Slime Filled Coconut Lime Halloween Cupcakes: Don’t be fooled by the creepy look of these cupcakes. They are delicious! Perfect for a kids Halloween party and an adult Halloween party. ALSO…how about a SHREK party!
Halloween is almost here and you know what that means. Yep, we take everyday food and make them scummy and gross. Aside from the name of these slime filled cupcakes with swamp scum frosting. All they really are is really good coconut lime cupcakes filled with lime curd. But the name makes them sound really cool.
Don’t have time to make lime curd? Don’t worry you can also used store bought just add food coloring to make it a slime green color. You can also use lemon curd. I really didn’t taste a difference between lemon or lime.
TIP: When coloring your “slime” and “swamp scum” use more yellow than green. A little green goes a long way. Add yellow first and then green.
Pour the lime curd into a zip top bag fitted over a cup.
Use a paring knife and allow out the center of each cupcake.
Fill with cooled lime curd.
Pipe frosting over the curd.
