Impossible Peanut Butter Chocolate Pie

1 c. packed brown sugar
1/2 c. Bisquick mix
2 eggs
1 c. whipping cream
2/3 c. chunky peanut butter
1 (6 oz.) pkg. chocolate chips (1 c.)

Heat oven to 350 degrees. 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 pie plate, 9 x 1 1/4. 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..
