Sourdough discard dessert recipes are very popular as sourdough adds an intensity of flavor and a touch of tanginess that benefits sweet recipes.

Why put Sourdough Discard in cookies?

Using sourdough starter discard to bake may seem like an unnecessary addition, but it’s actually a very beneficial way to use up your extra sourdough discard. Sourdough discard will help bring more rise and life to your baked goods because of the presence of live yeast that it contain. Many recipes, like pancake, will be fluffier and fuller.

A sourdough discard also brings a scrumptious depth of flavor and slight tanginess that balances out sweet baked goods.

Should the starter be fed or unfed for discard cookies?

When baking with sourdough discard, the recipe you are using will determine if you need the starter to be fed or unfed. Some recipes require a more active discard that isn’t lively enough to bake bread with, but freshly fed and lively enough to give the recipe some structure.

These cookies have the advantage of using starter fed or unfed, so you can choose when you want to use the starter discard. The final result may lead to a stronger flavor or a more mild flavor depending where your discard is.

Are Sourdough Cookies better for you?

Sourdough can be digested easier than plain white wheat flour. Sourdough is nutrient rich and can ease digestion and absorption of certain nutrients. The Lactic Acid that is present in sourdough helps aid in the breakdown of bacteria. Here is a great article on health pros and cons of sourdough.

So while sourdough itself is easier to digest, lower in gluten and contains important probiotics; cookies themselves can hardly be considered healthy. Using a sourdough discard can help lower the amount of white flour needed in a recipe, though it won’t usually replace all of it.

Is Levain the same as Sourdough?

Levain is a subset of sourdough. Levain is a French term meaning leaven or yeast. It refers to the active culture of yeasts used in baking, such as bread dough, sourdough starter, and beers. Yeast cultures are made up of live organisms that start fermenting dough, causing it to rise. A leavened loaf of bread contains yeast cells; they help make bread rise.

What can I do with Discarded Sourdough Starter?

Sourdough discard is the leftover starter that remains after feeding the starter. Discard is inevitable when it comes to sourdough baking. Here are a few of our favorite options to use up sourdough discard rather than discarding it.

  1. Sourdough Waffles
  2. Sourdough Pancakes
  3. Sourdough Banana Bread
  4. Sourdough Cinnamon Rolls
  5. Sourdough Molasses Cookies
  6. Sourdough Pretzels
  7. Sourdough Bagels
  8. Sourdough English Muffins
  9. Sourdough Pie Crust
  10. Sourdough Muffins

Can you Freeze Sourdough Cookie dough?

Sourdough cookie dough can be frozen. Sourdough freezes really well and can be baked from from a frozen state. Freezing sourdough cookie dough can be accomplished in a few simple steps.

  • Portion out dough
  • Roll dough into cookie sized balls
  • Place dough on parchment paper on a cookie sheet
  • Place in freezer and flash freeze for 1-2 hours until frozen solid
  • Remove dough balls from the freezer

Peanut Butter Chocolate Chip Cookies With Sourdough Recipe

You can use sourdough starter in almost any stage, but keep in mind if your starter is very weak it may affect the flavor of these cookies. They will still be scrumptious, just maybe not as vibrant and strong.


  1. Fully active starter will puff the cookies up more. If your using starter that’s been unfed in your fridge several weeks don’t expect much puffing up. But you will certainly have a strong tangy flavor in your cookies. So if you want more flavor use an older unfed starter.
  2. If you want to incorporate chocolate chips, they pair well with a tangy starter.
  3. Creamy peanut butter will give you a smooth, pleasant texture. You can use chunky peanut butter if you prefer, but be sure it’s a peanut butter with some added sweetener. An all natural peanut butter will likely yield bland cookies that will need extra sugar.
  4. Use granulated sugar for the dipping of the dough balls and criss cross pattern to give them that iconic peanut butter cookie look.

Tips for evenly baked cookies:

Cookie dough bakes best when it is evenly sized and placed evenly apart on your baking sheet. I recommend these steps to control the size and separation of your cookies.

  1. Line the baking sheets with parchment paper, or use silicone matts. We really like the ones with the cookie spacing marked on them. Cookies bake evenly and they are snap to use.
  2. Use the correct sized cookie scoop. Please use a cookie dough scoop to ensure uniform amounts of dough for every cookie every time.

What can I add to my Peanut Butter Cookies?

Add your favorite baking chips to give these cookies even more. We love white chocolate chips, traditional chocolate chips, even butterscotch chips. Peanut butter cookies can definitely hold their own, but they are also a great cookie to build on.

Can I freeze Peanut Butter Cookies?

Cookies usually freeze and store very well when properly packaged. They make great treats that can be enjoyed shortly after bringing them out of the freezer and allowing them to thaw for a short while. Here’s how to freeze your Peanut Butter Cookies

  1. Allow you cookies to fully cool and gently place them into a heavy duty freezer ziplock bag.

  3. Label the bag with the recipe name and date.

Peanut Butter Chocolate Chip Cookies are a delicious twist on an old American Favorite cookie. Including sourdough starter adds a deeper flavor with a bit of tang. Bursts of sweet chocolate in these flavorful peanut butter cookies make a good cookie great.


  • 1 cup sourdough starter -240 grams
  • 1 cup peanut butter - 255 grams
  • 1/2 cup organic coconut oil (or butter)-softened - 112 grams
  • 1 cup brown sugar (firmly packed)- 175 grams

  • 1 tsp. baking soda- 6 grams

  • 1 cup (165 grams)to 2 cups (315 grams) flavored baking chips (optional-choose any kind you like)


Preheat Oven to 350 Degrees F.

In a large mixing bowl: Mix together the brown sugar, peanut butter, vanilla and softened coconut oil.

Add in the sourdough starter, and eggs. Mix Gently until combined.

In a smaller mixing bowl Sift together the dry ingredients (except the chips).

Roll the dough into one inch balls.

OPTIONAL: For more sweet roll the cookie balls in sugar now.

Place each ball 2 to three inches apart on your lined baking sheet. They will expand and need room on the sheet.

The stage of your starter Matters:

  • A fully fed and active starter with a mild fruity smell will offer a less intensely flavored cookie that puff more.
  • An unfed or tangy starter will enhance the flavor of these cookies but the cookies will not be as cake like.

The AMOUNT of your starter matters too.

I've made this recipe with only half the starter amount called for and the cookies turned out great. They DO have less puff and a bit more peanut butter flavor if that is what your after.

I have yet to make these (and I make them all the time) and turn out what WE think is a bad cookie.

That's why you see so many notes. Sourdough personalizes this and other recipes. Your starter is different than mine. Do what works for you.

For flatter cookies:

Eliminate the baking powder and baking soda. The starter will still give some leavening.

For puffy cookies that are sweeter:

  1. Use a freshly fed or recently fed starter
  2. Add 1/4 to 1/2 Cup granulated sugar to taste
  3. Use a sweetened peanut butter

The chocolate chips are optional.

They may be omitted or replaced with other baking chips you may prefer. Some good choices are white chocolate chips and peanut butter chips.
