More About This Recipe
This surprise reveal cake can easily be personalized for any number birthday or occasion, and is easier to make than you'd think. With its size and scope it'll take you all day to create, but don't worry – most of that time is spent waiting for cakes to bake and cool. When you see your guests ooh and ahh over your cake, you’ll know it was totally worth it!
You'll be baking two separate cakes, starting with the tie-dye cake. To start, whip up two batches of the Betty Crocker Pound Cake Mix then divide the batter into several bowls and color each bowl using neon food coloring. I chose to make pink, yellow, orange, blue, and green, but you can do any colors you like.
Let your inner artist come through and drizzle layers of colored batter into a 16x4x4.5-inch loaf pan. I lined my pan with non-stick aluminum foil for easy removal, but you can grease it with shortening and dust it with flour if you prefer. Keep drizzling in colored batter until you use it all up. I found it easiest to put my batter into pastry bags and pipe it into the pan. You could use zip-top bags if you don't have pastry bags, or you could simply drizzle it with a spoon. There's really no right or wrong way to do this step. Bake the cake and allow it to cool completely. While it's cooling, clean out your pan and prep it the same way for your second cake.
Once the cake is cooled, cut it into slices that are just slightly thinner than your number cookie cutter (I used a 5). Pop the slices in the freezer for at least an hour, until they feel frozen and firm. Remove slices from freezer and cut one "5" out of each slice, then put them back into the freezer. You will have a lot of scraps, which could look really cool in a trifle or parfait, but they also make tasty little snacks just as they are.
While your numbers are chilling, whip up two more batches of cake mix and pour a thin layer of it into the prepped loaf pan. Put some of the batter into a large pastry bag or gallon-size zip-top bag
