Preheat oven to 425°F (220°C). Bake store-bought biscuits until golden for about 10-15 minutes, or bake homemade biscuits for 12-15 minutes until golden.

In a bowl, mix 1 cup sliced strawberries and 1 cup blueberries, let them sit for 10 minutes to create a syrup.

Whip 1 cup heavy cream until soft peaks form, add powdered sugar and vanilla, then whip to stiff peaks.

Slice biscuits in half, layer berry mixture and whipped cream on bottom half, then cap with top half.

Garnish with additional berries and serve immediately.
