This single serve peanut butter cookie is simple, easy, and a reasonable size. No need to practice self-restraint when you’re making only one!
I love single serve desserts – I have very little self-restraint with sweets, so any built in way to stop myself from inhaling 2/3 of a batch of cookies is a welcome help. Plus, if you’re making single serve desserts it means that every single time you make and eat one, it’s fresh baked and warm from the oven. Yes. Please. Peanut butter cookies are second in my life only to chocolate chip cookies (that will always and forever have my heart), so when one day the craving struck I found myself at a loss looking for a single serve peanut butter cookie. All the recipes I found either had a weird amount of ingredients or were ridiculously huge. Seriously, I don’t need to eat 1/4 of peanut butter right before bed, as much as I would like to. So I took a few different recipes and crafted my own reasonably sized one. I hope you enjoy it as much as I admittedly have been loving it!
Single Serve Peanut Butter Cookie
2 TBS peanut butter*
2 TBS brown sugar
1/8 tsp baking soda
1/2 TBS beaten egg**
Optional : 2-3 TBS mix-ins, see notes.
Preheat oven to 350 and line a baking sheet with parchment paper, silpat, or spray directly with nonstick cooking spray. Combine all ingredients in a small bowl and stir until totally combined. If using, stir in mix-ins. Scoop batter onto the baking sheet and press down/even it out a bit. Bake 8-12 minutes until totally set and golden brown. Keep a very close eye on it. Once out, allow to remain on tray for 5 minutes before enjoying.
* I use natural peanut butter with no sugar added. Keep in mind that you may want to reduce the sugar a bit if you’re using pb with added sugar.
**If your measuring spoons don’t include 1/2 tablespoon, I find that scooping the beaten egg up with a tablespoon never fills the entire thing and you’ll be left with about a half of a tablespoon. You can also do 1.5 teaspoons – it’s the same thing.
Mix-Ins Note: I’ve been digging normal chocolate chips, but I’ve also done a combo of white chocolate chips (dark chocolate would be great too!) and Craisins, sprinkles, chopped nuts.. whatever suits you! The pictures one is mini chips. 
Oh, and did I mention it makes a perfect snack with a glass of milk?

I do love single serving desserts! I don’t have much restraint either! I love the simplicity of this- can’t go wrong with a simply peanut butter cookie.
Morgan says
That’s how I feel – PB is always a safe option!
Stefani @ Crafty Christian says
This is great! My biggest problem with sweets is the self control, because sugar is so addicting! I’m saving this recipe 🙂
Morgan says
It reall yis! I keep saying I should do a sugar detox, but it;s so tasty!
Ellie says
Yum! Great idea Morgan. My favorite cookie is an Oreo. It’s so classic and delicious 🙂
Morgan says
Can’t go wrong with an Oreo!
Carolyn says
This is genius! I had only ever seen recipes for single serve microwave cakes/brownies. But cookies? Pinning this!
Morgan says
So glad you dig it! I’m never a huge fan of the texture of microwave treats, so this cookie is my dream come true!
Kristy @ Southern In Law says
Yum, yum, yum! Definitely the perfect treat option! xo
Morgan says
Nothing better than a single serve treat in my opinion!
Samantha says
This is perfect for people like me that have to have several cookies in one sitting. 🙂 I will have to try this.
Morgan says
I’m in the same boat as you – I can’t stop at one unless there is ONLY one!
Jessie @ The Acquired Sass says
I have NO units of self control, which is why stuff like this is great for me. I never buy cookie dough because I would eat it all raw in one night. And, I truly don’t even keep most baking ingredients at my own house. I stock the BF’s house instead, so I can’t even bake unless I’m there.
Morgan says
Yesss to raw cookie dough! And I totally get not having baking things in the house. So tempting to just whip something up!!
Laura Bailey says
Oh boy, this is too easy. It could be dangerous! Peanut butter cookies are my favorite!

I’d be lying if I said I haven’t made this recipe multiple, multiple nights in a row, ha!

I’ve never heard of a single sized dessert before, but I can tell you I’m drooling over this now!
Morgan says
They’re awesome! Perfect mix of deliciousness and self control!
Emily says
Hehe, I think that’s my favorite part about all the 1 serving mug cakes and cookies. 🙂 Once you’re done with one, you’re done. 🙂
Morgan says
Yes! Built in restraint!

Yum! Sometimes you just need a peanut butter cookie to hit the spot! 🙂

Laura Hicks says

Yum yum YUM! This looks heavenly! I mentioned this recipe to my friend and her eyes got HUGE! She doesn’t have a lot of time or space to bake. So, this is right up her alley!
Morgan says
Oh, I hope she enjoys it! I have a small house as well and single serve desserts are definitely a godsend!
Michelle says
Confession…I am a Cookie Monster. I would not be able to eat just one of these. Love the concept! Chocolate chip cookies are my favorite.
Morgan says
The only thing that keeps me from eating multiple cookies in one sitting is cooking one at a time!

Morgan, I think you’re absolutely brilliant. The mass of making cookies is what stops me most times. And the fact that you have to stand there tray after tray after Trey. It gets old after the first one. My daughter is going to love this she loves to have a snack when she gets home from school and this will be perfect, she only wants just one thing to take the edge off till dinner and I think this is it.
You asked what my favorite kind of cookie is, and I would have to say my favorite kind of cookie is the one that’s coming fresh and hot out of the oven. One that is sitting under a scoop of vanilla ice cream and a little chocolate drizzle. But only occasionally, LOL.
