For the Bar Base

1 cup unsalted butter, softened
1 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
2 ½ cups all-purpose flour
1 teaspoon baking powder
½ teaspoon salt

For the Lemon Frost

1 cup powdered sugar
2 tablespoons fresh lemon juice
1 tablespoon lemon zest
2 tablespoons unsalted butter, softened
½ cup white chocolate, melted

Instructions

Step 1: Preheat Oven and Prepare Pan

Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving overhang for easy removal. Lightly grease the parchment paper.

Step 2: Make the Bar Base

In a large bowl, cream together softened butter and sugar until light and fluffy. Beat in the eggs, one at a time, followed by the vanilla extract.

Step 3: Combine Dry Ingredients

In a separate bowl, whisk together flour, baking powder, and salt. Gradually mix the dry ingredients into the wet ingredients until a soft dough forms.

Step 4: Bake the Base

Press the dough evenly into the prepared baking pan. Bake for 20–25 minutes, or until lightly golden and set in the center. Remove from oven and allow to cool completely before adding frosting.

Step 5: Prepare the Lemon Frosting

While the base cools, make the frosting. In a bowl, beat together softened butter, powdered sugar, lemon juice, and lemon zest until smooth and creamy. Fold in the melted white chocolate. Adjust consistency with more powdered sugar for thickness or a touch of milk for a thinner glaze.

Step 6: Frost the Bars

Spread the lemon frosting evenly over the cooled bar base. Smooth the top with a spatula. Optionally, garnish with extra lemon zest, white chocolate drizzle, or fresh berries.

Step 7: Chill and Serve

Place the frosted bars in the refrigerator for at least 30 minutes to set the frosting. Cut into squares or rectangles using a sharp knife for clean edges.

Notes

Ensure the bar base is completely cooled before adding frosting; otherwise, the frosting will melt and slide off. For extra smooth frosting, melt the white chocolate gently over a double boiler to prevent clumping.
