Monster Birthday Cake

First up and most important is the birthday cake. Create a small smash cake for the child that looks like a monster. Pipe frosting in spikes to look like crazy monster hair. Use fondant to make an eye and a mouth. Attach them to the cake using buttercream. Make sure to refrigerate so the frosting sets, keeping your decorated cake together. Little ones will love digging their fingers into a fun and colorful monster birthday cake! If you are having a virtual birthday party, you can show the first bite on camera for friends and family to witness.


Monster Fruit Bowl

This easy appetizer will look like a monster is gobbling up the fruit! Cut a watermelon in half, dig out the inside, and cut the edge to look like teeth. Put a blueberry over a lemon slice and attach it to the watermelon using a toothpick. Do the same on the other side and you have monster eyes! Stick fruit kabobs into the head for hair, and fill the “mouth” with fruit that spills onto a plate. Kids will love this hilarious treat!


Spaghetti Monster

Look out for the slippery tentacles…it’s the spaghetti monster! This birthday party entrée turns a classic Italian favorite into a monstrous meal.
