Buttermilk Blueberry Breakfast Cake
This easy, summery Lemon Blueberry Buttermilk Cake is sure to brighten any morning. Honestly, it’s hard not to have a great day when you get to eat coffee cake for breakfast. This particular lemon blueberry cake is made with buttermilk which adds a great tangy flavor, but also makes the cake super moist and tender.
Don’t have buttermilk at home? No problem - it’s a cinch to make yourself. Just throw a tablespoon of lemon juice into a one cup measuring cup, fill to the top with milk, give it a little stir and wait for 10 minutes. Bam, homemade buttermilk!
You can make this breakfast cake with fresh or frozen blueberries, or any other berries that you want. Or, feel free to swap out the lemon zest with orange or lime zest, and use different types of flavor extracts. Pro tip: it also makes a great dessert, served with a scoop of vanilla ice cream or dollop of whipped cream.
Ingredients in Lemon Blueberry Buttermilk Cake
- Butter - you’ll need room temperature unsalted butter for this recipe.
- Sugar - this recipe calls for white granulated sugar.
- Egg - any kind of large egg will work.
- Lemon Zest - fresh lemon zest really brightens this cake and compliments the buttermilk and blueberry flavors. If you seriously love lemon, you could add a ½ teaspoon of lemon extract as well.
- Vanilla Extract - pure vanilla extract tastes best.
- Flour - we usually use all-purpose flour but cake flour would also work great.
- Baking Powder - this helps the cake rise and keeps it super soft and tender.
- Salt - sea salt or kosher salt work great.
- Buttermilk - you can use either full fat or nonfat buttermilk. It adds a beautiful tangy flavor that tastes amazing with lemon and blueberries.
- Blueberries - we’ll usually use fresh blueberries but you can absolutely use frozen berries. You don’t even need to thaw them - just toss them right into the batter. This recipe will also work with raspberries, strawberries, blackberries or even mixed berries.
- Sugar for topping - this is optional but sprinkling sugar on top of the cake batter just before baking makes a beautiful little sugar crust.
How to Make a Lemon Blueberry Buttermilk Cake
- Cream the butter and sugar. In the bowl of a stand mixer, add the room temperature butter and sugar. Using the paddle attachment, beat until light and fluffy, or about 3 minutes.
- Mix the cake batter. Slowly add the egg, lemon zest, and vanilla and mix on low speed until smooth. Stop the mixer and add the flour, baking powder, and salt, then mix on low speed just until almost combined. Add the buttermilk and continue mixing on low until well mixed. Finally, use a rubber spatula to carefully fold in the fresh blueberries by hand.
- Add batter to cake pans. Transfer the batter to a buttered or parchment paper-lined 9" x 9" baking dish, using an offset spatula to spread evenly. Sprinkle about 2 tablespoons of coarse sugar over the cake batter just before baking.
- Bake. Bake in a preheated 350-degree oven for 45 minutes, or until a toothpick inserted into the center comes out clean.
- Cool and serve. Remove the cake from the oven and let cool completely on a cooling rack before slicing. Enjoy!
Frequently Asked Questions
This recipe calls for baking the Lemon Blueberry Buttermilk Cake in a 9” x 9” baking dish. However, you could easily bake the cake batter in two 8” loaf pans or muffin pans. The only thing you will need to adjust is the baking time. Keep an eye on the cakes and test doneness by inserting a toothpick into the center to see if it comes out clean.
One trick to keep the blueberries on top rather than all sinking to the bottom is to toss the blueberries in a little bit of flour just before folding them into the batter. It creates a little resistance and helps hold them in place while the cake bakes.
You can easily make your own buttermilk at home! In a one cup measuring cup, 1 tablespoon of lemon juice then fill to the top with whole milk. Mix and let sit for 10 minutes. Voila!
Sure! You can make the batter, spread it into your baking dish, cover with plastic wrap and store in the fridge overnight. The next day, let it come to room temperature for about 30 minutes while you preheat the oven and then bake as instructed.
Storing and Freezing
- Storing - your Lemon Blueberry Buttermilk Cake should be covered and stored either at room temperature for up to 3 days or in the fridge for up to 1 week.
- Freezer - you can also wrap your cake and store frozen for up to 3 months. To thaw, transfer to the fridge or room temperature overnight.
