Fruit Pebbles Cake – Fruity Pebbles infused cake layers, with a Fruity Pebbles filling and vanilla buttercream.
I’ve had this Fruity Pebbles cake on my mind since trying the Fruity Pebbles macaron ice cream sandwich from Perfect Scoop in Las Vegas last month. I was obsessed with how well they incorporated the cereal flavor into the cookie and the ice cream without just throwing in pieces of the cereal. The flavor was a part of every bite and that’s exactly what I wanted for this cake.
Trial and Error
In my first round, I used ground up cereal in place of some of the flour in the cake. It created a great flavor to the cake, but the texture was all wrong! It was too dense and fell apart really easily. I was disappointed, of course, but kept going. As I thought about how to get the Fruity Pebbles flavor into the cake, I remembered that Milk Bar has something they call “Cereal Milk.” Milk Bar creator, Christina Tosi, originally came up with this idea for a cereal panna cotta. Cereal Milk is made by soaking cereal in milk for about 20 minutes and then strain the milk. The milk remains smooth but there’s now a fabulous cereal flavor to it.
That’s exactly what I needed for this cake and it worked beautifully. With the Fruity Pebbles milk, you get a great Fruity Pebbles flavor in the cake (not too strong) and still have a fluffy, moist cake.
While I was thinking about Milk Bar, I also decided to use their cereal crunch element for this cake to add some texture to the layers. The cake is certainly a sweet one, so the added kosher salt in the crunch provides a bit of a balance.
And not one to stop there, I also wanted the filling to be flavored with Fruity Pebbles, so I ground up some more cereal and added it to my vanilla frosting. I love how it adds just one more touch of the cereal flavor and is a slightly different texture than the frosting itself. It does thicken slightly with the cereal crumbs in it.
So now with Fruity Pebbles cake layers, Fruity Pebbles filling and cereal crunch, and a whipped vanilla buttercream, this cake shouts Fruity Pebbles with every bite. It’s definitely on the sweeter side but I wouldn’t want it any other way!
