Step 1

Preheat oven to 350°Line a 9x9 square pan with parchment paper and spray with cooking spray.

Step 2

Mix crushed pretzels, 1/4 cup sugar, and melted butter with in a large bowl. Press into the bottom of the prepared pan. Be sure to compact it very well. Any little holes in the crust will cause the filling to leak through. Bake for 12 minutes.

Step 3

While the crust is baking, prepare the filling. Whisk the eggs with remaining 2 cups of sugar. Whisk in lime juice, zest, and tequila, then whisk in flour until smooth and no lumps remain.

Step 4

Pour lime mixture slowly and carefully over hot crust then continue baking for about 25 minutes until the top starts to brown and is no longer translucent. Cool bars completely before cutting. It’s easiest to cut cold bars, so I suggest chilling them before cutting. Dust the tops with powdered sugar. Store in refrigerator for up to 3 days.
