Equipment Needed:

  • 6″ or 8″ cake pans
  • Baking spray
  • Parchment paper
  • Food processor
  • Measuring cups and spoons
  • Large mixing bowl
  • Whisk
  • Sifter
  • Rubber spatula
  • Toothpick
  • Cooling rack
  • Plastic wrap

Ingredients Needed:

For Graham Cracker Crust:

  • 12 whole Cinnamon Graham Crackers 
  • 8 TBS butter melted

For Key Lime Buttercream:


To make the cake, you’ll preheat your oven and prepare your cake pans with baking spray and parchment paper. 

Then, you’ll make the graham cracker crust by pulsing the graham crackers and melted butter in a food processor and pressing the mixture into the bottom of your cake pans.

Next, you’ll whisk together the wet ingredients for the cake, sift in the cake mix and pudding mix, and pour the batter into the cake pans. Bake the cakes for 20-25 minutes and then allow them to cool before wrapping them in plastic wrap and chilling them in the fridge.

While the cakes are chilling, you’ll make the key lime buttercream by whipping softened butter with sweetened condensed milk, vanilla, and key lime flavoring. Once the cakes are chilled, you’ll assemble and decorate them by piping the buttercream onto the layers, garnishing it with lime slices and LorAnn’s homemade Key Lime flavored gummy bears.

A: Yes, you can. However, keep in mind that the Super-Strength Flavors are more potent than the Naturals, so adjust the amount used accordingly.
