Lily Janehas great paper goods and offers these groundhog cupcake topper printables for free.
3 tablespoons butter or margarine
1 package (10 oz., about 40) regular marshmallows
6 cups rice crisp cereal
1. Melt butter or margarine in large sauce pan over low heat. Add marshmallows and stir until melted and well-blended. Cook 1-2 minutes longer, stirring constantly. Remove from heat.
2. Add rice crisp cereal. Stir until well coated.
3. Using buttered spatula or wax paper evenly press mixture into 13 x 9 x 2-inch pan coated with cooking spray.
4. While still warm, place M&M Candy's in the upper right hand side of the pan (or where ever you would like). In the upper left side of the rice Krispie bars, spread some icing* to make it look like melted snow. Place the groundhog topper decoration into the bars. See here how to make the groundhog topper and his shadow. For the chocolate frosting, I melted some chocolate chips in the microwave, then placed the melted chocolate in a ziploc bag, clipped one of the tips and decorated with "Happy Ground Hog Day".
Icing: Mix 1/2 cup powdered sugar with 2-3 teaspoons and a dash of vanilla
Happy Groundhog Day!
