Equipment

Cookie Sheet

Ingredients

2 tablespoons unsalted butter (28 grams) melted
2 tablespoons peanut butter
1/4 cup light brown sugar (50 grams) or 2 tablespoons white sugar and 2 tablespoons brown sugar
1 large egg yolk discard the white
1/4 teaspoon vanilla
6 tablespoons all-purpose flour (47 grams) level off the top
1/8 teaspoon baking soda
4 tablespoons chocolate chips or Reese's Pieces or a combination

Instructions

Preheat the oven to 350F degrees and line a cookie sheet with parchment paper or a silicone baking mat.
Whisk together the melted butter, peanut butter and sugar until smooth.
Whisk in the egg yolk and vanilla extract. Be sure that you only add the egg yolk and not the entire egg.
Stir in the flour and baking soda until there are no lumps. When measuring the flour, make sure the tablespoon isn't heaping.
Stir in 3 tablespoons of chocolate chips/Reese's. You'll have 1 tablespoon left.
Form the cookie into a ball about 3 inches in diameter. Bake in the preheated oven for about 12-14 minutes or until the top of the cookie is set.
Remove the tray from the oven and dot the remaining 1 tablespoon of chocolate chips or Reese's on top of the cookie.

Notes

Peanut Butter: I highly recommend using smooth, commercial-style peanut butter for the best results. Natural and homemade peanut butter can separate, and lead to poor results.
For 2 Cookies: Divide the dough in half and bake for 10-12 minutes, or until the tops look just set.
