Butter Swimsuit Cookies

This recipe comes from Simply Texas’ Butter Swimmer Cookies. She mentioned that it came from her grandmother. I can only imagine how long it has been around.

It’s very easy to make using ingredients you may have on hand. The only ingredient you may need is buttermilk, but you can easily make your own homemade buttermilk. These butter cookies are delicious on their own or coated with your favorite jam.

Ingredients in Butter Swimsuit Cookies

As mentioned earlier, the ingredients for these butter cookies are the ones you’re most likely to have in your kitchen.

Flour : I used all-purpose flour. We have not tested flour substitutes, so I can’t speak to their effectiveness.

Sugar : Just a tablespoon of granulated sugar gives the cookies a hint of sweetness and helps to crisp up the top.

Buttermilk : If you don’t have it on hand, you can make your own butter milk. I don’t recommend using milk in the recipe; you won’t get the tartness you get from buttermilk.

How to store the cookies

Cookies are best eaten fresh, usually on the day they are baked. If you want to make them a day ahead.

  • Bake the cookies.
  • Allow cookies to cool to room temperature.
  • Wrap tightly in aluminum foil (use plastic wrap only if cookies are completely cool; trapped hot air may cause cookies to mold).
  • Place in the refrigerator until ready to use. (You can also leave them at room temperature if you wish).
  • When ready to serve, heat in the oven on the lowest temperature for 10 minutes.

How to freeze cookies

Wrap cooled cookies tightly in aluminum foil or plastic wrap and place in freezer-safe storage bags. If they are wrapped tightly enough that air can’t get in, they should stay fresh for several months.

  • 2½ cups (312.5 g) all-purpose flour
  • 4 teaspoons baking powder
  • 1 tablespoon granulated sugar
  • 2 teaspoons kosher salt
  • 2 cups (490 g) buttermilk
  • ½ cup (1 stick, 113 g) butter, melted


  • Preheat the oven to 450°F.
  • Add flour, baking powder, sugar, and salt to a medium bowl. Use a whisk to sift ingredients.
  • Pour in the buttermilk and stir until mostly combined, being careful not to overwork the batter.
  • Pour the melted butter into an 8×8-inch baking dish*. Place the dough on top of the butter and use a spatula (or your hands) to evenly spread the dough out to the edges of the pan.
  • Cut the unbaked dough into 9 squares (3×3 pattern). Bake for 28 minutes, or until the tops are golden brown.
  • Allow the butter to be absorbed into the biscuits before cutting and serving.


You can place the baking dish on a baking sheet in case of spillover.
