Why You’ll Love This Recipe
I love how effortlessly this recipe delivers on flavor and texture. I combine pantry staples, boil them briefly, scoop them out, and let them set while I relax. The result is a soft, fudgy cookie packed with peanut butter and chocolate goodness—it’s a family favorite every time.
Ingredients
(Here's a tip: Check out the full list of ingredients and measurements in the recipe card below.)
- granulated sugar
- salted butter
- milk
- unsweetened cocoa powder
- creamy peanut butter
- pure vanilla extract
- quick-cook oats
Directions
- I line two baking sheets with parchment or wax paper.
- In a saucepan, I bring sugar, butter, milk, and cocoa to a rolling boil over medium heat. Once the center bubbles too, I boil it for exactly 60 seconds—timing is key.
- I remove it from heat, stir in peanut butter, vanilla, and oats until fully combined.
- I drop spoonfuls onto the prepared sheets and let them set at room temperature, about 30 minutes.
Servings and timing
- Servings: around 24 cookies
- Prep time: ~10 minutes
- Cook time: ~5 minutes
- Setting time: ~30 minutes
- Total time: around 45 minutes
Variations
- Use rolled oats for a chewier texture.
- For a nut-free version, I swap in sunflower seed butter.
- To make it dairy-free, I use vegan butter and plant-based milk.
- When I want extra fudgy cookies, I add a pinch of salt or let them sit longer to firm up more.
Storage/Reheating
- I store them at room temperature in an airtight container for up to one week.
- For longer storage, I freeze the cookies (layered with parchment) for up to 3 months and thaw them at room temperature.
- I don’t reheat them, but leaving them out for a bit after refrigeration brings back a great texture.
FAQs
What if my no-bake cookies don’t set?
That usually means they didn’t boil long enough. I always make sure to boil for a full 60 seconds after it reaches a rolling boil.
Can I use old-fashioned oats?
Yes, I use them sometimes for a heartier, chewier cookie. The texture changes a bit, but they still taste great.
Do they have to be refrigerated?
No, they set well at room temperature. But I sometimes chill mine for a firmer bite.
Can I freeze leftovers?
Absolutely. I freeze them in airtight containers for up to 3 months. Thawing them at room temperature works perfectly.
How can I make them gluten-free?
I use certified gluten-free oats. Everything else in the recipe is naturally gluten-free.
