How to Make Single Serve Peanut Butter Cookie
Step 1: Preheat Your Oven
First things first: set your oven to 350°F (177°C). Giving your oven a few minutes to heat up ensures your Single Serve Peanut Butter Cookie bakes up evenly, with crispy golden edges and a soft center every time.
Step 2: Mix the Wet Ingredients
In a small mixing bowl, combine the brown sugar, granulated sugar, egg yolk, melted butter, and creamy peanut butter. Give everything a good stir until the mixture is completely smooth. This step lets the sugars dissolve into the fats, setting the tone for a luscious, well-blended dough.
Step 3: Add the Dry Ingredients
Sprinkle in the all-purpose flour and baking soda. Mix gently until no dry streaks remain and the dough has a thick, scoopable consistency. Be careful not to overmix—just combine enough to create a unified dough.
Step 4: Shape and Prep for Baking
Lightly grease a 10-ounce ramekin and spoon in your dough. Smooth it out to the edges so it bakes evenly. For a little sparkle and extra crunch, sprinkle the reserved ⅛ teaspoon of granulated sugar over the top before it goes into the oven.
Step 5: Bake to Perfection
Place your ramekin on the center rack and bake for 12 to 15 minutes. You’ll know it’s ready when the top looks lightly golden and the edges are set, but the center still looks just a touch soft—that’s your cue for chewy, cookie bliss! Let it cool for a couple minutes before diving in.

Garnishes
Dress up your Single Serve Peanut Butter Cookie with a scoop of vanilla ice cream, a drizzle of warm chocolate sauce, or a sprinkle of flaky sea salt for an extra punch of flavor and color. Fresh berries or a few chocolate chips pressed gently on top right after baking also add a playful twist.
Side Dishes
This cookie is a star on its own, but if you want to take things up a notch, pair it with a cup of hot coffee, a glass of cold milk, or your favorite herbal tea. The nutty richness is just begging for a cozy beverage companion.
Creative Ways to Present
The beauty of this Single Serve Peanut Butter Cookie is its versatility. Serve it straight from the ramekin for a rustic, cozy look, or carefully unmold it onto a small plate and add a dusting of powdered sugar for a more polished feel. You can even cut it in half and sandwich a little ice cream in the middle for an impromptu cookie sandwich!
Make Ahead and Storage
Storing Leftovers
If, by some miracle, you don’t finish your Single Serve Peanut Butter Cookie in one go, just cover the ramekin with plastic wrap or foil. It’ll stay soft and chewy at room temperature for up to two days. A quick zap in the microwave brings back that fresh-baked magic.
Freezing
Want to get ahead of your cravings? You can freeze the baked cookie tightly wrapped for up to a month. Thaw it overnight or give it a short microwave burst when you need a speedy treat. Alternatively, freeze the raw dough in the ramekin, then bake straight from frozen—just add an extra minute or two to the bake time.
Reheating
For that just-baked warmth, pop your Single Serve Peanut Butter Cookie in the microwave for about 10-15 seconds. This revives the gooey center and reactivates all those scrumptious peanut butter aromas—it’s like pressing the reset button on your treat!
FAQs
Can I use crunchy peanut butter instead?
Absolutely! Using crunchy peanut butter will add a little extra texture and a pleasant nutty crunch to your Single Serve Peanut Butter Cookie without changing the basic recipe steps—just be sure to spread it evenly in your ramekin.
What if I don’t have a ramekin?
No worries—any small oven-safe dish will work, such as a mini pie dish, a small ovenproof bowl, or even a well-greased mug. Just ensure it holds about 10 ounces for the best results.
Can I make this recipe gluten-free?
Yes! Swap the all-purpose flour for a gluten-free blend (one that subs cup-for-cup). Your Single Serve Peanut Butter Cookie will come out just as tender and full of peanut buttery joy.
Is there a way to make it vegan?
Certainly—replace the egg yolk with a tablespoon of unsweetened applesauce and use vegan butter. The result is still rich, chewy, and packed with that classic peanut butter flavor.
Can I double the recipe?
Of course! Simply double everything and divide the dough into two ramekins (or use one medium oven-safe dish). Bake as directed, but keep an eye on them—a slightly longer baking time might be needed for larger portions.
Final Thoughts
