Key Lime Bars

Recipe adapted from Joy The Baker. Yields one 9×13 inch pan, about 12 good-sized squares.

Preheat oven to 350ºF. Butter a 9×13-inch baking pan and set aside.

For the crust, in the bowl of a stand mixer cream the butter and sugars until fluffy, 3-5 minutes. Stop the mixer and scrape the sides of the bowl. Add the flour, salt and mint. Beat on low speed until the mixture just comes together.

Dump the crust mixture into the prepared pan and use your fingertips to spread it out evenly all over the base of the pan. Bake for 18-20 minutes, until slightly browned on top.

While the crust is baking, prepare the filling. In a medium bowl whisk together eggs and sugar until light and pale, about 8 minutes. Add the flour, lime juice, lime zest and green coloring. Whisk until completely blended.

Remove the baked base from the oven and immediately pour the filling mix over the hot crust. Return to the oven and bake for 20-25 minutes, until brown around the edges and set in the middle.

Cool completely in the pan. Cut into squares and dust with powdered sugar and more chopped mint. To store lime bars, place in an airtight container in the fridge for up to 4 days.
