Halloween Graveyard Brownie Cake
Growing up, I looked forward to Halloween all year, both for the costumes and the candy.
Butterfinger Peanut Butter Skulls are one of the coolest Halloween candies I’ve ever seen! The skull shape is perfect for creating creepy desserts, and is the inspiration for our Graveyard Cake.
It is similar to a brownie earthquake cake — the marshmallow swirl reminded me of fog swirling through a cemetery.
The addition of candy and cookie tombstones and Butterfinger Peanut Butter Skulls makes it all come together. Spooky and delicious!
I couldn’t help but snack on some of the Butterfinger Peanut Butter Skulls while baking our graveyard cake. I’m a big peanut butter fan, so these are right up my alley! The crispety, crunchety, peanut-buttery taste is the stuff cravings are made of — I’m pretty obsessed (and may or may not have bought like 5 bags).
What You Need to Make Graveyard Brownies
- Butterfinger Peanut Butter Skulls — or similar chocolate Halloween candy
- Brownie mix — We used two boxes of pre-made mix + the ingredients listed on the box
- Marshmallow fluff — May also be called marshmallow creme
- Oval shaped cookies and/or fun-sized Butterfinger candy bars — to be the tombstones
- Melting chocolate (optional) — We used both white and dark chocolate to draw details on our tombstones
Kitchen Tools Used
- 9 x 13″ baking dish
- Large mixing bowl
- Whisk & spatula
- Non-stick cooking spray
How to Make Graveyard Cake
Preheat your oven to 325°F and prep a 9×13″ baking dish by coating with non-stick cooking spray.
Note: Oven temperature may vary depending on the brownie mix you’re using. Follow package directions.
In a large mixing bowl, prepare brownie mix according to directions on package.
Pour half of the brownie batter into the baking dish and spread evenly. Layer with marshmallow fluff, then the rest of the brownie batter.
TIP: It’s ok if some of the marshmallow fluff peeks through the top layer of brownie batter. When it cooks, some of the fluff may come to the surface anyway, much like an earthquake cake.
Bake for about an hour and fifteen minutes.
TIP: Exact cooking time may vary depending on the type of brownie mix used and your particular oven. After 45 minutes in the oven, check your cake every 5-10 minutes by inserting a butter knife in the middle. If the knife comes out clean, your cake is done.
While brownie cake is baking, prepare your cookie and candy tombstones.
To make these, we simply dipped half of an oval-shaped cookie in melted white chocolate and allowed to set. You can also use regular Fun-Size Butterfinger can bars, as they are the perfect shape. You’ll want to make 4-8 tombstones.
Once the white chocolate is set, use melted dark chocolate chips and a toothpick to write spooky words like “RIP” or “BOO” on the front of each of your tombstones. Allow to dry.
When brownies are done baking, remove from oven and allow to cool completely.
When cake is cool, place your candy and cookie tombstones halfway into the cake, spreading them evenly around the cake.
Last, but definitely not least, it’s time to place Butterfinger Peanut Butter Skulls on your graveyard cake. We used toothpicks to keep them secure.
Can I Use Cream Cheese Instead of Marshmallow Creme?
We used marshmallow creme for our swirl because it’s super easy and doesn’t require mixing in any other ingredients.
However, if you’re not a fan of marshmallows, you can substitute cream cheese for a more traditional earthquake cake recipe.
- One 8oz block of cream cheese, softened
- 1/2 cup butter, softened
- 2 cups powdered sugar
Beat everything together until smooth, then swirl into the cake like you would the marshmallow fluff. Keep an eye while baking, as the cooking time may vary slightly since you’re using different ingredients.
A Note About Cooking Time
Since we’re using two boxes of brownie mix and adding marshmallow, this is a thick dessert! As such, it takes longer to cook than a normal brownie pan.
It took ours about an hour and a half to be set in the middle, but this could vary based on your oven temp and exactly how thick your cake is.
Keep an eye on your cake, starting at the 40 minute mark. If it looks wet in the middle, it’s probably still needing more time. If you’re unsure, do the knife in the middle test. If the knife comes out clean, take it out of the oven. If batter sticks to the knife, keep cooking.
