Follow the steps as indicated on the red velvet cake box - you are going to pour the batter into cupcake liners - under fill each liner this will create the ideal cupcake shape for the jar
Once the cupcakes are done baking place the cupcakes in the fridge to cool for 15 minutes ( perfect time to make the frosting )
Take each jar and place 1 cupcake then a dollop of frosting then 1 more cupcake then more frosting and finish off with sprinkles
Enjoy!
