Press 1 slice in bottom and up side of each mini muffin cup, forming 1/4-inch rim above top of cup (dust fingers with flour if necessary). Bake 10 to 15 minutes or until edges are deep golden brown. Cool in pans on wire racks 5 minutes. With tip of handle of wooden spoon, press dough down in center of each cup to make room for 2 tablespoons filling. Meanwhile, in 2-quart saucepan, melt white chips and 3/4 cup of the peanut butter over low heat, stirring constantly. Divide mixture evenly into cookie cups (about 1 tablespoon each). Refrigerate 10 minutes. In same 2-quart saucepan, melt chocolate chips and remaining 3/4 cup peanut butter over low heat, stirring constantly. Divide chocolate mixture evenly on top of peanut butter mixture in each cup (about 1 tablespoon each). Sprinkle crushed granola bars over top of each. Refrigerate until set, about 1 hour. Remove from muffin cups before serving. High Altitude (3500-6500 ft): Break up cookie dough into bowl; knead or stir 1/4 cup flour into dough. Divide dough into 24 pieces; press 1 piece in each cup.
