Crispy Peanut Butter Chocolate Rolls

1. Begin by combining the first 4 ingredients (white corn syrup, smooth peanut butter, sugar, 3 tbsp butter) in a pot. Bring to a boil and immediately remove from heat.
2. Add in cereal and mix until coated. Spread on a sheet of wax paper and press into a rectangle. Let set for 15 minutes.
3. While the rectangle sets, beat the 5 filling ingredients (icing sugar, cocoa, 1/2 cup softened butter, water, vanilla) in a bowl until smooth. Add more water if necessary.
4. Spread the chocolate filling evenly on the cereal rectangle. Roll up and cover with plastic wrap. Chill and enjoy!
