Blueberry Buckle – Moist, Sweet & Fruity

If you love tender cake with bursts of juicy berries, the Blueberry Buckle is a classic treat that hits all the right notes. “Buckle” gets its name from the way the fruit causes the cake to “buckle” slightly during baking, creating a rustic, homey appearance and a soft, buttery texture.

Think of it as a cross between a simple Coffee Cake and a blueberry muffin, but with a more tender, cake-like crumb and a sweet crumb topping.

🛒 Ingredients

For the Cake:

2 cups all-purpose flour
1½ teaspoons baking powder
½ teaspoon baking soda
½ teaspoon salt
½ cup unsalted butter, softened
1 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
1 cup buttermilk (or milk + 1 tsp lemon juice)
1½ cups fresh or frozen blueberries

For the Crumb Topping:

½ cup all-purpose flour
½ cup granulated sugar
¼ cup unsalted butter, cold and cubed
½ teaspoon cinnamon (optional)

👩‍🍳 Step-by-Step Instructions

Step 1: Preheat & Prepare Pan

Preheat oven to 175°C (350°F).
Grease a 9-inch square baking pan or line with parchment paper.

Step 2: Make the Crumb Topping

In a small bowl, combine flour, sugar, and cinnamon.
Cut in cold butter using a pastry cutter or fork until mixture resembles coarse crumbs.
Set aside.

Step 3: Mix Dry Ingredients

In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.

Step 4: Cream Butter & Sugar

In a large bowl, beat softened butter and sugar until light and fluffy.
Add eggs one at a time, beating well. Stir in vanilla extract.

Step 5: Combine Wet & Dry

Alternate adding dry ingredients and buttermilk to the butter mixture:

Add ⅓ dry mix, then ½ buttermilk, repeating until fully combined.
Fold in blueberries gently to avoid breaking them.

Step 6: Assemble & Add Topping

Pour batter into prepared pan and spread evenly.
Sprinkle crumb topping evenly over the batter.

Step 7: Bake

Bake for 45–55 minutes, or until a toothpick inserted comes out clean and top is golden.

Cool in the pan for 10–15 minutes before slicing.

💡 Tips for Perfect Blueberry Buckle

Toss blueberries in 1–2 tablespoons of flour before folding to prevent sinking.
Use fresh or frozen blueberries (no need to thaw frozen).
Don’t overmix batter — fold gently for tender cake.
Slightly underbake if you like extra moist texture; it will continue to cook as it cools.
