These bars are full of lime and margarita flavor! There's a burst of citrus in the filling and a sweet crunch from the graham cracker crust.
1 1/2cupsgraham cracker crumbs
7tablespoonsunsalted butter— melted (no substitutions - use REAL butter)
2 1/4cupgranulated sugar— divided
1/3cupfresh lime juice— from about 5-6 limes
1tablespoonfresh orange juice
1tablespoontequila— optional (you can omit and use an extra tablespoon lime or orange juice instead)
1/4cupall purpose flour
Powdered sugar— for dusting
Preheat oven to 350°F. Line a 9x9 square pan with foil or parchment paper and spray with cooking spray.
Mix crumbs, 1/4 cup sugar, and melted butter with a fork 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.
While the crust is baking, prepare the filling. Whisk the eggs with remaining 2 cups of sugar. Whisk in juices, zest, and tequila, then whisk in flour until no lumps remain.
Note: you can omit the tequila if you wish. Use an extra tablespoon of orange or lime juice in it’s place.
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.
