Make up the cake mix according to manufacturer’s instructions, line a cupcake pan with liners and deposit prepared cake mix (we used a #16 blue scoop to deposit our 1.5oz cupcakes here). Bake until cupcakes spring back lightly when touched, let cupcakes cool completely. Using leaf tips in red, yellow, and orange buttercream, pipe “fire” building one layer on the last. Top with pretzel rods as “logs”, tying the top with twine (this step is not required, they will be super cute without it!) and place a few toasted mini marshmallows on a toothpick and stick next to the “fire”.
