Ingredients

For the Strawberry Cake Mix Cookies:

  • 1 (15.25 oz) box strawberry cake mix (such as Duncan Hines)
  • 2 large eggs
  • 1/3 cup vegetable oil
  • 1 1/2 cups sanding sugar (for rolling)

For the Small Batch Almond Buttercream:

  • 1 cup (2 sticks) unsalted butter, softened
  • 1 pinch salt
  • 2 teaspoons vanilla extract
  • 1/2 teaspoon almond extract
  • 1/8 cup heavy cream (plus more as needed)
  • 6 cups powdered sugar

Directions

Step 1: Make the Cookies

  1. Preheat your oven to 350°F (175°C) and line a large cookie sheet with parchment paper.
  2. In a stand mixer fitted with a paddle attachment, combine the strawberry cake mix, eggs, and vegetable oil. Mix on low speed until all ingredients are just combined and a soft dough forms.
  3. Spread the sanding sugar onto a plate. Scoop the cookie dough using a 1-inch cookie scoop, then roll each scoop of dough into a ball with your hands.
  4. Roll the dough balls in the sanding sugar until well coated.
  5. Place the coated dough balls on the prepared cookie sheet, spacing them about 3 inches apart.
  6. Bake for 7-9 minutes, or until the cookies are set and the edges are lightly golden.
  7. Remove from the oven and transfer the cookies to a wire rack to cool completely.

Step 2: Prepare the Almond Buttercream

  1. In a clean stand mixer, whip the softened butter on medium speed until light and fluffy, about 3 minutes.
  2. Add a pinch of salt, vanilla extract, almond extract, and heavy cream, and continue to whip until well combined.
  3. Gradually add the powdered sugar, about one cup at a time, beating on low speed to prevent a sugar cloud. Once incorporated, increase the speed to medium-high and whip until the buttercream is smooth and fluffy.
  4. If the buttercream is too thick, add a bit more heavy cream, one teaspoon at a time, until you reach your desired consistency.

Step 3: Assemble the Sandwich Cookies

  1. Transfer the almond buttercream to a piping bag fitted with a round tip, or simply snip the end of the bag if you prefer to pipe without a tip.
  2. Flip one of the cookies over so the flat side is facing up. Pipe a swirl of buttercream on the flat side, extending the frosting to the edges.
  3. Top with another cookie, pressing down gently to create a sandwich. Repeat with the remaining cookies and buttercream.
  4. Store the finished sandwich cookies in an airtight container in the refrigerator for up to one week.

Serving and Storage Tips

  • Serving: These cookies are best enjoyed slightly chilled, as it allows the buttercream to hold its shape and provides a refreshing contrast to the soft cookie.
  • Storage: Keep the assembled sandwich cookies in an airtight container in the refrigerator for up to a week. If you prefer a softer texture, let them sit at room temperature for a few minutes before serving.

Helpful Notes

  • Room Temperature Ingredients: For the buttercream, it’s best to use room temperature butter to achieve a smooth and creamy consistency.
  • Consistency: If your buttercream is too thick, add a bit more heavy cream. If it’s too thin, add a bit more powdered sugar until it reaches the desired thickness.
  • Decorating Options: You can add a pop of color by using colored sanding sugar, or dust the edges of the buttercream with sprinkles for a fun twist.

Tips from Well-Known Chefs

  • Rosanna Pansino: “For a burst of extra flavor, add a teaspoon of strawberry extract to the cookie dough to intensify the strawberry taste!”
  • Mary Berry: “For a perfectly even cookie, use a cookie scoop to measure out your dough. This ensures consistent baking and presentation.”
  • Christina Tosi: “To achieve an ultra-smooth buttercream, whip the butter first until it’s very light and fluffy before adding other ingredients.”
