This Easy Halloween Bundt Cake is perfect for a Halloween party or a fun treat to serve your family. Not only is the brownie bundt cake super easy to make but it takes absolutely no special decorating skills.
When my kids were young it was the first thing I added to the Halloween dessert table for our annual pre-trick or treat party.

READER REVIEW: Bailey says, “I have never decorated a cake before and was nervous but it was so simple to do that I even let my 5 year old help.” ⭐️⭐️⭐️⭐️⭐️

What goes into this Recipe

- Chocolate Frosting– Remove the foil top and microwave to get a quick glaze. I use the same technique for the top of this Black Bottom Bundt Cake.
- Rice Krispie Treats– Straight from the snack aisle, they work as the anchor in the middle of the bundt cake. If you prefer to make your own, this Chocolate Rice Krispie Treat would work wonderfully.
- Oreo Cookie Crumbs– You can make them by smashing cookies in a zipper bag with a rolling pin. If you don’t have time you can find Graham Cracker Crumbs in the baking section of the grocery store as an alternative.
- Pumpkin Candies– I have added them whole but you could also add half candy pumpkins to the top of the cake. Halloween sprinkles would also be great on top of the easy dessert.
- Ghost Marshmallow Peeps– Peeps are not just for Easter anymore! Now you can find white ghosts.

Variations
Of course, you can mix and match the decorations with whatever fun Halloween goodies you find at the grocery store, but the real variations will come from changing up the cake you use as a base.
Try some of these bundt cake recipes {made with a cake mix} for a twist on the flavor:
- Candy Corn Cake, this cake would be super fun because cake batter is baked in a striping pattern {like a candy corn}. You divide the batter between a few separate bowls and use food coloring to get both an orange batter and yellow batter.
- Peanut Butter Bundt Cake
- Cookie Butter Bundt Cake
- Snickerdoodle Bundt Cake
How to make an Easy Halloween Bundt Cake
- Begin by placing your cooled brownie bundt cake onto a serving plate. Then microwave the frosting until pourable and drizzling over the cake {you won’t use all of the frosting}. Cut the Krispie Treats and place them into the center of the cake to fit.
- Use some of the remaining frosting to cover the Krispie treats and any other areas you might want more frosting for the first layer.

- Add the crushed Oreo crumbs to the middle of the cake {on top of the frosting covered Krispie treats}.
- Add the ghost peeps that you have put on skewers {or inserted toothpick} into the middle of the cake, making sure they are secure in the Krispie treats. Add candy pumpkins on top of the cake and around the edge of the cake.

Expert Tips
- Cut the Rice Krispie Treats down so that they fit into the middle of this festive Halloween bundt cake. Adding them whole could make the middle of the cake tear.
- Make sure to microwave the frosting for only 15 second increments. If you microwave it too much it will become like water and not become a glaze like you want it to be.
- Want a darker frosting? Add a bit of black gel food coloring. This will give you a deep black frosting.
- Can’t find Ghost Peeps? Use Reese’s Peanut Butter Pumpkins or make a few Brownie Bats for the top of the cake.
Storage and Freezing
Store– Wrap your Halloween Bundt Cake in plastic wrap and then store it in the refrigerator. It will stay moist for up to 4 days.
Freeze– To freeze a bundt cake, wrap it in plastic wrap and then in foil. The cake will stay fresh for up to 3 months.
Recipe FAQs
Yes! If you have a frosting or glaze recipe that you prefer then go ahead and use that. It can either be microwaved and poured over the top of the cake or you can smooth it on with a spatula.
Try using this homemade cream cheese frosting or cookies and cream frosting, both would work great!
A bundt cake pan is important for this cake because we are using the hole in the middle to hide the Rice Krispie treats. The Krispie Treats are important because they are holding the ghosts in place.
A 12-cup tube cake pan would also work if you have one.

Easy Halloween Bundt Cake
Ingredients
Brownie Bundt Cake
- 1 box chocolate cake mix, {15.25 ounces}
- 1 box chocolate fudge brownie mix, {18.3 ounces}
- 4 large eggs
- 1 ¼ cups water
- 1 cup vegetable oil
- ¼ cup sour cream
Toppings/Decorating Items
- 1 tub chocolate frosting, {16 ounces}
- 2 Rice Krispie Treats
- ½ cup Oreo cookie crumbs
- 15 pumpkin candies
- 3 ghost Peeps
Instructions
- Preheat the oven to 350°.
Brownie Bundt Cake
- In a large bowl combine the cake and brownie mixes. Whisk them together until evenly combined. To the mixes add eggs, water, oil and sour cream. Use a hand held {or by hand} mixer to mix the ingredients together until you have a nice smooth cake batter.
- Spray your bundt pan with nonstick cooking spray and pour the cake batter into the pan. Bake for 50-60 minutes or until a toothpick inserted in the center comes out with only a few crumbs {not any raw batter}. Place the cake on a cooling rack and allow the cake to cool for at least 10 minutes.
- After 10 minutes, use a knife {or skewer} to run along the edge of the cake and loosen up any areas that may have stuck. Turn the cake out onto a cake plate and allow the cake to continue to cool.
Decorating
- Once the cake is cool, cut the two Rice Krispie Treats down and place them into the middle of the bundt cake. Note: Fill the middle of the bundt cake.
- Now take the frosting and remove the foil top completely. Place the frosting in the microwave for 15 seconds and stir. Continue 10 second intervals until the frosting is pourable but not liquid. Pour it over the top of the cake {even over the middle, covering the top of the Krispie Treats}. Note: It may not take the entire can of frosting.
- Pour the Oreo cookie crumbs over the top of the cake, keeping them in the middle area. You want to cover where the cake and Krispie Treats meet on the edges. Place three ghost Peeps onto a skewer {cut it down if needed} and dunk the bottom of the skewer in the frosting before placing into the middle of the cake. I like to offset them but you can place them however you prefer as long as it is in the Krispie treat area. Add the candy pumpkins around the skewers and around the edge of the cake. Serve and enjoy.
Notes
- Make sure to microwave the frosting for only 15-second increments. If you microwave it too much, it will become like water and not become a glaze like you want it to be.
- Wrap your Halloween Bundt Cake in plastic wrap and then store it in the refrigerator for up to 4 days.
- To freeze a bundt cake, wrap it in plastic wrap and then in foil. The cake will stay fresh for up to 3 months.
