Step into Jessica’s kitchen and let the scent of warm peanut butter and toasted oats wrap around you like a childhood blanket. These Old-School Peanut Butter Oatmeal Cookies are thick, chewy, and crackly-edged—exactly the kind of treat Jessica would sneak you before dinner. Each bite delivers a double hit of nutty richness from real peanut butter and golden-toasted oats, while soft centers stay irresistibly gooey long after they leave the oven.
Imagine the first snap of a crisp edge, the pull of a chewy middle, and tiny pockets of melty sweetness tucked inside. No chilling, no fuss—just one bowl, ten minutes of mixing, and a cookie sheet stands between you and instant comfort. Whether you’re packing lunchboxes, prepping for a bake sale, or satisfying a midnight craving, these cookies are ready to be your new go-to.
👩🍳 Jessica swears by this recipe because it’s foolproof, endlessly riffable, and disappears faster than the dishes get done. One tray out of the oven, and suddenly everyone’s “just passing through” the kitchen. 😉

Here’s what makes these cookies extra irresistible:
👉 Want even more fun? Add chocolate chips or chopped peanuts!
Preheat oven to 175 °C (350°F). Line 3 baking sheets with parchment paper or silicone mats. 🧻🍪
In a large bowl, cream together butter, peanut butter, brown sugar, and white sugar until light and fluffy (about 30 seconds to 1 minute). 🧈🥄
Add eggs one at a time, then stir in vanilla extract until fully combined. ✨🥚
Stir in flour, oats, baking soda, and salt. Mix until just combined—don’t overmix! 🍂🌾
Scoop out cookie dough into golf ball-sized portions (about 8 per tray). 🍪⛳
Bake for 12–15 minutes, until edges are golden and centers are just set. ⏱️
Let cookies cool on the baking sheet for a few minutes, then transfer to a wire rack. ❄️
Enjoy warm with melty centers or store them for later—if they last that long! 😋💛
✅ Use quick oats for that perfect texture — or pulse old-fashioned oats in a processor
✅ Don’t overbake — they’ll continue to set as they cool
✅ Want crispier cookies? Leave them in a few extra minutes
✅ Add-ins: mix in 2 cups of chocolate chips, peanut butter chips, or even M&Ms! 🍫🥜
