Ingredients

Instructions

  1. Step 1: Preheat the oven to 350°F. In a mixing bowl, combine 1 1/2 cups all-purpose flour and 1/2 cup powdered sugar. Cut in 3/4 cup cold unsalted butter cubes using a pastry cutter or fingers until the mixture resembles coarse crumbs.
  2. Step 2: Press the crust mixture evenly into a greased 8x8-inch baking pan. Bake for 15 minutes until lightly golden at the edges.
  3. Step 3: Meanwhile, whisk together 1 cup granulated sugar, 1/2 cup fresh lime juice, 2 large eggs, 1/2 tsp baking powder, 1/4 tsp kosher salt, and 1 tbsp lime zest until smooth.
  4. Step 4: Pour the lime filling over the hot crust and bake for an additional 18-20 minutes until the filling is set but still slightly jiggly in the center.
  5. Step 5: Remove from oven, sprinkle with a pinch of kosher salt, and cool completely before slicing into bars.

How long does Margarita-Inspired Lime Salt Bars take to make?

Total time is about 55 minutes (15 min prep + 40 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Margarita-Inspired Lime Salt Bars?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep all-purpose flour from drying out.

Can I substitute ingredients in Margarita-Inspired Lime Salt Bars?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Margarita-Inspired Lime Salt Bars for a different number of people?

The recipe is written for 9 servings. Multiply each ingredient by (your serving target / 9). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
