Cake Batter Rice Krispy Treats

This recipe was brought to our last Recipe Club and was delicious. It was given to me to add by Kristen Hoffman.

3 TBSP Butter
1 (10 oz) bag mini marshmallows
1/3 cup dry, yellow cake mix (just the cake mix alone)
4 cups rice krispies
1 (1.75 oz) container of sprinkles

Melt butter in microwave (30 seconds). Add marshmallows. Cook 30 seconds and stir in a bit of cake batter. Repeat until melted. Add rice krispies and 1/2 the sprinkles. Press into an 8x8 pan. Use the remainder of the sprinkles on top. Let cool for 30 min.
