Start creating this colorful cupcake by baking up your favorite store bought cake mix. Instead of following the box directions, make your cake extra decadent by adding an additional egg. You will also want to add a splash of vanilla and to replace any oil with butter and any water with milk. Bake until a fork comes out clean.

Create your own custom My Little Pony cupcake toppers by adhering a trimmed Mint Striped Paper Straws to the back of a My Little Pony themed confetti found in the My Little Pony Friendship is Magic Centerpiece Set. A simple dot of hot glue should hold this in place. Then add the toppers to the cupcakes!
