This Funfetti Sheet Cake is decadently moist and packed full of rainbow sprinkles!

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 buttercream, or maybe even the best chocolate buttercream recipe!

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

    I grew up eating funfetti cakes made from a box mix on my birthday so this type of cake already provide a nostalgic type of enjoyment for me. But, this cake is ACTUALLY delicious even without the nostalgia. I love how the bit of almond extract gives it a full flavor.

    The sour cream in this sheet cake gives it such a moist, delicious texture! Such a tasty dessert and of course, kiddos loved it!
