Unroll the pie crusts and gently break them apart at perforations.
Set one pie crust into each of the 12 muffin tin cavities and press to the bottom and sides. Poke holes in the bottom with a fork. Discard the remaining two pie crusts.
Bake for 10 to 12 minutes or until crusts are golden brown. Remove from the oven and allow to cool for 1 hour.
While the pie crusts are baking, boil ¼ cup of water in a saucepan over high heat. Add the lime gelatin and stir with a whisk until dissolved completely. Add the remaining ¼ cup water and stir for 2 additional minutes.
Refrigerate for 30 minutes.
Stir in the whipped topping. Then, refrigerate for an additional 30 minutes.
Add the mixture to a piping bag fitted with the 1M frosting tip and pipe the mixture into pie crusts. Sprinkle with lime zest.
Refrigerate for 1 hour, then serve.
Notes
Fresh lime zest makes all the difference in these key lime pie bites! It gives lots of bright flavors and adds beauty to these mini key lime pies. A microplane grater is the best way to zest limes and other citrus fruits. When zesting, remember to zest only the colored part and not the pith underneath.
Key limes can be hard to find, so I use regular limes for this key lime pie bites recipe. If you can’t find key limes, no need to worry, you can make this recipe with regular limes like I do or use key limes when they’re available.
