Bake your favorite cupcake mix and cool completely. Be sure to only fill the cupcake liner or pan full. Trim the top of the cupcake if needed. If you over fill the pan the cupcake top will be too large and will not fit into the opening of the mason jar.
Almost No-Bake Layered Pumpkin Pie in a Jar recipe. uses cream cheese and whipped cream in one layer, pumpkin and vanilla pudding in another. I love this! I wonder who will be hosting Thanksgiving this year.
