Instructions

Preheat oven to 350 degrees F.
In the bowl of a stand mixer, add the room temperature butter and sugar. Cream, using the paddle attachment, until light and fluffy—about 1-2 minutes. Next, add the egg, lemon juice, and lemon zest—scraping down the bowl as needed.
Finally, whisk together the flour, baking powder, and salt in a separate bowl, then add to the butter mixture. Mix on low speed until well incorporated and no streaks of butter remain, but do not overmix.
Line a 9" x 9" baking sheet with parchment paper, or lightly spray with nonstick cooking spray. Press the cookie dough into the prepared baking pan, covering the bottom of the pan as evenly as possible.
Bake in your preheated oven for 20-25 minutes, or until just barely golden on the edges. Remove from the oven and let cool slightly.
Meanwhile, in the bowl of a stand mixer, cream together the room temperature butter and 1/2 cup powdered sugar until light and fluffy. Add the remaining powdered sugar and lemon juice and mix again. You want your icing to be spreadable, so adjust by adding a little more lemon juice or powdered sugar as necessary. If desired, mix in 2-3 drops of yellow food coloring.
Using an offset spatula, spread the lemon icing over the warm lemon blondies evenly and to the edges. Let the cookie bars cool completely before cutting into 9 even squares. Enjoy!

Notes

Storing instructions: wrap or store in an airtight container in the fridge for up to 3 days. Blondies without icing can be wrapped well with plastic wrap and then stored for up to 2 months in the freezer. To thaw, transfer to the fridge overnight or room temperature for about an hour. From there, you can frost them and serve.
