- To make your monster cake, you’ll start by preheating the oven to 350 degrees.
- Spray your cake pans with nonstick cooking spray and set them aside.
- Next, you can make your cake batter. Make your green batter by adding the white cake mix, oil, water, and eggs to a mixing bowl.
- Beat the cake batter on medium speed until smooth.
- Add in the clear vanilla and beat for a minute to combine.
- Drop in 2-3 drops of electric green food coloring and beat the batter again until incorporated.
- Pour the batter into half of the pans and set them aside.
- Repeat the batter process with the black batter, using the chocolate cake mix and black food coloring, and pour it into the remaining pans.
- Bake the pans in the preheated oven for 30-40 minutes or until a skewer comes out clean when poked in the center of the pan.
- When they are baked, allow the cakes to cool in the pan for one hour.
- When the cakes are cooled, level the top of them with a knife and cut each layer in half if desired.
- Wrap each layer in plastic wrap and place them in the freezer for 2-3 hours.
- While the cakes freeze you should make your frosting by creaming the butter in a mixing bowl.
- Add in the powdered sugar and mix at low speed until it’s incorporated.
- Slowly pour in the heavy cream and vanilla or coffee creamer until you have a thick and creamy frosting.
- Mix the frosting at high speed for 10 minutes until it’s fluffy.
- Add in your desired color of gel food coloring and mix until combined.
- When the cake is chilled, start layering each layer with buttercream in between.
- Spread a thin layer of buttercream around the stacked cake and spread it evenly around.
- Using your circle cutters and a paring knife, cut out a large monster eye and mouth and press them onto the cake.
- Fill a piping bag with the remaining frosting and fit it with a piping tip.
- To pipe the fur, place the tip of the piping bag at the cake, squeeze, and while pulling away stop squeezing the bag.
- Make sure the whole cake is covered in fur except the facial features and your monster cake is ready to go!
Tips Tricks and FAQs
- If you decide to use flavored coffee creamer, you’ll want to omit the vanilla extract from the frosting when you are making it. The coffee creamer has plenty of flavor in it already and you don’t want to overpower your frosting!
- You can use 8-inch cake pans instead of 6-inch pans, but you will want to use 2 pans instead of 4 so that the batter is evenly distributed and can bake well. You can either split each layer in half to have 4 layers or you can keep each layer whole.
- Having circle cutters around is so handy, but if you don’t have any you can still cut out your fondant with cups you have in your kitchen. Just try to find some cups with comparably sized openings and use the opening to press into the fondant.
- Make sure that you are adding the food dye to the right batter. If you add black food coloring to a white cake it’ll only turn out grey. Similarly, the green will not turn out vibrant enough if it’s in anything but a white cake.
Storage
Store your cake in an airtight container in the fridge for up to 3-4 days. If you don’t have a cake stand with a lid this is the time to get one!
What should I do if my frosting is too loose?
If you find that your frosting is too thin, you can add more powdered sugar about ¼ cup at a time.
It should be thick enough that it should hold its shape when you are piping the fur onto the cake.
