  • Pour batter into the prepared pans and bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.

  • Spread the cereal into a thin layer on a foil lined baking sheet. Refrigerate for 1 hour or until solid, then break or chop into small pieces.

  • Pour the warm cream over the chocolate. Let sit for 1 minute.
  • Whisk until glossy and smooth. Place plastic wrap on the ganache and refrigerate for 10 minutes.
  • Once pliable, whip on high speed with an electric hand mixer for 3-4 minutes until light and fluffy.

Assembly

  • Add a tablespoon of ganache to the middle of a cake board or stand and fan it out with an offset spatula. 
  • Place one cake layer on the board and spread an even layer of ganache over it.
  • Sprinkle ½ cup chocolate crunch on top. Place the second cake layer on top with the flat side up.
  • Spread a thin layer of frosting (crumb coat) all over the cake. Chill in the freezer for 20 minutes.
  • Apply a final layer of frosting. Pipe a boarder if desired and top with the remaining chocolate crunch. Slice and enjoy!

Notes

Measure the flour correctly in grams with a kitchen scale. If you don't have one, gently spoon the flour into your measuring cup and swipe off the excess.
Let the cake cool completely before frosting or the ganache will melt off.
Storage: Refrigerate leftovers in an airtight container for 3-5 days. Slice into individual pieces or store the whole cake in a cake carrier. Let sit on the counter for 30 minutes before enjoying.
Freezing: Freeze individual slices in an airtight container for up to 2 months. Let the slices thaw at room temperature for a couple hours before enjoying.
