    Loved the crust. Made it with brown sugar. The filling wasn't very tasty. Added lime juice which helped a little. Will add more next time I make it. My family loved it as is and ate all of it.

    Love this pie. It tastes great and only takes 10 minutes to make. Sometimes I just make the filling and sprinkle crushed graham crackers over it.

    Love this easy, flavorful, summer recipe! If you are a key lime pie snob, it’s obvious from the ingredients that it is not going to be “true “ key lime pie; however, call it creamy lime flavored pie! Either way, mine came out delicious and it is great to serve on a warm summer evening. I used Chabani key lime flavored yogurt, just because I love the flavor of this yogurt by itself! Stick it in the freezer for about an hour before serving, and it’s like eating an ice cream pie! Yummy!

    I made it, and it tasted great, however a package of knox gelatin was needed to make it firm. Today instead of Key Lime, I made it with Strawberries. Excellent!

    This pie is super easy! You can also change up the flavor just by changing the Yogurt

    This is absolutely the WORST Key Lime pie I have ever tasted. Maybe it's because I am a native Floridian but this is terrible. No one in my family would eat it and I had to throw it away. I made it on a trip to St Louis because I couldn't get key lime juice, but it was a waste of time and money. Disgusting. By the way, Key Lime pie is NEVER green. If it's green, it's not the real thing.

    I added juice from 1/4 of a large lime at the end and folded that in as well. Best key lime pie ever!

    Great recipe! I have made this pie twice. The first time, I made as key lime and the second time, I used strawberry gelatin and strawberry yogurt and they were both delicious! Our guests really enjoyed these pies. I am thinking of trying orange next! So quick and easy :)

    I've been making this one for years. Hard to believe it's so easy and yet so delicious! I use sugar free gelatin and light whipped topping.. I've also made it with lemon gelatin and lemon yogurt. Sometimes I make it in an 8 x 8 square pan using just some graham cracker crumbs on the bottom instead of a crust to cut down on carbs. That way I get 9 servings instead of 8.
