Step 1

Preheat the oven to 350F and line 2 baking sheets with parchment paper or silicone baking mats.

Step 2

In a large bowl, whisk together the starter, peanut butter, butter, brown sugar, eggs and vanilla until combined.

Step 3

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.

Step 4

Add the dry ingredients to the starter mixture and combine. The dough will be soft but shouldn’t be sticky, and should be able to hold its shape. If you need to add more flour to get the right consistency, add ¼ cup at a time until you can form it into a ball.

Step 5

Use a cookie scoop to roll the dough into balls and then roll them in sugar.

Step 6

Place the cookie balls on the prepared cookie sheet.

Step 7

Use a fork to press down and create criss-cross lines on the cookie – first in one direction, and then in a second direction

Step 8

Bake for 10-12 minutes, until golden brown but still soft.

Step 9

Allow the cookies to rest on the hot cookie sheet for 1-2 minutes.

Step 10

Remove to a wire rack and cool.

Step 11

Enjoy!
