I had this idea to make Key lime ice cream sandwiches and decided that the sandwich should be graham crackers. After all, that's the kind of crust you have with a Key lime pie. I scoured the internet for a recipe for graham crackers and made the recipe that was the most highly rated. I had to wait a week because I couldn't find graham flour and so I ordered some online. The flour came and I was excited to begin. After making the dough and refrigerating it, I rolled it out nice and thin and cut out round cookies, baked them, and set them aside while I made my ice cream. I made a simple no cook ice cream using sweetened condensed milk. Delicious!! Then I assembled them. Now came the moment of truth--the taste test. The ice cream was delicious. the graham crackers, however, were not. So disappointing. So what was going to be a 2 part post about homemade graham crackers and key lime ice cream has become a single post about key lime ice cream. Take my advice and don't waste your time making your own graham crackers. Buy the good old fashioned honey grahams and use those instead. here's what you'll need:
- store bought graham crackers
- 1 (14-ounce) can sweetened condensed milk
- 1 (5-ounce) can evaporated milk
- 2 tablespoons sugar
- 1 1/2 cups whole milk
- 1/4 tsp salt
- 1/4 C key lime juice (more if you like it tart)
Mix together the sweetened condensed milk, evaporated milk, whole milk, sugar, and salt. Stir in the lime juice and refrigerate the mixture at least 30 minutes.
Once the mixture is cold, pour it into your ice cream maker and freeze according to the manufacturers instructions.
Transfer into a container and freeze until hard.
When you're ready to assemble the sandwiches, place a scoop of the ice cream onto a piece of parchment paper and cover with another piece. With your hand, press down on the ice cream until the scoop is flattened. Place the ice cream on one cookie then top with another.
I wrapped these individually and put them in the freezer so that it would be easy to grab one whenever you want.
