Every year, I try to bake at least one Halloween-themed treat for my kids. In my house, we love the cookie spiders, cookie ghosts, and dirt cake with gummy worms, though let’s be honest—my children love anything sweet. This year, we were inspired to make a Halloween cake with a secret message. It’s a cinch to make this boo cake, and your kids will love the surprise message when cutting into this cake. We chose ‘BOO’ for Halloween but the possibilities for this secret message cake are endless; choose your child’s name or initials for their birthday, or celebrate other holidays with short, secret messages baked right in.

Supplies:

  • one batch of white cake batter
  • black edible dough
  • small letter cutters
  • wax paper for working on
  • rolling pin
  • 9×5 loaf pan, generously greased with baking spray (for the BOO cake)
  • small loaf pan, generously greased with baking spray (to make an additional, regular smaller cake from the leftover batter)

Instructions:

Step 1: The edible dough must be softened before use. Do this by taking small sections of the dough and kneading it between your fingers until it has softened. Continue until all the dough is soft.

Step 2: Roll out the softened dough to between ⅛” and ¼” thickness and cut out letters.

Step 3: Once all the letters have been cut out, add enough batter to the bottom of the loaf pan just to cover the bottom.

Step 4: Then, begin setting your letters, upright, in the pan. Repeat the word over and over, for the length of the pan, leaving about ½” between

Step 5: Gently spoon batter on top of the letters until they are covered, and fill the pan until it is ⅔ full. Use any leftover batter in the small loaf pan, repeating steps 3 through 5, to bake the rest of the batter up (why waste it?).

Step 6: Bake the 9×5 loaf pan at 350 F for 40 to 45 minutes, until a toothpick inserted in the cake comes out clean. For the small loaf ban, bake at 350 F for approximately 15 minutes, until a toothpick inserted in the cake comes out clean as well.

Step 7: Allow the cakes to cool. Frost as desired and slice using a sharp knife.

And Boo! to you. Happy Halloween.
