Blueberry Boy Bait is one of my go-to nostalgic cakes—sweet, simple, and packed with juicy blueberries. No frosting needed and always a hit with my family.
Preheat the oven to 350°F. Line an 8-inch square metal baking pan with parchment paper, leaving an overhang on the sides for easy lifting.
Whisk together the flour, baking powder, salt, and baking soda in a medium bowl.
Cream the butter and sugar in a large bowl using an electric mixer on medium speed for 2 to 3 minutes until light and fluffy.
Add the eggs one at a time, beating well after each. Mix in the vanilla extract.
Mix the dry ingredients and buttermilk into the butter mixture in alternating additions, beginning and ending with the flour mixture. Keep the mixer on low speed.
Fold in the blueberries gently to avoid breaking them.
Spread the batter evenly in the prepared pan and smooth the top.
Combine the topping ingredients in a small bowl, then sprinkle the cinnamon sugar evenly over the batter.
Bake for 35 to 40 minutes, or until a wooden pick inserted in the center comes out clean.
Cool the cake in the pan for 10 minutes. Use the parchment to lift it out and transfer to a wire rack to finish cooling.
Notes
Chef Jenn’s Tips
Toss blueberries with a little flour before folding them into the batter to keep them from sinking.
For extra flavor, add lemon zest to the batter.
Don’t overmix once the flour is added—this keeps the cake tender.
This recipe works well with frozen blueberries too—no need to thaw first.
