Preparation
In a large bowl, combine the cake mix, water, eggs, oil and extract; beat on low speed for 30 seconds. Beat on medium for 2 minutes.
Pour into three greased and floured 9-in. round baking pans. Bake at 350° for 18-22 minutes or until a toothpick inserted in the center comes out clean. Cool for 10 minutes before removing from pans to wire racks to cool completely.
Place white chips in a large bowl. In a small saucepan, bring cream just to a boil. Pour over chips; whisk until smooth. Stir in butter. Chill for 30 minutes, stirring once.
Beat on high for 2-3 minutes or until soft peaks form and frosting is light and fluffy. Set aside 2-1/2 cups for frosting cake. Stir patties into remaining frosting.
Place one cake layer on a serving plate; spread with half of the peppermint patty filling. Repeat layers. Top with remaining cake layer. Frost top and sides of cake with reserved frosting. Store in the refrigerator. Garnish with additional patties.
