You’re in for a treat today! I have some of my best party planning tips for you along with a delicious Chocolate OREO Orange Fanta Cake. Yep, it’s amazing and perfect for Halloween. Since this is my FAVORITE holiday, I’m going to show you how to throw a Perfectly Spooky Halloween Party! I’m not a naturally organized person, but I’ve been creating parties for so long that I have this down to a science. ALL of my parties are budget friendly and you can put them together quickly, so you can easily recreate this party. The key? Do these three things a day or two (or three!) before the party:
Print and Cut Printables First
I really dislike cutting out printables. I love designing and putting them together, but cutting drives me crazy. That’s why I do this first. Pull off the bandaid and get it over with! Just keep in mind how many of each design you’ll need and cut out a couple extras just in case.
Prepare Food the Day Before
I make any food that I can the day before the party. I baked the cake, and made the whipped cream topping and Orange Fanta Slime topping the day before. I also made the OREO popcorn mix and spider web chocolate covered OREOs the day before.
Lay Everything Out
I always lay everything out before the party to make sure I have plenty of decor. I almost always switch things around right before the party, but I NEVER miss this step. I lay things out usually the day before. An added bonus is that it gets the kids really excited for the actual party.
Once I get those things out of the way, I can rest easy knowing the bulk of the work is done. This gives me time to get the house ready for guests (because it usually looks like hurricane Erin blew through the whole house when I’m party planning). The day of the party, I hung the banners and spider webs and decorated the cake.
I got the food for my OREO and Fanta treats and most of the decor at Walmart. I am usually a DIYer, but decor is getting so cute and inexpensive now, that I buy a lot of it. That skull gate in the background is my favorite thing ever. I lurve it.
I really like how this party doesn’t have the usual Halloween colors, but still looks spooky. Pink is scary, right? I thought so. The cake just makes this party and it’s SO good! I’m pretty proud of it because I don’t decorate cakes. This one is hard to mess up. Just pipe on the frosting, drizzle with Fanta “Slime” and top with Oreo crumbles.
Chocolate OREO Orange Fanta Slime Cake
Ingredients
- For the Cake
- 1 box Double Chocolate Cake Mix
- 1 1/2 c. Orange Fanta
- 1 egg white
- 6 crushed OREOS
- For the Whipped Topping
- 1 c. Whipping Cream
- 3 Tbs. sugar
- 1/2 c. Marshmallow cream
- For the Orange Fanta Slime
- 1 c. Orange Fanta
- 2 tsp. corn starch
Instructions
- Combine cake mix, orange fanta and egg white. Mix on medium until no longer lumpy.
- Add to greased baking pan, top with crushed OREOs, then bake according to cake mix instructions, then let cool.
- For the Orange slime, pour Orange Fanta into a small bowl, then whisk in corn starch.
- Heat a pan to medium heat, then add Fanta mixture.
- Turn up heat and bring to a boil, then turn heat down to low. Let it cook for about 1-2 minutes, stirring often until it thickens. Remove from heat and refrigerate.
- While cake and slime is cooling, whip whipping cream in a mixer until it starts forming peaks, for about 2-3 minutes. It needs to be stiff, but don't wait too long or it will turn to butter.
- Once it's thickened, add sugar and marshmallow cream and whip until combined.
- Pipe or spread whipped topping over cake, top with slime and more crushed OREOs and serve!

Jeannie @ For what it's worth says
I don’t like cutting out printables either, some day… I’ll get one of those die cutting thingies.
Erin says
I have one and sometimes I’m even too lazy to use that! lol
Elise says
Your creativity never ceases to amaze me! Another fabulous party! — and that CAKE!!! 🙂
Erin says
Thank you Elise! You are so sweet 🙂
Sandra Garth says
Love your party and I agree about buying some of the decor. Dollar Stores seem to be pulling out all of the stops these days with the decorations. The challenge for me is to not go crazy because everything is a $. Did I mention how much I love that cake?
Erin says
I know…dollar bins are so tempting! Thanks!!
Sunny says
Love this. The cake is genius, I can’t wait to try it. Love the bright colors and the not too creepy decor. You’re right that fence in the background is perfect.
Erin says
Thank you Sunny!
