Ingredients

• 0.75 cup unsalted butter, melted
• 0.5 cup granulated sugar
• 1.5 cups all-purpose flour
• 1 tablespoon lemon zest
• 4 pieces large eggs
• 1.5 cups granulated sugar (for filling)
• 0.75 cup freshly squeezed lemon juice
• 0.25 cup all-purpose flour (for filling)
• 0.5 cup sour cream
• 2 tablespoons powdered sugar (for garnish)

Directions

Step 1

Preheat your oven to 350°F (175°C) and grease a 9x9-inch baking pan, then line it with parchment paper for easy removal.

Step 2

In a medium bowl, mix the melted butter and granulated sugar until fully combined. Add the 1.5 cups of flour and lemon zest, stirring until a dough forms.

Step 3

Press the dough evenly into the bottom of the prepared baking pan to form the cookie crust. Use the back of a spoon or your hands to smooth it out. Bake in the preheated oven for 15 minutes or until lightly golden. Remove and let cool while preparing the filling.

Step 4

In a large mixing bowl, whisk together the eggs, granulated sugar, lemon juice, and flour until smooth. Stir in the sour cream until fully incorporated. The filling will be slightly runny—this is normal.

Step 5

Pour the filling over the pre-baked crust, spreading it evenly across the surface with a spatula. Return the pan to the oven and bake for 20-22 minutes, or until the filling is set and slightly jiggly in the center.

Step 6

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

Step 7

Once chilled, carefully lift the bars out of the pan using the parchment paper. Dust the top with powdered sugar before slicing into 12 squares or bars.

Step 8

Serve chilled or at room temperature and enjoy Mama’s Lemon Sour Cookie Bars!
