Instructions

  1. In a large bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt. Set to the side. 
    210 grams all-purpose flour, 5 grams baking soda, 2 grams baking powder, 3 grams salt
  2. To the bowl of a stand mixer with the paddle attachment, cream the room-temperature butter, brown sugar, and white sugar at medium speed, about 2-3 minutes or until light and fluffy.
    This can also be done with a hand mixer.

  4. Gradually add the dry ingredients while mixing on low speed. Stop to scrape the sides of the bowl when necessary. 
  5. Wrap the cookie dough in plastic wrap and chill in the fridge for at least 4 hours or overnight. 
  6. Once ready, preheat the oven to 350 degrees F and line a rimmed baking sheet with parchment paper. With a cookie scoop or hands, roll a heaping Tablespoon of peanut butter cookie dough into a round ball. Roll each dough ball in the bowl of granulated sugar and place on the prepared baking sheet about 2 inches apart. I bake 12 at a time.

Variations

If you're looking to add an even greater twist to this classic cookie recipe, instead of topping them with Caramel Kisses, Hugs, or mini Peanut Butter Cups!
For a little bit of extra festive color, roll each dough ball in colored sugar like red and green instead of white!

How to Store

Once the cookies have cooled to room temperature and the Kisses have set, store the cookies in an airtight container for 5-7 days. 

FAQs:

Can I make Sourdough Peanut Butter Blossoms with other nut butter, like almond butter?

For the best results, I recommend using processed peanut butter, like Jiff or Skippy, rather than natural peanut butter. However, you still can opt for other peanut butter options, especially sunflower seed butter for a nut-free option.

How do I keep Sourdough Peanut Butter Blossoms from spreading while baking?

The cookie dough must be chilled for at least 4 hours in the fridge before baking. This is a soft dough, and if it is not chilled properly, the dough will spread while being baked. 

Can I freeze the cookie dough?

Yes! For ease, I suggest rolling the cookie dough into balls and storing them in a freezer-safe bag for up to a few months. Before baking, thaw back to room temperature and bake.
