Nicole at Baking Bites made these Slime-Filled Cupcakes from the Black Lagoon (click through for the recipe) and wrote:
I started out by making a batch of lime curd and using food coloring to give it a very bright green color, as lime curd on its own tends to be a fairly pale yellow. The curd needs to be made before the cupcakes so that it has time to cool and set up in the refrigerator before you use it. I think that lime is an appropriate slime flavor, but you could certainly dye lemon curd bright green, as well.
I used vanilla cupcakes as a base, hollowing them out via my usual method for filling cupcakes once they had cooled. The cupcakes were moist and not too sweet, which meant that the cake didn’t detract from the tartness of the filling, just balanced it out. I used a spoon to drop a dollop of lime “slime” into each hollow, as the curd flows much better than your average cream filling and does not need to be piped in.
