Impossible Peanut Butter and Chocolate Pie recipe

1 cup packed brown sugar
1/2 cup Bisquick
2 eggs
1 cup whipping cream
2/3 cup chunky peanut butter
1 (6 ounce) package chocolate chips (1 cup)

Heat oven to 350 degrees F.

Beat all ingredients, except chocolate chips, in a large bowl on high speed, scraping bowl occasionally until fluffy, one minute (do not use blender). Pour into an ungreased 9-inch pie plate. Bake until puffed and dry in center and knife inserted in center comes out clean, about 35 minutes. Cool slightly.

Heat chocolate chips in 1-quart saucepan over low heat, stirring occasionally, until melted. Spread over pie. Sprinkle with chopped peanuts, if desired. Refrigerate until chocolate is firm, about 1 hour.
