EASY IRISH CREAM FUDGE

3 cups powdered sugar
1 cup plus 4 tbsp Bailey's Irish Cream, divided use
4 1/3 cups chocolate chips (use semisweet for rich fudge), divided use
1 cup vanilla chips or choc chips (or more semisweet)
1/4 cup plus 2 tbsp butter, divided use
1/2 cup chopped nuts, optional

Sift powdered sugar and whisk together with 1 cup of the Bailey's to get lumps out. Melt 3 cups of the chocolate chips, vanilla chips and 1/4 cup of the butter over low heat, stirring constantly until just melted. Pour in Bailey's and powdered sugar mix and blend well. Stir in nuts, if using. Spread into greased 8-inch square pan.

TO PREPARE THE TRUFFLE TOPPING:
Melt remaining 2 tbsp butter and remaining 1 1/3 cup chocolate for truffle topping in separate pan and add the remaining 4 tbsp Bailey's when just melted. Spread over fudge with knife or spatula. Let set in fridge for 2 hours. Cut and serve.
