03 - 2/3 cup granulated sugar
04 - 1 large egg
05 - 2 tablespoons milk

# How to Make It:

01 - Preheat oven to 350°F and line two baking sheets with parchment paper.
02 - In a bowl, whisk together flour, baking powder, and salt.
03 - In a large mixing bowl, cream butter and sugar until light and fluffy, approximately 2-3 minutes.
04 - Beat in egg, milk, and vanilla extract until fully combined.
05 - Gradually add dry ingredients to wet mixture, mixing until a soft dough forms.
06 - Roll dough into 1-inch balls and place them 2 inches apart on prepared baking sheets.
07 - Gently flatten each ball with your palm or the bottom of a glass to approximately 1/4-inch thickness.
08 - Bake for 10-12 minutes until edges are just golden. Remove from oven and allow to cool completely on baking sheets.

10 - Spread or pipe approximately 1 tablespoon of cream filling onto the flat side of half the cookies. Top with remaining cookies to form sandwiches.

# Expert Tips:

01 -
  • They bake in minutes and come out looking like tiny edible treasures you didn't know you could make.
  • The cream filling is so silky that people always ask what bakery you got them from, then act shocked when you say your kitchen.
  • Perfect for sharing at parties or just keeping a batch hidden for yourself on a quiet afternoon.
02 -
  • The cookies must be completely cool before you add the filling, or the heat will melt it and cause everything to slide around—I learned this the messy way.
  • Don't skip sifting the powdered sugar for the filling; those tiny lumps ruin the silky texture that makes people think these came from a professional bakery.
03 -
  • If your kitchen is warm, chill the cream filling for 15 minutes before piping—it'll be easier to work with and hold its shape better.
  • Use an offset spatula or small butter knife to spread the filling if you don't have a piping bag; it gives you more control and looks just as professional.
