I LOVE a single serve dessert! My go-to is usually either my single serve gluten-free cinnamon roll, or if I need some extra protein I’ll quickly throw together a single serve protein cookie. But lately, I’ve been alllll about this 3-ingredient peanut butter mug cake. I love that I can take it straight out of the microwave and onto the couch with me, and enjoy it warm (!!!) while I binge whatever show I’m watching that week. I typically enjoy it all on its own, but if I’m feeling crazy I’ll add a scoop of vanilla ice cream, a drizzle of chocolate, or even a handful of sprinkles! Please, have fun with this recipe, and most importantly – ENJOY!

What You’ll Need to Make Peanut Butter Mug Cake
Egg: The egg acts as a binder, giving the mug cake its structure and fluffy texture. I wouldn’t recommend trying to replace the egg with something else, since it’s vital to holding this mug cake together.
Peanut Butter: Adds richness, a nutty flavor, and protein to the cake. Use creamy or natural peanut butter for best results. However, if you can’t have peanut butter use any nut, seed, or granola butter in its place!
Sugar: Sweetens the mug cake. Adjust the quantity based on your taste preference or use alternatives like coconut sugar for a refined sugar-free option!

How to Make Peanut Butter Mug Cake
- Start by cracking an egg into a microwave-safe mug.
- Add the peanut butter and sugar, then mix well until smooth and lump-free.
- Microwave for 1 minute. Check the texture; if it’s undercooked, microwave for an additional 10 seconds.
- Allow to cool slightly, then enjoy it straight from the mug!
Topping/Mix-In Options
- Chocolate Chips: Sprinkle a few on top before microwaving for a melty chocolate finish.
- Banana Slices: Add a natural sweetness and pair perfectly with peanut butter.
- Crushed Nuts: For extra crunch, sprinkle chopped peanuts or almonds on top.
- Drizzles: Drizzle with honey, maple syrup, or melted chocolate after cooking.
Sam’s Recipe Tips
- Microwave Timing: All microwaves vary in power. Start with 1 minute, then check and add time in 10-second increments if needed.
- Texture: For a gooier center, slightly undercook the cake by a few seconds.
- Peanut Butter: Natural peanut butter may result in a slightly denser texture but works perfectly. Stir well before using to incorporate the oils.
Why This Recipe Stands Out
This mug cake is:
- Healthy
- Naturally high in protein
- Gluten-free
- Dairy-free
- Made with just 3 simple ingredients
It’s a perfect quick dessert or snack that’s as easy as it is delicious!
