Spookiest Halloween Dirt Cake Recipe

This Halloween Dirt Cake Recipe is the star of our Halloween celebrations. It’s rich and chocolatey, and very, very silly.

It’s Halloween Baking Month!!!

Guys! It’s that time of year. Halloween is coming. Do you know what the best thing about Halloween is (other than pets in totally ridiculous costumes)? Halloween Desserts! We’ve been stockpiling recipes all year and we’re kicking off October (aka Halloween Month) with a very special graveyard theme dirt cake.

A slightly non traditional Halloween Dirt Cake Recipe

As you’ll see, this cake is a little bit different from a traditional dirt cake. Shockingly, it actually is what it says it is. We like to use our favorite dark chocolate cake, topped with our fudgy chocolate icing, so it’s definitely not no-bake. From there, it’s all about the decorations, starting with the oreo crumbs standing in (obviously) for the graveyard dirt. Then, it’s all on you to find the creepiest Halloween candies on the market! We’ve recommended some below, should you need some help.

Halloween Dirt Cake Recipe Tips

This was the perfect addition to our Halloween party. Our kids thought the gummy body parts were hilarious and probably enjoyed eating them at least as much as the cake itself. It was a very fun treat. We made this as an 8 x 8 inch square, but you could easily make individual servings of this graveyard dirt cake in a clear plastic cup. As a reminder, should you be facing a busy Halloween season (aka should you need to bake obsessively every day for the next 31 days), this chocolate cake keeps extremely well wrapped in plastic wrap in the freezer and defrosts quickly in the refrigerator.
