Just a Quick Note About the Recipe
Okay, so before I go annnnnny further with talking about this fabulous Easy Key Lime Pie recipe, I just want to put it out there that I used regular limes and not key limes.
Well, because trying to find these little gems where I live in Central PA proved to be a little challenging.
But I promise you this key lime pie is just as good!
Suggested Baking Tools and Tips for Making Key Lime Pie
Before starting this Easy Key Lime Pie recipe, give this list of suggested baking tools and tips a read!
- I used a 9" pie plate for this key lime pie recipe.
- If you don't have the Bahlsen Delice puff pastry twists available in your area, you can order them online or you can easily replace them with a different crust using graham crackers. I would recommend keeping the amounts the same.
- Likewise, if you have key limes readily available in your area, you can swap them out for the regular limes used in this recipe; however, you may need to use a few more key limes than what is noted to get the ½ cup of key lime juice and 2 teaspoons of lime zest.
- I baked the pie crust for 10 minutes at 350ºF and it came out perfect! After it's cooled, if you like, you can place it in the fridge to keep cool until the key lime pie filling is ready.
- After the pie has been baked, let it cool completely before serving. Alternatively, if you're not serving it right away, you can place it in the refrigerator to chill. This pie will keep in the refrigerator for about 3 days.
