Peanut Butter Oatmeal Mug Cake
This Peanut Butter Oatmeal Mug Cake is the perfect way to enjoy dessert for breakfast! Okay, okay, I shouldn’t be encouraging cake for breakfast, but it’s got oatmeal in it and it’s served in a mug. Plus it tastes like peanut butter toast, so hey! Why not!
You see, I make a pretty good argument (it must be the law firm rubbing off on me) and you’re already telling yourself it’s okay to enjoy this little cake with your sweetie and a cup of coffee over the morning paper. And it definitely is, this is your life… it’s time to start living it right! And by right, I totally mean cake for breakfast!
A lot of people might say mug cakes are out, but guess what, they’re great for people like me with no self-control when it comes to sweet stuff. Mug cakes are the perfect fix when you just need a little something!
This is a double batch mug cake, making it perfect to enjoy with that special someone, Valentine’s Day is approaching after all! A light and fluffy old fashioned oatmeal cake with a rich peanut butter center, it tastes just like peanut butter toast! But feel free to cut the recipe in half to enjoy a smaller portion!

Peanut Butter & Oatmeal Mug Cake for Two
Ingredients
- 6 tablespoons whole milk
- 2 tablespoons vegetable oil
- 2 tablespoons granulated sugar
- 6 tablespoons all-purpose flour
- 3 tablespoons 1-minute oatmeal
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 3 tablespoons peanut butter
Instructions
- Whisk milk, vegetable oil, and sugar together in a 12 oz. or large mug.
- Whisk in the flour until smooth.
- Whisk in the oatmeal, baking powder, and salt until full incorporated.
- Spoon 2 tablespoons of peanut butter on top and push slightly into the batter.
- Microwave on HIGH for 30 seconds, and then in 15-second bursts until the top looks dry and cooked and springs back when pressed with a finger. Mine took about 90 seconds to cook.
- Top with the remaining tablespoon of peanut butter and let stand at least 5 minutes before eating.
Notes
Throw a small handful of mini chocolate chips into the batter for extra fun!

I made this without baking powder because there was none and our microwave isn’t digital so there was no way I could do 30 and 15 seconds. Had to turn the knob to 1 minute. It’s a tad dry but still delish. Thanks for sharing this!

I just made this for breakfast and holy crap is this good. I didn’t have high hopes because most mug cakes I make turn out terrible, but this is delicious! I used a maple & brown sugar oatmeal mix and maple peanut butter for this, so its nice and extra sweet!
