This small batch peanut butter cookies recipe makes delicious cookies full of peanut butter flavor.

Cream butter and sugar. Add in peanut butter, egg yolk and vanilla.

Add in flour, baking soda, baking powder and salt.

Mix into a soft and sticky dough. Cover the bowl and chill the dough for at least an hour.

Roll the dough into 9 balls, and roll each cookie ball into some granulated sugar until it's coated.

Place the balls on the cookie sheet, spaced around 2 inches apart. Press the cookies with a fork.

Bake the cookies for around 10 minutes until the edges are golden brown.

Allow them to cool on the baking tray for 5 minutes before transferring to a wire rack to cool further.
