Ingredients
The Core Ingredients
- ½ cup (1 stick / 113 g) unsalted butter
- 2 cups granulated sugar
- ½ cup whole milk (or canned coconut milk for extra richness)
- ¼ cup unsweetened cocoa powder
- ½ cup creamy peanut butter (use standard, no-stir)
- 1 teaspoon vanilla extract
- 3 cups old-fashioned rolled oats (not instant or steel-cut)
Optional Add-Ins
- Pinch of flaky sea salt (for topping)
- ½ cup chopped peanuts or mini chocolate chips
- 1 tablespoon chia seeds or ground flax
How to Make No-Bake Chocolate Peanut Butter Cookies
Step 1: The Crucial Boil
- Line two baking sheets with parchment or wax paper. Measure all ingredients before starting.
- In a medium heavy-bottomed saucepan, combine butter, sugar, milk, and cocoa powder.
- Bring to a full rolling boil over medium heat, stirring constantly.
- Once boiling, set a timer and boil for exactly 60 seconds, continuing to stir.
⚠️ This step is critical. Less time = sticky cookies. More time = crumbly cookies.
Step 2: Mix It All Together
- Remove the pan from heat.
- Immediately stir in peanut butter and vanilla until smooth.
- Add oats and mix until fully coated and glossy.
- Fold in any optional add-ins if using.
Step 3: Drop & Set
- Drop heaping tablespoons of the mixture onto prepared baking sheets.
- Sprinkle lightly with flaky sea salt if desired.
- Let cookies cool at room temperature for 30–60 minutes, until fully set.
Pro Tips for Perfect No-Bake Cookies
- Use old-fashioned oats only – quick oats get mushy; steel-cut won’t soften
- Stick to the 1-minute boil – use a timer, not intuition
- Choose conventional peanut butter – natural varieties can prevent setting
- Heavy-bottom pans matter – they prevent scorching and uneven boiling
- Add chocolate chips last – so they don’t melt into the mixture
Serving & Storage
- Serve: At room temperature with a cold glass of milk
- Store: Airtight container at room temp for 1 week or refrigerated for 2 weeks
- Freeze: Up to 3 months layered with parchment
- Gift-Ready: Stack in cellophane bags or tins—always a hit
