Ingredients

Sugar Cookie Bars

  • 1 cup unsalted butter, room temperature
  • 1 cup granulated sugar
  • ½ cup light brown sugar
  • 1 tbsp lemon zest
  • 2 large eggs, room temperature
  • 1 tsp lemon juice
  • ½ tsp almond extract, optional
  • 2 cups all-purpose flour
  • ½ tsp baking powder
  • ½ tsp kosher salt

Lemon Buttercream

  • ½ cup unsalted butter, room temperature
  • 2 cups powdered sugar
  • 2 tsp lemon juice
  • ½ tsp almond extract, optional
  • toasted sliced almonds, optional

Instructions

Sugar Cookie Bars

  1. Use a stand or hand mixer to blend softened butter, brown sugar, and granulated sugar until smooth.
  2. Add eggs, lemon juice, lemon zest, and almond extract. Beat until the mixture is light and fluffy (approx 3-5 minutes).
  3. Add flour, baking powder, and salt. Mix until everything is well combined; the dough should be wet and sticky.
  4. Cut a parchment paper sling slightly smaller than the cake pan’s width. Spray the pan with a vegetable oil-based spray, place the sling inside, and secure it with metal binder clips.
  5. Scoop the dough into the pan, press it down evenly, and refrigerate for around 15-20 minutes to firm up.
  6. Preheat the oven to 350°F while the blondies chill.
  7. Bake at 350°F for approx 30-35 minutes until the top is golden brown and a toothpick comes out mostly clean.
  8. Let the blondies cool fully in the pan, then use the parchment paper edges to slide them out.

Lemon Buttercream

  1. Use a stand mixer with the paddle attachment to blend softened butter and powdered sugar until smooth and creamy.
  2. Add lemon juice and almond extract. Beat the buttercream on high for 4 minutes until it’s light and fluffy.
  3. Once the lemon blondies have cooled completely, place dollops of the lemon frosting on top. Gently smooth it out evenly and create swirls with the back of a spoon.
  4. If you like, sprinkle toasted sliced almonds on the lemon sugar cookie bars!

Notes

  • It’s better to slightly undercook the blondies than to overcook them. Blondies can dry out quickly, so it’s safer to be cautious when baking.
  • Bake them until a toothpick inserted in the center comes out mostly clean but still a bit gooey. If you’re uncertain, take them out, as they’ll firm up more as they cool. Note: If the pan is larger, the blondies will take less time to cook.
