Because yes, you can have your muffin and eat it too—in under five minutes.
So You’re Craving Something Tasty but Too Lazy to Spend Forever in the Kitchen, Huh? Same.
Look, we’ve all been there. That weird time of day when you’re hungry but not dinner-hungry, you want something sweet but not junk food, and you’d love to make something from scratch but not, like, a whole baking situation. Enter: the mug muffin—aka the magical snack that’s here to save your hangry soul without requiring a single mixing bowl or ounce of shame.
And don’t even worry, this one’s low-FODMAP, high-protein, and 100% not disgusting. If you’ve been burned by sad “healthy” recipes before (looking at you, dry protein bars), this one’s about to redeem everything. Plus, it has peanut butter, so… it wins by default.
Why This Recipe is Awesome
First of all, it’s idiot-proof. I’ve tested this on zero sleep, in pajamas, while watching true crime documentaries—and it still came out delicious. So unless you forget how to stir, you’re golden.
Second, it’s:
- Microwave-only. No oven. No cleanup. No sweating over baking times.
- Low-FODMAP, so your gut won’t stage a protest halfway through.
- Protein-packed, so you’ll actually feel full (and slightly smug).
- Made with ingredients you probably already have—unless you live solely on cold brew and vibes.
- Ready in like, two minutes. Not an exaggeration.
So yeah. This one’s a keeper.
Ingredients You’ll Need
(You probably already have most of this stuff lurking in your pantry.)
- 1 tbsp peanut butter – The real MVP. Make sure it’s smooth and natural if you’re fancy.
- 1 tbsp maple syrup – The sweet stuff. You can use a little less if you’re not into sweet-sweet.
- 1 egg – Yes, a whole egg. It’s what gives it muffin-y magic.
- 1 tbsp almond milk – Or any non-dairy milk that doesn’t hate your stomach.
- 1 tbsp oat flour – Low-FODMAP and fluffy. Sub below if you don’t have this.
- 1 tbsp vanilla or unflavored protein powder – The high-protein part.
- 1/4 tsp baking powder – Don’t skip this. It’s your muffin’s lift-off button.
- Pinch of salt – Just trust.
- Optional add-ins: chocolate chips (low-FODMAP approved ones), chopped nuts, or a drizzle of extra peanut butter. Live a little.
Step-by-Step Instructions
- Grab a microwave-safe mug. Not a teeny espresso one—go for something roomy. You don’t want muffin batter lava all over your microwave.
- Add the peanut butter and maple syrup. Microwave for 10–15 seconds to melt slightly, then stir until smooth and united in creamy harmony.
- Crack in the egg. Stir again. Yes, with a fork. You’re a rebel, not a dishwasher.
- Pour in the almond milk. Stir some more. It should look like a weird beige smoothie. This is good.
- Add in the oat flour, protein powder, baking powder, and salt. Mix until combined. It’ll thicken up a bit—don’t panic.
- Toss in any optional goodies. Chocolate chips? Go for it. Chopped walnuts? Absolutely. A dash of cinnamon? You overachiever.
- Microwave for 50–70 seconds. Start at 50. Check the center with a spoon. If it looks like soup, nuke it another 10–15 seconds. Muffins don’t like being nuked to oblivion.
- Let it sit for a minute. It’ll firm up a bit while it cools—and also, molten muffin will burn your face off. (Ask me how I know.)
Common Mistakes to Avoid
- Using the wrong mug. If it’s too small, your muffin will rise like a volcano and punish your microwave for your hubris.
- Microwaving too long. You’re not trying to make a protein hockey puck. 60 seconds is usually enough.
- Skipping the baking powder. No lift = sad, dense muffin. Just a blob. A tasty blob, but still.
- Forgetting the salt. Seriously. Just a pinch changes everything.
- Thinking more protein powder = more protein = better. This isn’t math class. That’s a one-way ticket to dry-town.
Alternatives & Substitutions
Because we all run out of stuff. Or have commitment issues.
- No oat flour? Use almond flour or certified gluten-free all-purpose flour. Coconut flour? Nope—too thirsty and ruins everything. Sorry, coconut.
- No almond milk? Use any plant-based milk you tolerate. Rice, soy, macadamia—go nuts (literally).
- Vegan? Try a flax egg! Mix 1 tbsp flaxseed meal + 2.5 tbsp water and let it sit for 5 minutes. Then use like a regular egg. Muffin may be slightly softer, but still delish.
- No protein powder? Just use 2 tbsp of oat flour total. Still yum, just less protein-packed.
- No maple syrup? Honey or rice malt syrup work too (FYI, honey isn’t low-FODMAP in large amounts, so maybe chill on the squeeze).
FAQ (Frequently Asked Questions)
Can I make this ahead of time?
Technically, yes. But it’s honestly best fresh. You could mix the dry ingredients ahead and just add the wet stuff when you’re ready to nuke.
Do I have to use peanut butter?
Nope! Almond butter, sunflower seed butter, or tahini (if you’re feeling fancy) all work.
Is this actually filling, or will I be hungry in 10 minutes?
It’s surprisingly filling—especially with the protein powder. But pair it with a banana or Greek yogurt if you’re really hangry.
What if I don’t have a microwave?
Are you camping? Either way, you can bake it in a ramekin at 350°F (175°C) for about 12–15 minutes. Slightly more effort, but still doable.
Can I double the recipe?
Yeah, but use a bowl, not a mug. Or make two separate muffins. Your microwave has limits, unlike your ambition.
Is this kid-friendly?
Absolutely. Just maybe skip the protein powder for littler kids and go with oat flour instead.
