I am probably the only American who took her sweet time getting on board the Funfetti train. I had a bad funfetti experience that, let’s just say, took the “fun” out of “funfetti”. 😂🚫🎉

BUT I’M HERE NOW!!!! Bring on the sprinkles! 

I think part of my initial sadness about funfetti cake was that it was all about the sprinkles, not the flavor. So, I decided to fix the flavor and then add sprinkles. What I bring you is the most fabulous vanilla cake with more than our fair share of rainbow sprinkles, because now that I am on this train, more is more! 

In addition, this funfetti sheet cake tastes like cake batter even when it is all baked up! Wait, hold up…

Yes, to emphasize, it is like the most delicious cake batter you’ve ever had that doesn’t lose even a minute amount of its glory once baked.

Lean in close now; I’m about to let you in on a little secret. In short, the secret to “cake batter” flavor is just a smidge of almond extract. 

You might be thinking, “Lindsey, please, I thought you were a pastry chef. You should know that vanilla cake is flavored with vanilla…🙄” And it *is*, but that “je ne sais quoi” in cake batter flavor is almond.

And in case the absolute best funfetti cake weren’t enough, I baked it in a rectangular cake pan for all the ease of sheet cake. I’d like to think that makes it extra fun! Or perhaps “Funfetti+”? Let’s make it a thing.

You can frost this funfetti sheet cake with a glorious lemon American buttercream like I did, or perhaps cream cheese, or maybe even the chocolate buttercream from these Death by Chocolate Cupcakes!

No matter how you ice it, it is already a party!

      Hi Janet! Using the 13×9″ pan is no problem, the cake will just be a tad thinner and I’d recommend you check on it a little earlier as it might be finished baking slightly faster. 🥳
