How to Make Key Lime Pie in the Slow Cooker

I had a twitter conversation (I know. I think it's a weird way to communicate, too...) with my friend Shirley a few weeks ago about Key Lime Pie. She wondered if I had a crockpot version, and that was pretty much all I needed to go about figuring out a way to make it.

This is the recipe that works! It uses sweetened condensed milk, which as we all know, is pretty much the nectar of the gods. Gosh, I love that stuff.

The Ingredients
serves about 8 if you're disciplined. Otherwise 4.


for the crust:
1 cup graham cracker crumbs (I use gluten free)
3 tablespoons melted salted butter
2 tablespoons brown sugar
1/2 teaspoon lime zest

for the filling:
2 large egg yolks
1 (14-ounce) can sweetened condensed milk
1/2 cup fresh lime juice (about 5 limes)
2 tablespoons fresh lemon juice (about 1 1/2 lemons)

to put into the crockpot (NOT the batter!!):
1 cup warm water

The Directions.

Use a 6-quart slow cooker with an inserted 1.5-quart casserole dish (like a Pyrex or Corningware). 
You are going to use the crcokpot as a bain-marie, or water bath. In a plastic bag, smash up the graham crackers to make crumbs. Mix the crumbs with the butter, brown sugar, and lime zest.
Press the crust mixture into the bottom of a casserole dish that you sprayed with cooking spray (I took a picture of the spray, but then forgot to use it. oops.)


In a large mixing bowl, use a handheld mixer or a stand mixer to whip the egg yolks, condensed milk, lime juice, and lemon juice together until it's frothy. Pour this evenly over the top of the graham cracker crumbs.

Pour 1 cup of warm water into the bottom of your slow cooker insert, then carefully lower in the baking dish, taking care to not slosh water into your pie.

Cover, and cook on high for 2 to 3 hours, or until the pie is no longer shiny on the edges and the center has set (poke it with your finger. You shouldn't get a bunch of goop on it).

Refrigerate for at least 4 hours (preferably overnight) before serving. If you'd like, you can add a layer of whipped cream on top.

The Verdict.

Yeah. This is good. I was ecstatic at how limey this turned out, and how nicely the sweetened condensed milk worked and set up beautifully in the slow cooker. I slightly overcooked one of the tester batches, but it still was fantastic -- the color on top just got a bit darker than I wanted it to, but after covering it with whipped cream nobody could tell.

Make this! You'll LOVE it!!
