Preheat oven to 325 degrees. In a mixing bowl, combine eggs, spice cake mix and pumpkin until well blended.
Pour mixture into a 9×13 baking pan. Bake for 25-30 minutes or until a toothpick inserted comes out clean.
Once your cake has cooled completely, use a cookie scoop or a small spoon to carefully add cake into the jars. Start by adding 1-2 scoops in the bottom of each jar and then alternate with a dollop of cream cheese icing. If you have a piping bag or ziplock bag handy, it’s easiest to pipe the icing into the jar rather than trying to scoop it in.
After the jars are filled, top the icing with sprinkles!
Tie a wooden fork around the top of each jar with a strip of fall fabric.
Lastly, pick up a few recipe cards and jot down just how simple the Pumpkin Spice Cake is to make. It’s a cute extra you can gift with the cake jars.
