Ingredients
Dry Ingredients
- 1 ⅔ cup all purpose flour
- ½ tsp baking powder
- ½ tsp baking soda
- ¼ tsp salt
Wet Ingredients
- ½ cup unsalted butter (softened, room temperature)
- 1 cup granulated sugar (plus ½ cup for rolling)
- 1 egg
- 2 tsp vanilla extract
- 2 tbsp espresso powder
- 1 tbsp condensed milk
Instructions
- Preheat Oven: Preheat your oven to 350 degrees F (177 degrees C) and prepare two baking sheets by lining them with parchment paper to prevent sticking.
- Combine Dry Ingredients: In a small bowl, whisk together 1 ⅔ cups of all purpose flour, ½ tsp baking powder, ½ tsp baking soda, and ¼ tsp salt. Set aside.
- Cream Butter and Sugar: In a separate bowl or the bowl of a stand mixer, cream ½ cup softened unsalted butter with 1 cup granulated sugar until light and fluffy.
- Add Egg and Vanilla: Mix in 1 egg and 2 tsp vanilla extract until fully combined.
- Combine Dry and Wet Mixtures: Gradually add the dry ingredients to the wet mixture, mixing just until combined to form the base cookie dough.
- Divide Dough and Flavor: Scoop two-thirds of the dough into a separate bowl and mix in 2 tbsp espresso powder until fully incorporated and dough turns brown. To the remaining one-third dough, add 1 tbsp condensed milk and mix until combined.
- Create Marble Dough Balls: Take 2 tbsp of espresso dough and 1 tbsp of condensed milk dough, combine gently into a single dough ball weighing approximately 50 grams.
- Coat in Sugar: Roll each dough ball in ½ cup granulated sugar until coated, then place onto the prepared baking sheets.
- Bake Cookies: Bake in the preheated oven for 12-14 minutes, or until the edges are lightly golden brown.
- Cool and Serve: Remove from oven and allow cookies to cool on baking sheets for a few minutes before transferring to a wire rack to cool completely.
Notes
- Use instant espresso powder for best coffee flavor; adjust espresso powder quantity for a stronger or milder coffee taste.
- Ensure butter is softened but not melted for optimal texture.
- Cookie dough balls should weigh about 50 grams each to ensure even baking.
- Rolling dough balls in sugar adds a sweet crunch and a slight crackle on the cookie surface.
- Storage: Keep cookies in an airtight container at room temperature for up to 5 days.
