. Don’t rush this step; a good three minutes with a hand mixer makes all the difference.
Step 3: Add in Eggs and Vanilla
Crack in the eggs one at a time, mixing well after each. This helps to emulsify the batter, so it bakes up even and moist. Add a splash of vanilla extract and mix just until combined, infusing the cake with cozy aroma right from the start.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking powder, and salt. Combining dry ingredients beforehand guarantees your Blueberry Buttermilk Breakfast Cake rises evenly and has a uniform crumb all the way through.
Step 5: Mix It All Together
With the wet bowl ready, gradually add the dry mixture, alternating with buttermilk. Always begin and end with flour. This keeps the cake’s texture soft and prevents overworking the batter, which could make it tough.
Step 6: Fold in Blueberries
Gently fold in the blueberries with a spatula, being careful not to overmix. Whether you use fresh or frozen, this step ensures those little blueberry pockets stay whole, giving every bite of Blueberry Buttermilk Breakfast Cake the perfect burst of fruit.
Step 7: Pour and Bake
Spread the batter evenly in your prepared pan. Bake for 35-40 minutes; when a toothpick inserted in the center comes out clean, it’s ready. The aroma will make it hard to wait, but patience pays off here!
Step 8: Glaze and Enjoy
While the cake cools a bit, whisk together the powdered sugar and milk for a silky glaze. Drizzle it over the warm cake, letting it seep into the cracks. This step adds just the right touch of extra sweetness and shine.
How to Serve Blueberry Buttermilk Breakfast Cake

Garnishes
Dress up your Blueberry Buttermilk Breakfast Cake with a sprinkle of extra fresh blueberries, a dusting of powdered sugar, or a few strips of lemon zest for color and zing. If you’re feeling a little decadent, a dollop of whipped cream on top never hurts!
Side Dishes
This cake is wonderful on its own, but it also shines alongside a spread of breakfast favorites. Think creamy Greek yogurt, crispy bacon, or a platter of seasonal fruit. Pair it with a hot cup of coffee or tea to round out the morning.
Creative Ways to Present
Try cutting the Blueberry Buttermilk Breakfast Cake into small squares for a brunch buffet, or serve as generous slices for a cozy weekend breakfast. You can even layer crumbled cake with yogurt and extra berries for a quick parfait. It’s delightfully versatile!
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftovers, you’re in luck. Blueberry Buttermilk Breakfast Cake keeps beautifully at room temperature, covered airtight, for up to two days. For longer freshness, pop it in the fridge for up to a week—just make sure it’s tightly wrapped so it doesn’t dry out.
Freezing
For longer storage, the cake can be frozen. Slice it into portions, wrap each in plastic wrap, then layer them in a freezer-safe container. Freeze for up to three months. When you’re ready for a sunny morning treat, thaw a piece at room temperature or gently reheat it.
Reheating
To bring back that fresh-baked texture, simply warm a slice in the microwave for 10-20 seconds, or pop a few slices in a 300°F oven for about five minutes. The glaze may melt a little, but the cake will taste just as heavenly as the day it was baked.
FAQs
Can I use frozen blueberries instead of fresh?
Absolutely! Frozen blueberries work perfectly in this recipe for Blueberry Buttermilk Breakfast Cake. Add them straight from the freezer—no need to thaw. This helps prevent the berries from turning the batter purple.
What if I don’t have buttermilk?
No buttermilk? No problem. Make your own by mixing just under 1/2 cup milk with 1/2 tablespoon lemon juice or white vinegar. Let it sit for five minutes, then use as directed for that signature tender crumb.
Can I make this cake gluten-free?
Yes! Substitute your favorite 1:1 gluten-free baking flour for the all-purpose (check that it contains xanthan gum or add a pinch). The results are still delicious and satisfyingly fluffy.
Is this Blueberry Buttermilk Breakfast Cake very sweet?
It’s lightly sweet, designed for breakfast or brunch—a little less sugary than a dessert cake. The glaze adds just enough extra sweetness without overdoing it. You can adjust the sugar slightly to taste if you prefer.
Can I double the recipe for a larger crowd?
Yes, you can! Bake it in two 9×13 pans or use a half-sheet pan. Just keep an eye on the bake time—a larger cake could need a few extra minutes to cook through.
Final Thoughts
If you love the simple pleasure of home-baked goodness, you must give Blueberry Buttermilk Breakfast Cake a try. Every forkful is soft, fruity, and full of love—perfect for sharing or savoring all to yourself. Grab your mixing bowl and add a little joy to your next breakfast!
