Frosted Strawberry Cookie Bars

Frosted Strawberry Cookie Bars are soft, buttery, and perfectly nostalgic, yet they feel fresh and modern with their delicate pink hue and creamy vanilla frosting. At first bite, the cookie base melts gently, while the frosting adds just the right sweetness. Because they’re baked as bars, they’re easier than cookies, but still feel bakery-worthy.

Moreover, these bars are ideal for gatherings, gifting, or simple weekday baking. While strawberry desserts are often associated with spring celebrations, strawberry-flavored baked treats became popular in American home kitchens during the mid-20th century, especially as sheet-pan desserts gained traction. Over time, they evolved into today’s soft cookie bars, loved for both ease and flavor.

Meanwhile, the balance of vanilla, strawberry, and butter keeps these bars from tasting artificial or overly sweet. As a result, they appeal to kids and adults alike. Whether served chilled or at room temperature, these bars slice beautifully and hold their shape. Ultimately, this recipe delivers comfort, color, and crowd-pleasing flavor in every square.

Recipe Yield: 16 servings

INGREDIENTS

2 cups all-purpose flour
1 cup unsalted butter, softened
1 cup granulated sugar
1 large egg, room temperature
1 Tbsp milk
1 tsp vanilla extract
1 tsp strawberry extract
1/2 tsp baking powder
1/2 tsp salt
2 drops red or pink gel food coloring

Frosting:
1/2 cup unsalted butter, softened
2 cups powdered sugar
1 Tbsp heavy cream
1/2 tsp vanilla extract
Pinch salt

Topping:
2 Tbsp red and white nonpareil sprinkles

INSTRUCTIONS

1. Preheat and prepare:
First, preheat oven to 350°F. Then, line an 8×8-inch baking pan with parchment paper, leaving overhang for easy removal.

2. Mix the wet ingredients:
Next, beat the softened butter and sugar together for 2–3 minutes, until pale, light, and fluffy. Then add the egg, milk, vanilla extract, strawberry extract, and food coloring, mixing until smooth and evenly colored.

3. Add the dry ingredients:
Meanwhile, whisk flour, baking powder, and salt. Gradually add to the wet mixture, mixing just until combined and soft.

4. Bake the cookie base:
Now, spread dough evenly into prepared pan. Bake for 18–22 minutes, until edges are set and the center is just baked through. Cool completely.

5. Make the frosting:
Once cooled, beat butter until creamy. Gradually add powdered sugar, cream, vanilla, and salt until smooth and spreadable.

6. Frost and finish:
Finally, spread frosting evenly over bars and sprinkle generously. Chill 20 minutes before slicing.

Helpful Tips to Perfect This Recipe

• Control the texture: Because overbaking dries cookie bars quickly, remove them as soon as the center is set for a soft, bakery-style bite.
• Enhance strawberry flavor: If desired, add 1 Tbsp freeze-dried strawberry powder to the dough for deeper natural flavor without extra moisture.
• Clean slices every time: For neat squares, wipe the knife between cuts, especially after chilling the frosting.
