Preparation
Step 1Preheat oven to 350° and line 2 muffin tins with 16 cupcake liners. In a large bowl, mix together cake mix, vegetable oil, eggs, and 1 cup Rumchata until smooth. Bake until a toothpick comes out with minimal crumbs, about 25 minutes. Let cool completely before frosting. Step 2Make Rumchata frosting: In a large bowl, combine butter, 2 cups powdered sugar, vanilla, cinnamon, salt, and remaining ⅓ cup Rumchata. Using a hand mixer, beat until smooth. Add the remaining 2 cups powdered sugar and beat until light and fluffy. Step 3Pipe frosting onto cooled cupcakes and garnish with more cinnamon and a decorative straw.
