Instructions
Preheat oven to 375 and line cookie sheet with parchment paper.
Cream together butter, shortening, and peanut butter for 30 seconds.
Add 1 cup of flour, white sugar, brown sugar, eggs, baking soda, baking powder, and vanilla.
Stir together slowly, then beat til thoroughly combined.
Beat in remaining flour.
Optional: Chill for 30 minutes. This makes the dough a bit easier to handle, and your cookies will spread less in the oven. However, the step can be skipped. It's not a difficult dough to handle warm.
Shape dough into 1-inch balls. Place on cookie sheet, and flatten slightly with the bottom of a glass dipped in sugar.
Bake at 375 for 7 to 9 minutes, or until bottoms are lightly browned.
Cool for 5 minutes on cookie sheet, then transfer to wire racks to cool completely.
Topping
In a double boiler, or using the "soften/melt" setting of your microwave, melt peanut butter baking chips in glass bowl.
While the chips are melting, break up the peanut brittle into small pieces (nickel-dime sized or smaller).
Using a small spatula, spread a dab of melted peanut butter chips onto cookie, then quickly sprinkle with peanut brittle pieces.
