This blueberry buttermilk breakfast cake is the kind of treat I wish I could serve every lazy Saturday morning The tender crumb melts in your mouth thanks to the buttermilk and sweet juicy blueberries pop in every bite I learned how to make this from my grandmother and now it is my family’s favorite pick for cozy brunches and holiday mornings
The first time I brought this cake to a family picnic it was gone before I had a slice Now my husband requests it every year for his birthday breakfast and I am happy to oblige
Ingredients
- All purpose flour: provides the structure for both the cake and crumble topping Look for unbleached flour for best flavor
- Baking powder and baking soda: give lift and lightness Make sure yours are fresh to ensure a fluffy cake
- Salt: balances the sweetness and highlights blueberry flavor Fine sea salt is ideal
- White sugar: sweetens both the batter and crumble Choose pure cane sugar if available
- Butter: is key for richness and a tender crumb Go for high quality unsalted butter at room temperature
- Eggs: add structure and moisture Fresh large eggs work best and should be at room temperature for smooth mixing
- Vanilla extract: brings background warmth and depth Use pure vanilla for best results
- Buttermilk: gives the cake its delicate tang and extra moistness Whole buttermilk if you can find it or add lemon juice to regular milk as a quick swap
- Fresh blueberries: burst with sweet tart flavor Use plump ripe berries and save some to scatter on top before baking for a beautiful finish
Instructions
- Prepare the Pan:
- Grease a 9 x 13 inch pan generously with butter or cooking spray This prevents sticking and ensures easy removal of the cake after baking
- Mix the Dry Ingredients:
- Sift together all purpose flour baking powder baking soda and salt in a medium bowl Sifting helps prevent clumps and ensures even distribution of leaveners for an evenly risen cake
- Cream Butter and Sugar:
- Beat the butter and white sugar together in a large mixing bowl Use a handheld or stand mixer on medium speed and beat until the mixture is very light and fluffy This step takes about three to five minutes and makes a difference in the cakes tenderness
- Incorporate Eggs and Vanilla:
- Add eggs one at a time mixing well after each addition so the batter stays smooth and cohesive Stir in the vanilla extract for extra flavor depth
- Combine Wet and Dry Ingredients:
- Mix in the sifted dry mixture and buttermilk alternating between each and mixing gently Start and end with the dry ingredients This keeps the batter light Do not overmix or you risk a dense cake
- Fold in Blueberries:
- Gently fold in the fresh blueberries with a spatula taking care not to crush them Scattering some berries on top before baking gives the finished cake a lovely appearance
- Prepare the Crumble Topping:
- In a small bowl mix together flour and sugar then cut in the softened butter Use your fingertips or a fork to create coarse crumbs that clump together Sprinkle this evenly over the top of the batter
- Bake the Cake:
- Place the pan in a preheated 350 degree oven Bake for 45 to 60 minutes Check doneness by inserting a toothpick in the center If it comes out clean or with just a few crumbs the cake is done The top should be golden brown and the topping slightly crisp
- Cool and Serve:
- Allow the cake to cool in the pan on a wire rack at least 20 minutes This lets the crumb set and prevents crumbling when you cut and serve

My favorite part about this recipe is the golden crumble topping As a child I would sneak into the kitchen and pinch those crispy edges as soon as the cake came out of the oven Now I let my daughter help sprinkle the crumble and we laugh about keeping the family tradition alive

Once the cake is cool cut it into squares and store them in an airtight container at room temperature for up to two days For longer storage refrigerate for up to five days Just let slices come to room temperature or rewarm briefly before serving
Ingredient Substitutions
You can use frozen blueberries instead of fresh Just toss them in a bit of flour to prevent excess bleeding into the batter If you are out of buttermilk stir a tablespoon of white vinegar or lemon juice into regular milk and let it sit for five minutes
