Step 1

Preheat oven to 325 degrees F. Liberally grease a 9x13 rectangular baking pan with cooking spray; set aside.

Step 2

In a medium bowl, beat the heavy whipping cream with a mixer until stiff peaks form, about 5-7 minutes. Set aside. Meanwhile, cream together the eggs, sugar, and vanilla with the mixer in another large bowl until pale and fluffy, about 2 minutes. Add in the flour, baking powder, and salt until well blended. Fold in the whipped cream gently until fully incorporated and no streaks of whipped cream remain. Pour into the prepared baking pan.

Step 3

Bake for approximately 30-40 minutes or until a toothpick inserted near the center comes out clean or with moist crumbs. Cool completely before cutting into squares. Dust with confectioners' sugar if you'd like and serve up with more fresh whipped cream and fresh berries.
