Step 1

Preheat oven to 350 degrees. Line a baking sheet with a baking mat or parchment paper.

Step 2

Using a wooden spoon, mix together the peanut butter, white sugar and egg until smooth.

Step 3

Form dough into heaping tablespoons (about 3/4 inch). Then roll the dough ball in a small bowl of sugar, if desired, to coat the outside. Place on the baking sheet at least 2 inches apart, and then use a fork to flatten and form a cross pattern.

Step 4

Bake for 10-15 minutes, until the cookies are just slightly browned on the bottom. Be careful not to over-bake. Remove and let cool on the baking sheet for 1 minute, then transfer to a wire rack to cool completely.

Step 5

Serve and enjoy!
