1In chilled medium bowl, beat whipping cream and powdered sugar with electric mixer on high speed until stiff peaks form. Fold in strawberries and blueberries.
2Heat Belgian or regular waffle iron (Waffle irons without a nonstick coating may need to be brushed with vegetable oil or sprayed with cooking spray before batter for each waffle is added.)
3In small bowl, beat eggs with electric mixer on high speed about 3 minutes or until thick and lemon colored. Beat in milk. Beat in Bisquick and granulated sugar on low speed until smooth. Gently fold in oil. Pour batter onto hot waffle iron. (Check manufacturer's directions for recommended amount of batter.) Close lid of waffle iron.
4Bake about 5 minutes or until steaming stops. Carefully remove waffle. Top each waffle with berry cream and additional berries.
