I remember one evening, sitting at my desk surrounded by a jumble of notes and half-finished ideas, when the craving struck. Not just for any snack, but something warm, peanut buttery, and just a little sweet. I didn’t want to dig out a whole batch of cookies or wait for the oven to heat up. So, I tried this single serving peanut butter cookie recipe that cooks right in the microwave. The smell was immediate—the rich peanut aroma filling the kitchen, mixing with a hint of vanilla. It wasn’t perfect; I accidentally left it in a few seconds too long, making the edges a bit crispier than I intended, but that slight crunch added a nice contrast to the soft center. It felt like a small victory against the chaos of the night, a moment of calm and sweetness in just six minutes.

Instructions

In a small bowl, combine 2 tablespoons creamy peanut butter, 1 tablespoon granulated sugar, and 1 tablespoon brown sugar. Mix well until smooth.
Add 1 tablespoon all-purpose flour and 1/8 teaspoon baking soda to the peanut butter mixture. Stir until fully incorporated.
Add 1/8 teaspoon vanilla extract and 1 tablespoon beaten egg to the mixture and stir until a dough forms.
Line a microwave-safe plate with parchment paper or lightly grease it.
Scoop the dough onto the prepared plate and flatten it gently into a cookie shape about 3 inches in diameter.
Microwave on high for 45 to 60 seconds until the cookie is set but still soft in the center.
Allow the cookie to cool for 2 minutes before eating, as it will firm up slightly.

Kitchen Notes: I usually just use a regular microwave-safe plate, nothing fancy. If you want, try serving it with a small scoop of vanilla ice cream or a drizzle of honey for an extra touch—though it’s pretty great on its own. Sometimes, I’ve swapped out the granulated sugar for a bit of maple syrup, but I haven’t tested that fully; it changes the texture a little. You could also stir in a few chocolate chips or chopped nuts if you’re feeling adventurous, but it’s just as satisfying plain. And if you want to skip the egg, I imagine a bit of mashed banana or yogurt might work, but I haven’t tried that yet.

FAQ

Can I make this cookie without an egg? I haven’t tested egg-free versions extensively, but you might try mashed banana or yogurt as a substitute. The texture will be a bit different though.

Will the cookie be fully cooked in just one minute? It’s best to watch closely—microwave strengths vary. The cookie should be set but still soft in the center when done.

How should I store leftovers? If you somehow have leftovers, keep them in an airtight container at room temperature for up to two days. A quick 10-second reheat in the microwave brings back some warmth.

Next time you need a little sweet escape, this single serving peanut butter cookie is ready when you are. Go ahead—give it a try and save the recipe for those moments when only a warm, fast treat will do.
