Ingredients You’ll Need

1 box (15.25 oz) strawberry cake mix (like Duncan Hines Strawberry Supreme)
1/2 cup vegetable oil
2 large eggs
Sanding sugar (for rolling)

For the Buttercream Filling:

1/2 cup unsalted butter, softened
1 1/2 cups powdered sugar
1–2 tablespoons milk or cream (as needed)
1/2 teaspoon vanilla extract (or strawberry extract for more berry flavor)

Optional: Add a drop of pink or red food coloring to the buttercream for extra color.

Step-by-Step Instructions

Preheat oven to 350°F (175°C). In a stand mixer, combine cake mix, oil, and eggs. Mix until a soft dough forms.

2. Shape and Roll

Scoop dough into 1-tablespoon balls (a cookie scoop is helpful). Roll each ball in sanding sugar and place on a parchment-lined baking sheet.

3. Bake the Cookies

Bake for 8–10 minutes, just until the edges are set. Do not overbake. Let cool on the pan for 5 minutes before transferring to a wire rack.

4. Make the Buttercream

While cookies cool, beat butter until creamy. Add powdered sugar, milk/cream, and vanilla. Beat until fluffy and smooth. Adjust consistency as needed.

5. Assemble Sandwich Cookies

Pair up cookies by size. Pipe or spread buttercream onto the flat side of one cookie, then sandwich with another.

Serving and Storage Tips

Serve cookies at room temperature with a glass of milk or a cup of tea. They’re great for dessert trays and gifting.

Store in an airtight container at room temp for up to 3 days or refrigerate for up to a week. Freeze assembled cookies (without buttercream if preferred) for up to 2 months.

Helpful Notes

Don’t Overbake: Keep them soft by pulling them out just as the edges set.
Flavor Boost: Add strawberry extract or zest to the dough for extra punch.
Make Mini Sandwiches: Use a teaspoon scoop for bite-size cookies.
Add Sprinkles: Roll in nonpareils or colored sugar for festive fun.
