    This ooey gooey Slime Cake is as delicious as it is fun!

    Slimy Awesomeness Inside and Out!

    I used some McCormick Pure Lime extract and McCormick Neon food color to create the coolest “slime” you have ever seen! (Don’t worry, I will show you how easy it is to make… and how delicious it is to eat!)

    To make this cake you will need:

    1 box dark cake mix

    McCormick black food color

    6-inch round cake pans (3)

    chocolate buttercream recipe (below) using Special Dark Cocoa

    1 package vanilla instant pudding

    McCormick neon food color

    McCormick pure lime extract

    small offset spatula

    pastry bags

    rotating cake stand

    Being by preparing your chocolate cake. (You can definitely use a homemade chocolate cake if you prefer!) Add 1 teaspoon of black food color to the batter and mix to combine.

    Equally divide cake batter between three 6-inch round cake pans. Bake according to directions.

    Allow cakes to cool to room temperature and then level them so that they are all the same height.

    Prepare buttercream.

    • 1 1/2 c 340g butter, at room temperature
    • 4 c 500g powdered sugar
    • 3/4 c 94g DARK cocoa powder
    • 4 tbsp. 60ml heavy whipping cream
    • 2 tsp. 10ml McCormick Pure Vanilla Extract
    • pinch table salt
    • 1 teaspoons 5-10ml McCormick Black Food Color
    1. In the bowl of an electric stand mixer fitted with whisk attachment, whisk butter and sugar on medium high speed until very pale and fluffy or about five minutes.

    2. Be sure to stop at least once and scrape the bowl.
    3. With the mixer off, add in dark cocoa powder, vanilla and salt.
    4. Turn mixer on low and blend for about 30 seconds.
    5. One tablespoon at a time add in heavy cream.
    6. Once all cream has been added and mixture is mostly combined, turn off the mixer and scrape down the sides of the bowl.

    7. Add in 1 teaspoon of black food color.
    8. Now turn the mixer onto medium-high to high and whisk for 3-5 minutes or until mixture is lighter and fluffier. (Keep an eye on the buttercream. You may want to add another teaspoon of black food color to reach the desired depth of color.)

    9. The frosting will be shiny and seem to have many large air bubbles throughout and this is exactly what we are going for. (You can smooth those out on the cake if so desired.)

    Now prepare your “slime”. This has got to be the most fun part!! When I first had the idea to create this cake I could not image how to make an edible slime. My kids actually thought of using pudding! It’s the perfect texture and consistency!

    Green Slime Pudding

    Author: Amanda
    • 1 pkg vanilla instant pudding prepare according to package instructions
    • 1/2 tsp. McCormick Pure Lime Extract
    • 4 drops McCormick Neon Food Color
    1. Follow the instructions on the pudding box, adding the lime extract and food color to the mixture as you blend ingredients. Cover the mixture and place it in the refrigerator for at least an hour, or until you are ready to use it.

    Place some of your buttercream into a pastry bag.

    Set one layer of cake on cake stand or serving platter, then place that on top of your rotating cake stand.

    Pipe buttercream around the edge of the cake. This is essentially creating a “wall” or a “dam” to hold in the slime pudding.

    Add about 1/2 cup of slime pudding to the center and smooth out.

    Place another layer of cake on top and then pipe out another ring of buttercream around the edge of the cake. Fill will approximately 1/2 cup of slime pudding.

    Place final layer of cake on top. Use remaining buttercream to evenly cover the tops and sides of the cake. (You may have some frosting left over, just store in an airtight container in the refrigerator for up to 3 weeks.)

    Pour any remaining slime pudding over the top of the cake then chill until ready to serve. Best served within 24 hours of assembly and served chilled.

    PRO TIP: For an extra awesome “drip” down the sides of the cake, add your slime pudding to a pastry bag and cut off a small portion of the tip. Then just drizzle the pudding down the side in a controlled drip. Easy peasy!

    You literally are the queen of cakes. I happen to LOVE all things Halloween, and was looking for a Halloween dessert for a party I’m throwing…SO, this!

    Whoa this looks so cool! That green is awesome!

    Amanda this cake is so much fun and perfect for Halloween. I love the word slime ???? Another great creation and I bet your children loved this one xoxo

    Fun! What a great Halloween recipe!

    Oh lime extract? I love that. I had no idea it was a thing! Glad to find out it is!
    What a fun cake for Halloween!

    My boys would love this cake!

    SO FUN Amanda. You are my frosting favorite!

    This is so creative! My kiddos will get a kick out of this green slime! 😀

    Does the lime extract make it taste like lime? can i use something other than the lime extract?

      You can omit the lime extract if you want. It adds a bit of freshness to the overall recipe! 🙂

    What a seriously fun Halloween cake! The slime oozing everywhere is perfect! Love that your kids came up with the idea to use pudding!

    This cake looks like a great idea for Halloween, I can also add some decoration on top!

    I don’t have access to Lime extract is there a substitution I can use?

    I love all the colors! I use it just last night making chocolate candy flower suckers, it changed the texture of the white chocolate a little but I was able to use it on the flower petals and the different shapes in the flowers and it worked out great. I would recommend this product.

    I was wondering if the pudding went *funny* if not being eaten until 48 hours later?

    Can you use 9inch cake pans instead? Would just need to double up recipe?

    I made this recipe and when I put the slime on it didn’t have the same effect yours did. When I dripped it down the cake and put it in the fridge for later, it clumped and ran down the side of my cake. It looks like a mess and this is a cake order. Very disappointed

      If I were making a new recipe for a client I would be sure to test it first. In a situation like that, I would have instructed the client to pour the slime over either right before or AT the party… folks get a kick out of that kind of thing.

    What brand pudding did you use? I used jello instant vanill vanilla and it’s too translucent you can see the dark cake through it.

    Any football cake ideas

    best cake ever
