My Favorite Cookie with a Tangy Twist

The Origin of My Sourdough Discard Monster Cookies

If you’ve wandered into my kitchen in West Lafayette lately, there’s a good chance you caught the scent of something sweet and slightly tangy. These sourdough discard monster cookies are what I bake when I need joy in edible form chewy, colorful, and crammed with peanut butter, oats, chocolate chips, and candy-coated crunch.

It started on a rainy Saturday. My kids wanted cookies, and I had a jar of sourdough discard begging for purpose. I didn’t want to waste it but I also didn’t feel like baking bread. So I played around with my go-to monster cookie recipe, folded in the discard, and held my breath.

What came out of the oven were hands-down the best monster cookies we’ve ever made. Chewy in the center, crisp at the edges, and a whisper of tang that gave them a depth store-bought versions never have.

Now they’re on regular rotation, especially when I’m running low on time but high on discard. The recipe is forgiving you can use discard straight from the fridge, no feeding necessary.

Why Sourdough Discard Elevates Classic Monster Cookies

Even if you’re new to baking with discard, this recipe is a great starting point. No feeding, no rising just stir, scoop, and bake. If you’re ever staring at a jar of leftover starter and wondering what to do, trust me: sourdough discard monster cookies are the answer.

Ingredients That Make the Magic

Pantry Staples Meet Sourdough Gold

What I love about these sourdough discard monster cookies is how they transform simple pantry staples into something special. Most of what you need is probably already in your kitchen, and the sourdough discard makes it shine.

Here’s what goes into each batch:

• Butter & Peanut Butter: Melted butter keeps things chewy and rich. Peanut butter adds that nutty backbone we expect in a monster cookie.
• Brown Sugar & Granulated Sugar: A mix of sugars gives you crisp edges and a deep molasses chew.
• Egg & Vanilla: Just one egg, for structure and softness, and a splash of vanilla to round things out.
• Sourdough Discard: The star of the show. You’ll need ¾ cup of unfed starter (100% hydration). No feeding, no fuss.
• All-Purpose Flour & Rolled Oats: Flour holds it together. Oats bring texture and that classic monster cookie bite.
• Baking Soda & Salt: For lift and balance.
• Chocolate Chips & M&Ms: I like semisweet chips and classic colorful M&Ms, but you can swap as your heart desires.

This mix creates a soft, thick cookie with a golden edge and gooey center. The sourdough adds moisture and that magic tang that keeps people reaching for “just one more.”

Customizing Your Cookies Like a Pro

One of the best parts about monster cookies is how flexible they are. Want to switch things up? Here are a few delicious variations:

• Swap the candy: Use chopped peanut butter cups, butterscotch chips, or even crushed pretzels.
• Go gluten-free: Sub in a 1:1 GF baking blend and certified GF oats.
• Nut-free? Use sunflower seed butter or Wowbutter and skip the M&Ms if needed.

Baking Technique for Thick, Chewy Perfection

Mixing Tips for the Best Texture

Perfect sourdough discard monster cookies start with the right mixing technique. It’s not complicated but there’s an art to it.

Start by whisking the melted butter, peanut butter, and sugars until smooth and creamy. This step helps dissolve the sugar and set up that chewy texture we’re after. Beat in the egg and vanilla, then stir in your sourdough discard. You’ll notice the mixture turns glossy and thick that’s a good sign.

In a separate bowl, whisk together your dry ingredients: flour, oats, baking soda, and salt. Once mixed, add this to the wet ingredients and stir just until combined. Don’t overmix. Overworking the dough develops too much gluten, which leads to tough cookies. Fold in your chocolate chips and M&Ms last, reserving a few for pressing on top right before baking. It makes them look extra bakery-style.

The dough will be slightly sticky. You can chill it for 20 minutes if you want taller cookies, but it’s not necessary. I often bake them right away for a slightly flatter but still soft center.

These mixing steps are simple, but they’re the foundation for success. And if you want more fun discard-friendly treats, try these sourdough discard cinnamon roll bites they’re a hit with kids and adults alike.

Baking Time, Temperature, and Storage

Bake at 350°F (175°C) for 10–12 minutes. You want golden edges and slightly soft centers. The cookies continue to cook on the sheet after you pull them from the oven, so don’t wait for them to look fully set.

Let them cool for 5 minutes on the baking sheet, then transfer to a wire rack. Stored in an airtight container, they’ll stay chewy for up to 5 days. You can also freeze the dough balls just bake from frozen, adding 2 minutes.
