Retro-Style Chocolate Sheet Cake. I’m taking us back a bit in time with this delicious fudgy chocolate sheet cake. Picture a flavorful, light, and fluffy chocolate sheet cake with rich chocolate flavor. Then add the most delectable, roll your eyes back good, chocolate frosting that’s sweet and fudgy. This cake is naturally gluten-free and takes so little effort to make. It’s extra chocolatey and every last bite is truly delicious.

I’ve always wanted to make a simple chocolate sheet cake. But that was just it, it felt too simple and basic to share with you all. I know that sounds kind of silly, but I like to share more unique recipes with you guys. My hopes are that I will inspire you to create something fun to cook up for dinner or dessert.

To this day, I haven’t shared a super classic chocolate sheet cake. Maybe someday I will, but honestly, I love this cake even more. It’s classic…but better.

I’ve been thinking back to the recipes our moms and grandmas would bake up and the sweets we enjoyed as kids. Rich chocolate peanut butter bars and sweet sheet cakes for birthday parties. To me, the peanut bars were delicious, but the sheet cakes always lacked a bit in flavor. Probably because most of them were store bought or box cakes.

I got to thinking about how I could still make a retro-inspired sheet cake, but still improve upon it a bit. I wanted to give the cake more flavor, make it less sweet, and figure out a better frosting that didn’t just taste like lots of sugar.

So then I played around with this cake, using almond flour, and maple to sweet things. And adding coffee to really pull out and highlight the chocolate. It ended up being so wonderful, and I love that it’s a bit more wholesome too.

The cake details

Nothing fancy here, just mix the wet ingredients with the dry and simply bake the cake in a baking dish. One bowl – nothing complicated. As mentioned, I used almond flour for this cake, so it’s naturally gluten-free.

And then, I used maple syrup as the sweetener, which I really love. Cakes are, of course, delicious, but I hate the “sugar” headache you can get when they’re overly sweet. Don’t worry though, this is still plenty sweet!

The frosting

While the cake itself is on the more wholesome side, the frosting is a tried and true retro-style classic.

The frosting needed to be thick and fudgy, but yet soft and almost runny. Think of a just set top that has glazed over and stiffened, but underneath is fudgy, loose frosting.

Very old school, very vintage, which is exactly what I was going for. Just like the kind of frosting your grandma would make.

Once the cake has cooled, simply spread the frosting over top and that’s it, easy.

You can let the frosting set up or just cut in and enjoy!
