Ingredients
- 1/2 cup butter, softened
- 1 cup sugar
- 1 large egg, room temperature
- 1 teaspoon vanilla extract
- 2-1/2 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup buttermilk
- Frosting:
- 3 tablespoons butter, softened
- 3-1/2 cups confectioners’ sugar
- 1/4 cup 2% milk
- 1 teaspoon vanilla extract
- 1/2 cup finely chopped walnuts (optional)
Instructions
- Step 1: Preheat your oven to 375°F (190°C). In a large bowl, cream together the softened butter and sugar until the mixture is light and fluffy.
- Step 2: Beat in the egg and vanilla extract until well combined.
- Step 3: In a separate bowl, whisk together the flour, baking soda, and salt.
- Step 4: Gradually add the dry ingredients to the creamed mixture, alternating with the buttermilk. Begin and end with the flour mixture. Beat well after each addition to ensure a smooth dough.
- Step 5: Drop rounded tablespoonfuls of dough about 2 inches apart onto greased baking sheets.
- Step 6: Bake for 10 to 12 minutes, or until the edges are lightly browned. Remove cookies from the oven and transfer them to wire racks to cool completely.
- Step 7: To make the frosting, combine the softened butter, confectioners’ sugar, milk, and vanilla extract in a bowl. Beat until smooth and creamy.
- Step 8: Spread the frosting over the cooled cookies. If desired, sprinkle with finely chopped walnuts for added texture and flavor.
Tips & Variations
- Use room temperature ingredients to help the dough come together smoothly.
- For a nut-free version, simply omit the walnuts or substitute with toasted coconut flakes.
- Chill the dough for 30 minutes before baking if you prefer thicker cookies.
- Try adding a pinch of cinnamon or nutmeg to the dry ingredients for a warm spice twist.
Storage
Store the frosted cookies in an airtight container at room temperature for up to 3 days. For longer storage, keep them refrigerated and bring to room temperature before serving. Cookies can also be frozen unfrosted for up to 2 months; frost them after thawing.

Ingredients
Cookie Dough
- 1/2 cup butter, softened
- 1 cup sugar
- 1 large egg, room temperature
- 1 teaspoon vanilla extract
- 2–1/2 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup buttermilk
Frosting
- 3 tablespoons butter, softened
- 3–1/2 cups confectioners’ sugar
- 1/4 cup 2% milk
- 1 teaspoon vanilla extract
- 1/2 cup finely chopped walnuts (optional)
Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for baking the cookies.
- Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and sugar until the mixture is light and fluffy, which helps create a tender texture.
- Add Egg and Vanilla: Beat in the egg and vanilla extract to the creamed butter and sugar until fully combined and smooth.
- Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt to evenly distribute the leavening and seasoning.
- Mix Dough: Alternately add the dry ingredient mixture and buttermilk to the creamed mixture, beginning and ending with the dry ingredients. Beat well after each addition until smooth and creamy.
- Shape Cookies: Drop dough by rounded tablespoonfuls about 2 inches apart onto greased baking sheets to allow space for spreading during baking.
- Bake: Bake in the preheated oven for 10 to 12 minutes until the edges are lightly browned, indicating they are cooked through but still soft.
- Cool Cookies: Remove the baking sheets from the oven, and transfer the cookies to wire racks to cool completely before frosting to prevent melting.

- Frost Cookies: Spread the prepared frosting over the cooled cookies evenly. If desired, sprinkle the tops with finely chopped walnuts to add a crunchy texture.
