Key Lime Pie with a Girl Scout Lemonade Pie Crust

It is the time of year again where I start craving pie. Odd for March huh, but the reason is a couple years ago we started making a fantastic key lime pie recipe using a secret ingredient. Now that it is Girl Scout cookie season, we can stock up on our secret ingredient and start making the best Key Lime Pie ever. This Key Lime Pie uses Girl Scout Lemonade cookies, the best Girl Scout cookie ever (sorry Thin Mints) as a base for our pie crust. It is fantastic! We love baking with Girl Scout Cookies.

Girl Scout Cookie Key Lime Pie

Our Girl Scout Key Lime-onade Pie, as our kids have started calling it, is super easy to make. It is also a fun and creative way to use some of the 42 boxes of Girl Scout cookies that you bought from the neighbor down the street. The most difficult part of the entire recipe may be trying to avoid eating a few cookies while you are making it.

Making the Girl Scout Key Lime Pie with Lemonade Cookie Crust

Making the Lemonade Cookie Crust

To make the crust for the pie you will need one 8.5 ounce package of Girl Scout Lemonades, 3 Graham crackers, and 6 tablespoons of butter. You will not need any sugar in the crust, because the frosting in the cookies provides plenty of sweetness.

Girl Scout Lemonade Cookies

As many of you are aware there are 2 companies that make Girl Scout cookies. We have not attempted this recipe with Girl Scout Lemon Ups, so if anyone tries it, be sure to let us know.

Girl Scout Lemonade Cookies

Place the Lemonades in a food processor, reserving 1 cookie for decorating.

Process the cookies until they are reduced to a fine powder. Add the Graham crackers and process, then add the melted butter and pulse to combine.

Once combined, press the mixture into the bottom of a pie dish. Spread evenly and up the sides of the pie dish. Your Girl Scout Lemonade cookie crust is complete!

Prepare the Key Lime Filling

Zest your key limes into a small bowl. If you cannot find key limes, you can substitute regular limes instead. You want a pretty fine zest, as long strands are not as appealing in the pie.

Key Lime Zest

Combine the sweetened condensed milk, sour cream, and key lime juice in a bowl. Mix thoroughly until combined and smooth.

Combine and stir the filling until smooth

Mix in 1 tablespoon of the lime zest, and stir until completely combined.

Bake the Girl Scout Cookie Key Lime Pie

Pour the key lime filling into the Lemonade cookie crust. Preheat an oven to 350 degrees.

Bake the pie for 12-15 minutes, turning halfway through. You do not want the pie to brown so keep an eye on it. When you begin to see tiny bubbles forming at the surface of the pie, it is done cooking. Remove the pie from the heat and cool at room temperature for about 15-20 minutes.

Rest the pie at room temp before refrigerating

After resting on the countertop, place the pie in the refrigerator and cool for at least 4 hours.

Making the Key Lime Whipped Cream Topping

The topping is best made and applied to the pie just before serving.

Combine the heavy whipping cream, powdered sugar, vanilla extract and a pinch of lime zest in a chilled bowl or mixer (using whisk/beaters that have also been chilled). Beat until stiff peaks are formed.

Whip the cream mixture until stiff

Top the pie with the whipped cream topping. Decorate as desired with limes, Girl Scout Cookies, or additional whipped cream.

    I am in Canada and we don't get many types of Girl Guide cookies. Chocolate, Vanilla and Mint is all. :-(

      I'm in Canada, and I found some lemon shortbread biscuits at the Dollartree. They have a thin hard icing on them. They might work for a substitution, or you could try some lemon zest in the graham crackers.

    We don’t have the scouts biscuits in Australia
