Heat oven to 350°F. Spray 12-cup fluted tube cake pan with cooking spray or grease with butter.
Separate dough from 2 cans Pillsbury™ Grands!™ Homestyle Butter Tastin’™ refrigerated biscuits into 16 biscuits. Cut each biscuit into quarters; place in large bowl.

In small microwavable bowl, microwave 2 tablespoons strawberry jam on High 10 seconds; stir. Drizzle over biscuit pieces. Add remaining biscuit pieces to pan.

Just before serving, in medium bowl, beat 1 cup whipping cream with electric mixer until soft peaks form. Spread cream over top of monkey bread. Garnish with remaining 2 cups sliced fresh strawberries. Serve immediately.
