# What You Need:

→ Cookie Base

01 - 2 1/4 cups all-purpose flour
02 - 1/2 teaspoon baking powder
03 - 1/4 teaspoon salt
04 - 1/2 cup unsalted butter, softened
05 - 1 cup granulated sugar
06 - 2 large eggs
07 - 2 teaspoons vanilla extract
08 - 1/4 cup whole milk

12 - 1 teaspoon vanilla extract
13 - Green food coloring

→ Decoration

14 - Shamrock-shaped sprinkles or green sanding sugar (optional)

# How to Make It:

01 - Preheat oven to 350°F. Line a 9x13-inch baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
03 - In a large bowl, beat butter and sugar with an electric mixer until light and fluffy, about 2–3 minutes.
04 - Add eggs one at a time, beating until combined. Mix in vanilla extract.
05 - Gradually add flour mixture, alternating with milk, beating on low speed until just combined.
06 - Spread dough evenly into the prepared pan.
07 - Bake for 18–20 minutes, or until edges are lightly golden and a toothpick inserted in the center comes out clean. Do not overbake.
08 - Cool completely in the pan on a wire rack.
09 - Beat butter until creamy. Gradually add powdered sugar, milk, and vanilla, beating until smooth and fluffy. Add green food coloring, a few drops at a time, until desired shade is reached.
10 - Spread frosting evenly over cooled cookie base. Decorate with shamrock sprinkles or green sanding sugar if desired.
11 - Lift out of the pan using parchment overhang and cut into bars.

# Expert Tips:

01 -
  • These bars come together faster than individual cookies but taste just as buttery and sweet
  • The soft, cake-like texture paired with creamy frosting feels like a special treat
  • They are the perfect make-ahead dessert for St. Patricks Day parties
02 -
  • Overbaking will make these bars dry, so pull them out when just set
  • Completely cooled bars are essential or the frosting will melt and slide off
  • Gel food coloring gives more vibrant green color than liquid without thinning the frosting
03 -
  • Chill the frosted bars for 15 minutes before cutting for the cleanest edges
  • Try adding a pinch of almond extract to the frosting for a subtle flavor twist
