- Unsweetened cocoa powder, 1/4 cup: Brings deep chocolate flavor without overwhelming sweetness.

How to Make No Bake Cookies — Just Like Grandma’s! Recipe
Step 1: Create the Chocolate Base
Begin by melting the butter in a medium saucepan over medium heat. Once melted, add the milk, granulated sugar, and unsweetened cocoa powder. Bring this mixture to a boil while stirring occasionally, then let it boil for 1 to 2 minutes. This step is crucial because it cooks the sugar enough to achieve that perfect fudgy texture when the cookies set.
Step 2: Add the Peanut Butter and Vanilla
Remove your saucepan from the heat and immediately stir in the peanut butter along with the vanilla extract. Mix until smooth and creamy. This creamy combination is what makes the cookies irresistibly rich and comforting, giving them that dense, just-made feel.
Step 3: Mix in Oats and Salt
Now, the oats and a pinch of salt join the party. Stir everything until the oats are thoroughly coated in the chocolate-peanut butter mixture. You’ll notice the dough become thick and slightly sticky — that’s exactly what you want to ensure each cookie holds its shape once set.
Step 4: Scoop and Shape Your Cookies
Line a baking sheet with parchment paper or a silicone mat for an easy cleanup. Use a spoon to drop generous spoonfuls onto the sheet, spacing them about 2 inches apart. Flatten each dollop slightly with the back of the spoon so they resemble classic cookie shapes. This little step helps them cool and set evenly.
Step 5: Let the Cookies Set
Allow the cookies to cool at room temperature for 30 minutes to 1 hour. If you’re in a hurry, pop the tray into the fridge for faster setting. Once firm, these cookies will hold their shape beautifully while maintaining that soft, chewy texture everyone loves.
Step 6: Enjoy Your No Bake Cookies — Just Like Grandma’s! Recipe
Once set, these cookies are ready to be enjoyed! Whether served as a quick snack or a sweet finish to a meal, be prepared for compliments and requests for seconds. These truly embody the warmth of grandma’s kitchen.
How to Serve No Bake Cookies — Just Like Grandma’s! Recipe

Garnishes
While these cookies are perfect on their own, sprinkling a little extra touch can elevate the experience. A light dusting of powdered sugar or a few chopped nuts on top brings additional texture and a pop of visual contrast that’s hard to resist.
Side Dishes
Pair your No Bake Cookies — Just Like Grandma’s! Recipe with a cold glass of milk for the ultimate classic combo. They also shine alongside a warm cup of coffee or tea, making for a comforting afternoon break that feels like a hug in dessert form.
Creative Ways to Present
For a special occasion, try layering these cookies with whipped cream and fresh berries in a trifle-style parfait. Or serve them sandwich-style with a scoop of vanilla ice cream in the middle for a delightful twist on a cookie ice cream sandwich.
Make Ahead and Storage
Storing Leftovers
Keep your leftovers fresh by storing the cookies in an airtight container at room temperature. They will maintain their perfect texture for up to a week, making them an ideal make-ahead sweet treat for busy days.
Freezing
If you want to save your cookies longer, freezing works beautifully. Arrange them in a single layer on a baking sheet to freeze initially, then transfer to a freezer-safe container or bag. They keep well for up to 3 months and thaw quickly at room temperature.
Reheating
These cookies are delightful cold, but if you prefer a softer bite, give them a quick 10-second zap in the microwave. Just be careful—their chewy charm is best enjoyed without over-warming.
FAQs
Can I use old-fashioned oats instead of quick oats?
Old-fashioned oats will work but will create a chewier, less uniform texture. Quick oats absorb the chocolate mixture more evenly, giving you that classic no bake cookie consistency.
Is it possible to make these cookies without peanut butter?
Absolutely! You can substitute peanut butter with a nut-free spread or sunflower seed butter to accommodate allergies without sacrificing the creamy texture.
Why do the cookies sometimes turn out dry or crumbly?
This usually happens if the mixture is cooked too long or the sugar doesn’t reach the right temperature. Be sure to boil just for 1-2 minutes and stir promptly to combine ingredients smoothly.
Can I add extras like chocolate chips or nuts?
Definitely! Once the oat mixture is combined, folding in chocolate chips, chopped nuts, or even shredded coconut can add fun texture and flavor variations.
How do I know when the cookies are fully set?
The cookies are fully set when they are firm to the touch and no longer sticky. Cooling at room temperature or refrigerating speeds up this process.
