Ingredients:1/3 Cup Butter or Margarine, softened1/3 Cup Brown Sugar1 Cup Flour1/4 Cup White Sugar1-8 oz Pkg. of Cream Cheese, softened1 Tsp. Vanilla1 Egg1/2 Cup Walnuts, optional1 Cup Plain M&M's, divided and crushed into small piecesBeat margarine and brown sugar until light and fluffy. Add flour and walnuts and mix well. Reserving half of the crumb mixture, press remaining crumb mixture onto the bottom of an 8" greased pan. Bake at 350 for 10 minutes. Beat cream cheese, then add sugar and vanilla, mixing at medium speed with an electric mixer until well blended. Add egg and mix well. After crust is done and still hot from the oven, put half a cup of crushed M&M's on the top, then pour cream cheese mixture on top of that. Combine leftover M&M's and crumb mixture, then sprinkle over cream cheese. Bake at 350 again for 20 minutes. This is so fun to make, especially for holidays when you can get M&M's in holiday colors! Enjoy!
