Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

In a large mixing bowl, combine the creamy peanut butter, granulated sugar, and large egg. Blend until smooth and creamy.

Scoop out approximately 1 tablespoon of the peanut butter mixture and roll it into a ball.

Place the cookie dough balls onto the lined baking sheets, leaving about 2 inches of space between each.

Bake for about 10 minutes until edges are set and the center remains soft.

Immediately press a Hershey's kiss into the center of each cookie after baking.

Let cool on the baking sheet before transferring to a wire rack.
