This no-bake sourdough discard chocolate oatmeal cookies recipe is an easy cookie you can make in under 30 minutes.
It’s a quick stovetop cookie recipe made with cocoa, oats, peanut butter, and tangy sourdough discard or starter.
If you enjoy making cookies, here are a few more that are just as easy to make. Here are a few of our favorites: sourdough gingerbread cookies, a simple butterscotch cookie recipe, sourdough einkorn oatmeal raisin cookies, and classic spritz cookies. These recipes follow the same straightforward approach. They’re the kind of cookies you can make quickly without much fuss.

Ingredients
Variations & Add-Ins
- Quick oats: Swap part or all of the rolled oats for quick oats for a softer texture.
- Crunchy peanut butter: Use crunchy peanut butter to add a little texture throughout the cookies.
- Almond butter: Replace the peanut butter for a slightly different flavor and a smoother finish.
- Cashew butter: Creates a milder, creamy cookie with less peanut flavor.
- Chocolate chips: Stir in a small amount at the end for extra chocolate throughout.
- Peppermint mocha twist: Add a small amount of peppermint extract or crushed peppermint pieces for a cool, chocolate-forward variation.
- Reduced sugar: Slightly cutting back the sugar will give a softer set and less sweetness.
Recipe Tips
Measure everything and be ready: This is a very fast-moving recipe, so have the peanut butter, sourdough discard, oats, and vanilla measured and set aside before turning on the stove.
Be ready once it comes off the heat: After boiling, the mixture thickens quickly, so you’ll want to add and stir everything right away without stopping.
Start timing at a full rolling boil: Don’t count simmering bubbles around the edges; wait until the entire surface is bubbling steadily.
Stir constantly while heating: Continuous stirring helps the sugar dissolve and keeps the cocoa from sticking to the bottom of the pan.
Choose your oats carefully: Quick oats or a mix of quick and rolled oats help the cookies hold together better. We prefer rolled oats for a harder cookie, and my mom prefers quick oats for a softer cookie texture.
Watch humidity and setting time: On humid days, the cookies may take longer to firm up at room temperature.
Line your pan ahead of time: Parchment or wax paper makes scooping and cleanup much easier.
Chill if needed: If the cookies are slightly soft, a short rest in the fridge can help them finish setting.
How To Make No-Bake Sourdough Oatmeal Chocolate Cookies
- Prepare your ingredients: Measure all ingredients and set them near the stove so everything is ready once cooking begins.
- Combine the base ingredients: Add the sugar, milk, cocoa powder, and salt to a saucepan and stir over medium heat until smooth.
- Bring to a full boil: Let the mixture reach a rolling boil and cook for one full minute while stirring constantly.
- Remove from heat and mix in: Take the pan off the heat and stir in the butter, peanut butter, and sourdough discard until fully blended.
- Add flavor and texture: Mix in the vanilla extract, then fold in the oats until evenly coated.
- Scoop the cookies: Drop spoonfuls onto a parchment-lined surface, keeping them evenly sized.
- Let them set: Allow the cookies to rest at room temperature until firm.
Freezing & Storage
- Room temperature storage: Store the cookies in an airtight container at room temperature once fully set.
- Refrigerator storage: Keeping them chilled helps them stay firm, especially in warmer kitchens.
- Freezer storage: Place the cookies in a freezer-safe container or freezer bag and freeze for longer storage.
- Flash freezing: Let the cookies firm up on a lined tray before transferring them to a container so they don’t stick together.
- Thawing: Let frozen cookies sit at room temperature for a short time before serving.
- Make-ahead friendly: These cookies hold their texture well, making them easy to prepare in advance.
How To Gift
- Simple cookie boxes: Place the cookies in a small bakery box lined with parchment paper for an easy, classic presentation.
- Stacked parchment bundles: Stack a few cookies together and wrap them in parchment paper tied with kitchen twine.
- Holiday tins: Arrange the cookies in a tin with parchment between layers to keep them from sticking.
- Freezer-ready gifts: Wrap and freeze the cookies ahead of time, then thaw before gifting.
- Casual sharing: Pack a few cookies in a reusable container for easy sharing with friends or neighbors.
