🧁Ingredients

For the cookies:

1/2 tsp baking soda
1/4 tsp salt
3/4 cup unsalted butter (softened)
3/4 cup granulated sugar
1/2 cup packed brown sugar
1 large egg
1 tsp vanilla extract

Optional: Add-ins like mini chocolate chips, sprinkles, or a touch of almond extract

For the buttercream filling:

1/2 cup unsalted butter (softened)
1 1/2 cups powdered sugar
1–2 tbsp heavy cream or milk
1 tsp vanilla extract
Food coloring (optional)
Sprinkles for rolling the edges (optional but fun!) 🎉

👩‍🍳 Step By Step Instructions

1. Make the Cookies

Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
In a bowl, mix flour, baking soda, and salt. Set aside.
In another bowl, beat butter and both sugars until creamy.
Add egg and vanilla, and mix until smooth.
Gradually add the dry ingredients until a soft dough forms.
Scoop 1-inch balls and place on the baking sheet.
Flatten slightly with your hand or the bottom of a glass.
Bake for 9–11 minutes until the edges are just golden. Let cool completely.

2. Make the Buttercream Filling

Beat the softened butter until smooth and fluffy.
Add powdered sugar a little at a time.
Add cream and vanilla, and beat until the frosting is light and fluffy (about 2–3 minutes).
If using food coloring, mix it in now for fun pastel or bold hues! 💗💙💛

3. Assemble the Cookie Sandwiches

Flip half the cookies over.
Pipe or spread a generous layer of buttercream onto the flat side.
Top with another cookie and gently press together.
Optional: Roll the edges in sprinkles or crushed candy for extra flair!

🌟 Tips & Tricks

Chill assembled sandwiches for 10–15 minutes to help them set before serving
