Gluten-Free Flourless Peanut Butter Cookies

Ingredients

• 1 cup dark brown sugar
• 1 teaspoon baking soda
• 1 cup smooth or creamy peanut butter
• 1 large egg
• 1 teaspoon vanilla extract

Directions

1. Heat the oven to 350 degrees F. Line 2 rimmed baking sheets with parchment paper. In a small bowl, use your fingers to work the dark brown sugar and baking soda together. Add the peanut butter, egg, and vanilla extract, then mix with a wooden spoon until the batter is smooth and thick.
2. Scoop rounded tablespoons of dough onto the prepared baking sheet. These cookies spread as they bake, so leave about 2 inches between them. Gently press the top of each cookie with the tines of a fork, making a crosshatch pattern.
3. Bake until the cookies rise and then settle back down, about 10 minutes. They should look lightly golden brown.
4. Leave the cookies on the pan to cool for 10 minutes. Then move them to a wire rack and cool completely. Continue the same way with the remaining dough. Store the cookies in an airtight container on the counter for up to 4 days.
