Ingredients

• 1 cup unsalted butter (melted)
• 1.5 cups all-purpose flour
• 1 cup granulated sugar (divided)
• 3 large eggs
• 0.5 cup fresh lemon juice
• 1 teaspoon lemon zest (optional)
• 2 tablespoons powdered sugar (for dusting)

Directions

Step 1

Grease an 8x8-inch microwave-safe baking dish with butter or cooking spray and set aside.

Step 2

In a medium bowl, mix 1 cup of melted butter, 1 cup of all-purpose flour, and 1/4 cup of granulated sugar to form a dough-like consistency for the crust.

Step 3

Press the crust mixture evenly into the bottom of the prepared baking dish.

Step 4

Microwave the crust on high for 2 minutes, or until it sets and starts to firm up. Set aside to cool slightly.

Step 5

In a separate bowl, whisk together the remaining 3/4 cup of granulated sugar, 3 eggs, 1/2 cup of lemon juice, and 1 teaspoon of lemon zest (if using).

Step 6

Add the remaining 1/2 cup of all-purpose flour to the lemon mixture and whisk until smooth and fully combined.

Step 7

Pour the lemon filling over the pre-cooked crust, spreading it evenly.

Step 8

Microwave the entire dish on medium power (50%) for 4 minutes, stopping to check at the 2-minute mark. The filling should be mostly set but slightly jiggly in the center.

Step 9

Allow the lemon bars to cool completely to room temperature, then refrigerate for at least 1 hour to fully set.

Step 10

Once chilled, dust the top with powdered sugar, cut into 9 squares, and serve.
