Peanut Butter Chocolate Chip Shortbread Cookies

These delicious shortbread cookies fall apart and melt in your mouth.

Yield: about 15 to 16 cookies

Ingredients

• 1/2 cup unsalted butter (room temperature)
• 1/3 cup creamy peanut butter
• 1/2 teaspoon vanilla extract
• 1 1/4 cups all-purpose flour
• 1/4 cup (31 grams) confectioners' sugar
• Scant 1/2 teapoon kosher or sea salt
• 3/4 cup chocolate chips (semisweet or milk chocolate)

Instructions

1. Cream the butter and the peanut butter together with a mixer. Make sure to get the butter and peanut butter completely combined and creamy.
2. Beat in the vanilla extract.
3. Whisk the dry ingredients together and add to the butter mixture. Mix until the dough comes together and is no longer crumbly.
4. Stir in the chips, and turn the dough out onto a piece of wax paper. Gently pull the dough together and form it into a log. If it is still crumbly, work it with your hands until it holds together smoothly. Roll it up in the wax paper, smoothing the shape as you go. Twist the ends securely. The log will be roughly 7 1/2 to 8 inches long.
5. Refrigerate for at least two hours.
6. While the dough is chilling, heat the oven to 350 degrees F. Line a cookie sheet with parchment or Silpat.
7. Slice the log into 1/2 inch thick slices with a sharp knife. If a slice crumbles a bit, just work the dough back together.
8. Bake on the prepared cookie sheet for about 12 to 14 minutes, depending on how thick your cookies are. The cookies will not be browned, and they may look undone, but don't over-bake.
9. Let the cookies cool on the cookie sheet for 5 minutes before transferring to a rack.
