If you love the taste of a tart and tangy key lime pie, you’re going to love this Key Lime Pie Fudge. It’s a buttery, homemade graham cracker crust, topped with the delicious smooth texture of key-lime flavored fudge. It’s one of our new favorites!
We originally saw a delicious Key Lime Pie Fudge pinned on Pinterest and it seriously looked amazing. We were so excited to get the recipe so we could make it ourselves, but when we clicked on the link, it took us to a store that sells the fudge. There was no recipe in sight.
We made it our mission to find a recipe so that we could make this fudge ourselves. We googled it and found a couple of recipes, then combined them and came up with this.

Equipment Needed
For this recipe, you only need a few simple kitchen tools. We recommend using the following equipment:
How to make Key Lime Pie Fudge
Graham Cracker Crust
- Line an 8×8″ pan with wax paper.
- Mix together graham cracker crumbs, 1/4 cup sugar, melted butter or margarine in a bowl until well blended. Press mixture into prepared pan.
- Bake at 375℉ for 7 minutes. Cool completely.
Key Lime Filling
- Combine the milk, 1 ⅔ sugar and salt in a large, heavy saucepan and cook over medium heat until mixture comes to a boil; stirring constantly. Once mixture begins to boil, cook it for 8 minutes, stirring constantly.
- Remove from heat and stir in the marshmallows, chocolate, food coloring, lime rind and lime and mix well until mixture is melted and smooth. Pour into prepared pan and cool completely. Cut into 1 inch squares to serve.
Storing and Other Tips
Keep in an airtight container on the counter (do not refrigerate) for up to 3 days.
I’ve made this recipe multiple times, and depending on my altitude and humidity, the time I need to cook it for changes. Closer to sea level in California, I’ve found the best results when cooking the mixture for 6 minutes after it starts to boil.
If you’re worried about your quality of chocolate, or your chocolate seizing up, I would add in everything else before adding in the chocolate. That way, the mixture cools off just a little bit, but it’s still more than warm enough to melt the chocolate.
Be sure to add in the food coloring slowly. One drop, then mix it to see what color it produces. You can always add more green, but you can’t un-add food coloring! The second time I made this I went a little heavy-handed on the coloring and ended up with almost a chartreuse color (it still tasted good, but it wasn’t the prettiest).
Homemade Graham Cracker Crust
One of the tastiest parts of this recipe is the homemade graham cracker crust bottom. You only need 3 ingredients (sugar, graham cracker crumbs, and butter) to make it.
You can always crush your own graham crackers to make crumbs – using a plastic bag and a rolling pin or a food processor – or you can use our little cheater method: store bought graham cracker crumbs.
