Ingredients

2 cups all-purpose flour
1 cup granulated sugar
½ cup unsalted butter, melted and cooled
1 cup buttermilk, at room temperature
2 large eggs
1 ½ teaspoons vanilla extract
2 teaspoons baking powder
½ teaspoon baking soda
½ teaspoon salt
2 cups fresh blueberries (or frozen, unthawed)
2 tablespoons coarse sugar (for topping, optional)

Directions

Prep Time: 15 minutes | Cooking Time: 35-40 minutes | Total Time: 55 minutes

Step 1: Prepare Your Pan & Oven

Preheat your oven to 350°F (175°C). Grease and flour a 9x9-inch baking pan, or line it with parchment paper for easy removal.

Step 2: Mix the Wet Ingredients

In a large bowl, whisk together the melted butter, sugar, and eggs until smooth and creamy. Stir in the buttermilk and vanilla extract until well combined.

Step 3: Combine the Dry Ingredients

In a separate bowl, sift together the flour, baking powder, baking soda, and salt. Add the dry mixture to the wet mixture, stirring gently until just combined (do not overmix).

Step 4: Fold in the Blueberries

Gently fold in the blueberries until evenly distributed throughout the batter.

Step 5: Bake

Pour the batter into the prepared pan and smooth the top. Sprinkle with coarse sugar if desired for a crunchy top. Bake for 35-40 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs.

Step 6: Cool & Serve

Let the cake cool in the pan for at least 10 minutes. Slice and serve warm or at room temperature.

Notes

For best results, use room temperature eggs and buttermilk to ensure a tender crumb.
If using frozen blueberries, do not thaw to prevent the batter from discoloring and becoming too wet.
Dust blueberries lightly in flour before adding to batter to help prevent sinking.

Variations

Lemon Blueberry Buttermilk Explosion: Add 1 tablespoon fresh lemon zest to the batter.
Streusel Topping: Mix ¼ cup brown sugar, 3 tablespoons flour, and 2 tablespoons cold butter for a crumb topping before baking.
Mixed Berry Explosion: Substitute half the blueberries with raspberries or blackberries for a berry medley.

Pro Tips

Check doneness at 35 minutes—overbaking can dry out the cake, so aim for a moist crumb.
Gently fold berries to avoid breaking them and streaking the batter.
Let the cake cool at least 10 minutes before slicing for cleaner cuts and better texture.
