Ingredients
  

For the Cookie Dough
  • 1 box 15.25 ounces strawberry cake mix Choose a quality box for best flavor.
  • 2 large eggs Use at room temperature for best results.
  • 1/2 cup vegetable oil Neutral oils work best to not mask strawberry flavor.
  • 1/4 cup all-purpose flour
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1 teaspoon vanilla extract
For the Buttercream Filling
  • 1 cup unsalted butter, softened Use European-style butter for richer flavor.
  • 4 cups powdered sugar
  • 2–4 tablespoons heavy cream or milk Adjust for consistency.
  • 1 teaspoon vanilla extract
  • 1/4 cup strawberry jam or puree Enhances strawberry flavor.

Method
 

Make the Dough and Bake the Cookies
  1. Preheat your oven to 375°F (190°C) and line several baking sheets with parchment or silicone mats.
  2. In a large mixing bowl, combine the strawberry cake mix, eggs, vegetable oil, all-purpose flour, baking powder, and salt.
  3. Mix on medium speed with an electric mixer until just combined; the dough should be thick and slightly sticky.
  4. Use a small cookie scoop (about 1.5 tablespoons) to drop rounded balls onto the prepared sheets, spacing them about 2 inches apart.
  5. Gently flatten each ball slightly to ensure even baking.
  6. Bake for 8–10 minutes, until edges are set and lightly golden while centers remain soft.
  7. Transfer cookies to a wire rack to cool completely before frosting.
Prepare the Strawberry Buttercream
  1. While cookies cool, beat the softened unsalted butter until light and fluffy, about 2–3 minutes.
  2. Gradually add powdered sugar until smooth, starting on low speed.
  3. Beat in cream or milk, vanilla extract, and strawberry jam or puree until pale pink and airy.
Assemble the Sandwich Cookies
  1. Once cookies are completely cool, pair similar-sized cookies.
  2. Spread a generous dollop of buttercream onto the flat side of one cookie and top with another cookie.
  3. Roll the edges in sprinkles or finely chopped freeze-dried strawberries if desired.

Notes

For best results, allow the dough to chill 10-15 minutes if it feels too sticky. Store cookies in an airtight container.
