INGREDIENT NOTES & SUBSTITUTIONS
Mini Sheet Cakes: I used the Chantilly Cream Vanilla Bean cake for this recipe because it’s available year -round, but feel free to use any flavor you like. This “recipe” is incredibly flexible.
Decorations and embellishments: You can never go wrong with fresh fruit and mint, but again, sky’s the limit! Some other ideas include: sprinkles, chocolate shavings, edible flowers, candies, nuts, coconut, and this delicious strawberry crunch topping!


Casey’s Top Tip: Place small pieces of parchment paper under the cake while you are frosting it with the whipped cream frosting. When you’re done, gently pull the pieces of parchment out from under the cake for a completely clean serving plate. I learned this trick from Ina Garten!
