Method
Prepare the Dough
- In a large mixing bowl, beat the softened butter and granulated sugar together with an electric mixer on medium speed until pale and fluffy, about 3 minutes.
- Mix in the egg and vanilla extract until smooth and combined.
- Gradually add the flour and salt, mixing on low speed just until the dough comes together. Do not overmix.
- Wrap the dough in plastic wrap and chill in the refrigerator for at least 1 hour to prevent spreading.
Shape and Bake
- Preheat the oven to 350°F (175°C). On a lightly floured surface, roll out the chilled dough to about 1/4-inch thickness.
- Use a heart-shaped cookie cutter to cut out cookies. Place them on a parchment-lined baking sheet and chill again for 10 minutes if the dough feels soft.
- Bake for 8-10 minutes, until edges are lightly set but not browned. Cool completely on a wire rack.
Make the Filling
- In a bowl, beat the softened butter until creamy. Gradually add powdered sugar, vanilla, and enough milk to reach a spreadable or pipeable consistency.
- Tint with pink food coloring if desired.
- Pipe or spread about 1-2 tablespoons of buttercream onto the flat side of one cookie. Top with another cookie and gently press together. Repeat with remaining cookies.
Notes
For best results, chill the dough twice to ensure cookies hold their shape. Store assembled sandwiches in an airtight container at room temperature for up to 3 days. Cookies become softer over time as they absorb filling moisture.
