Blueberry Buttermilk Biscuits with Vanilla Buttercream Frosting

These blueberry buttermilk biscuits topped with a light vanilla buttercream are a delightful treat for brunch, afternoon tea, or a cozy dessert. The biscuits are tender and flaky with bursts of fresh blueberries, while the buttercream adds a smooth, sweet finish that pairs perfectly with the subtle tang of buttermilk. This recipe is approachable for bakers of all skill levels and delivers a lovely balance of buttery richness and fruity freshness.

Ingredients

• 2 cups all-purpose flour
• 1 tablespoon baking powder
• 1/2 teaspoon baking soda
• 1 teaspoon salt
• 2 tablespoons granulated sugar
• 6 tablespoons cold unsalted butter, cubed
• 3/4 to 1 cup cold buttermilk
• 1 cup fresh blueberries (or frozen, not thawed)
• For the vanilla buttercream: 4 tablespoons unsalted butter, softened; 1–1 1/2 cups powdered sugar; 1/2 teaspoon vanilla extract; 1–2 tablespoons milk or cream

Instructions

1. Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper.
2. In a large bowl, whisk together the flour, baking powder, baking soda, salt, and sugar.
3. Cut the cold butter into the dry ingredients with a pastry cutter or two forks until the mixture resembles coarse crumbs with some pea-sized pieces of butter remaining.
4. Pour in 3/4 cup cold buttermilk and gently stir until a shaggy dough forms. Add a little more buttermilk if needed; the dough should be just cohesive and slightly sticky but not wet.
5. Turn the dough out onto a lightly floured surface and gently fold in the blueberries, being careful not to crush them. Pat the dough into a rectangle about 1-inch thick.
6. Use a biscuit cutter or knife to cut rounds or squares. Place the biscuits on the prepared baking sheet, spacing them slightly apart for a crisp exterior or close together for softer sides.
7. Bake for 12–15 minutes, until the tops are golden brown and a toothpick inserted into the center comes out clean. Remove from the oven and transfer to a wire rack to cool briefly.
8. While the biscuits cool, make the vanilla buttercream: beat the softened butter until smooth, then gradually add powdered sugar until you reach the desired sweetness. Mix in the vanilla and enough milk or cream to reach a spreadable consistency.
9. When the biscuits are warm (not piping hot), spread or pipe a thin layer of buttercream on top. Serve warm or at room temperature. Leftovers keep well refrigerated for a couple of days; bring to room temperature before serving.

Notes

• Use very cold butter and cold buttermilk for the best flaky texture.
• Gently handle the dough to keep biscuits tender; overworking will make them tough.
• If using frozen blueberries, fold them in while still frozen to prevent color bleeding and a mushy texture.
• Adjust the buttercream sugar to taste and add a pinch of salt if you prefer a less sweet finish.
