Preparing the Cookies
1. When ready to bake the cookies, preheat your oven to 350 degrees and line two baking sheets with parchment paper.
2. Roll 12 peanut butter dough balls and 12 chocolate dough balls, each about 1 tablespoon.
3. Take the peanut butter ball and flatten it into a disc. Roll the chocolate ball briefly in the sugar that place the chocolate ball on top of the peanut butter disc.
4. Gently press and fold them together to create the marbled effect. Roll the combined dough into a smooth ball and continue with the others.
5. Roll the marbled balls in sugar evenly coating them and arrange them on a baking sheet, spaced 2 inches apart.
6. Bake each batch—one baking sheet at a time—for 10-12 minutes, until the edges begin to set.
7. Let cool on the sheet for 5–7 minutes before transferring to a wire rack to cool completely.
