Halloween Rice Krispie Treat Cake

Directions

1. Microwave 1 tablespoon of butter until melted, then brush it all over the inside of a bundt pan.
2. In a large pot or Dutch oven, melt the remaining 4 tablespoons of butter with the mini marshmallows, stirring constantly with a wooden spoon.
3. Once the butter and marshmallows are fully melted and combined, immediately stir in the Rice Krispies cereal, working quickly to coat every piece. Reduce the heat to low or use the 'keep warm' setting.
4. Press half of the Rice Krispie mixture into the prepared bundt pan, pushing it up the sides to form a well in the center.
5. Spoon the marshmallow creme into the well you created.
6. Cover the marshmallow creme with the remaining Rice Krispie mixture, pressing down firmly to seal any gaps.
7. Let the cake cool completely to room temperature before inverting it onto a serving plate. If you unmold it too soon, it will be too soft and may collapse.
8. Decorate the cake with festive frosting and sprinkles as desired.
