Mixed Berry Buckle

This Mixed Berry Buckle is the kind of cozy cake that feels effortlessly special. It bakes up buttery and soft with juicy berries tucked into every bite, while the golden cinnamon crumble on top adds just the right amount of texture. Somewhere between a coffee cake and a tender fruit cake, this recipe feels equally perfect for brunch, dessert, or a quiet afternoon with coffee.

The mix of berries makes every slice a little different, which honestly adds to the charm. Sweet blueberries, jammy raspberries, and bursts of blackberry or strawberry bake beautifully into the tender crumb. Even better, this mixed berry buckle is simple to make and wonderfully forgiving for home bakers.

Fun baking fact: traditional buckles got their name because the soft cake lightly “buckles” around the fruit as it bakes — part of what makes them feel so cozy and homemade.

Recipe Yield: 8 servings

INGREDIENTS

2 cups all-purpose flour
1 tsp baking powder
½ tsp baking soda
½ tsp salt
½ cup unsalted butter, softened
¾ cup granulated sugar
2 large eggs, room temperature
1 tsp vanilla extract
¾ cup buttermilk, room temperature
1¾ cup mixed berries (blueberries, raspberries, blackberries, and/or chopped strawberries)
1 tbsp all-purpose flour (for berries)

Crumb Topping
⅓ cup all-purpose flour
¼ cup light brown sugar
¼ tsp cinnamon
Pinch of salt
3 tbsp cold unsalted butter, cubed

INSTRUCTIONS

1. Prep the pan:
Preheat oven to 350°F (175°C). Lightly grease a 9-inch round cake pan and line the bottom with parchment paper for easier release.

2. Mix the dry ingredients:
In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.

3. Cream the butter and sugar:
In a large bowl, beat softened butter and sugar for 2–3 minutes until light and fluffy. Then mix in eggs, one at a time, followed by vanilla extract.

4. Finish the batter:
Gradually add the dry ingredients in three additions, alternating with buttermilk. Mix gently just until combined to keep the cake soft and tender.

5. Add the berries:
Toss mixed berries with 1 tbsp flour. Then gently fold them into the batter. Spread the batter evenly into the prepared pan.

6. Make the crumble:
In a small bowl, combine flour, brown sugar, cinnamon, and salt. Cut in cold butter with a fork until crumbly with some pea-sized pieces remaining. Sprinkle evenly over the batter.

7. Bake until golden:
Bake for 45–52 minutes, or until the top is golden and a toothpick inserted into the center comes out with a few moist crumbs but no wet batter. If browning too quickly, loosely tent with foil during the final 10 minutes.

8. Cool and slice:
Let cool in the pan for 20 minutes before removing. Allow to cool another 10–15 minutes for cleaner slices, although it’s especially delicious slightly warm.

Helpful Tips to Perfect This Recipe

• Toss berries in flour for even distribution: This simple step helps prevent berries from sinking, so every slice of your mixed berry buckle has fruit throughout.
• Use room temperature ingredients: Softened butter, eggs, and buttermilk blend more evenly, creating a lighter, more tender crumb.
• Don’t overbake: Because berries release moisture while baking, check the buckle near the 45-minute mark. A few moist crumbs are perfect — fully dry can mean the cake loses softness.
