Transform your favorite breakfast cereal into this delicious Froot Loops Cake! Vanilla cake layers infused with cereal milk.

Today’s post is an homage to my favorite cereal: Froot Loops. It was my favorite when I was little, and is still my fave to this day. Other cereals have come and gone, but none have had the staying power of good old Froot Loops. I don’t have it often, mind you. We try to keep the non-dessert meals around here somewhat healthy-ish, but there’s pretty much always guaranteed to be a box of this in our pantry, ready for those perfect Saturday mornings.

It’s one of those cereals that will completely rip up the inside of your mouth, but it’s totally worth it. I don’t like my cereal to get soggy, so it’s extra bad for that. On that note — are you an add milk to cereal or add cereal to milk kinda person? For me, always and forever, I pour milk in the bowl first and then sprinkle some cereal on top — but not too much for fear of it getting soggy (shudder). I add more cereal as I go, but I always make sure there are no stray Loops in the bowl before adding more.
I cannot understand how people pour a huge pile of cereal into their bowl and then pour the milk on top of that. Someone explain the rationale to me here! Just the thought of soggy cereal grosses me out.

While we’re talking sogginess here… it was not the smartest decision on my part to sprinkle chopped cereal between the layers. I was going to make a crumble, like in my Cinnamon Toast Crunch Cake, but I was worried that the color would look off, and I wanted it to look perfect and pretty. Well, it looks pretty, but the chewy cereal between the layers was not the best. It added more flavor, for sure, but if you opt to do this, I’d recommend making a crumble with it instead.

The Froot Loops on the outside of the cake stayed fairly crunchy for a couple days, but it would be best to serve this cake same day to avoid any potential mushy mishaps.

The cake layers themselves are made with cereal milk (milk that has had cereal steeped in it, kinda like what’s left over in your bowl after you finish eating — see recipe below). I also brushed the leftover cereal milk onto each of the baked layers during assembly to add both moisture and flavor.

Paired with a tangy cream cheese frosting that cuts down on some of the sweetness from the cake, this Froot Loops Cake is perfect if you have any die hard cereal fans in your life!
Tips for this Froot Loops Cake:
- You don’t have to use Froot Loops cereal, you can use any cereal you like to make this cake.
- I don’t recommend sprinkling cereal between the layers, as it will get soggy.
- If you want to amp up the flavor even more, you can crush up some cereal and add it right into the cake batter.
- To help ensure your cake layers bake up nice and flat, see my Flat Top Cakes post.

Use whole Froot Loops to decorate the sides of the cake and sprinkle chopped Froot Loops on top.**
Notes
** I do not recommend sprinkling chopped Froot Loops between the layers as I did as they will go soft very quickly.
