Why You’ll Love These Air Fryer Protein Donuts with Cake Mix

• Crumbly-perfect texture: Somehow they’re fluffy and satisfyingly dense. Like if a cake and a donut had a delicious baby.

Trust me, once you try these, that bakery drive-thru won’t stand a chance.

Ingredients for Air Fryer Protein Donuts with Cake Mix

Grab these simple ingredients – I promise you probably have most of them already! The beauty of this recipe is how effortlessly it comes together. Here’s exactly what you’ll need:

• 1 box (15.25 oz) vanilla or chocolate cake mix – Don’t overthink the brand here. That basic box in your pantry? Perfect.
• 1 scoop (30g) vanilla or chocolate protein powder – This is where the magic happens! Use your favorite whey or plant-based powder.
• 1 cup water or milk – Milk makes them richer, but water works great too. (I’ve used almond milk when I’m feeling fancy!)
• 1/4 cup melted butter or oil – Melted and slightly cooled, please! Coconut oil works amazingly if you’re going dairy-free.
• 2 eggs – Room temp if you can plan ahead (they mix better), but straight from the fridge works in a pinch.

See? Nothing crazy or obscure. Half this stuff is probably sitting in your kitchen right now taunting you to make donuts. Let’s do this!

Equipment You’ll Need

No fancy gadgets required here—just a few basics to get those donuts cooking. Here’s your checklist:

• An air fryer – Any model works, but if yours runs hot (looking at you, Ninja users), check the donuts a minute early.
• A donut pan – The 6-cavity silicone or metal kind that fits in your air fryer basket. Pro tip: If yours has awkward ridges, grease it extra well.
• A mixing bowl – Big enough to stir without flour clouds escaping. My “oops” moments taught me that.
• A piping bag or ziplock – For mess-free batter filling. (Snip the corner! No one wants batter explosions.)
• Cooking spray – Non-stick is non-negotiable. Even “non-stick” pans betray you sometimes.

That’s it! No stand mixers, no weird attachments. If you’ve got these five things, you’re minutes away from donut bliss.

How to Make Air Fryer Protein Donuts with Cake Mix

Alright, let’s get down to business! These donuts come together so fast, you’ll wonder why you ever bothered with complicated recipes. Here’s exactly how I make them—every step is foolproof if you follow along.

Step 1: Prep the Batter

First things first: grab that mixing bowl and dump in your cake mix and protein powder. Give them a quick whisk to avoid any sneaky clumps. Now, add the water (or milk if you’re feeling indulgent), melted butter, and eggs. Here’s my pro tip: mix by hand with a spatula just until smooth. Overmixing makes them tough, and we want clouds of joy, not hockey pucks! The batter should be thick but pourable—like pancake batter with a little more oomph.

Step 2: Fill the Donut Pan

Time to channel your inner pastry chef! Spoon the batter into a piping bag or a sturdy ziplock (snip a 1-inch hole in one corner). Spray your donut pan like it’s going out of style—every nook and cranny. Now pipe the batter into each cavity, filling them about 2/3 full. (Trust me, they puff up like they’ve got something to prove!) If you’re a perfectionist like me, use a damp finger to smooth any uneven tops. No fancy tools needed—just enthusiasm.

Step 3: Air Fry to Perfection

Pop that pan into your preheated air fryer at 350°F and let the magic happen. Set your timer for 8 minutes, but peek at the 7-minute mark—some air fryers run hotter than others. You’re looking for golden tops that spring back when lightly pressed. A toothpick should come out with just a crumb or two. If they need more time, add 1-2 minutes, but don’t walk away! These little guys go from perfect to overdone in a flash. Let them cool in the pan for 5 minutes before transferring to a rack. (Patience is hard, but hot donuts are fragile!)

And there you have it—warm, protein-packed donuts ready for glazing, sprinkling, or—let’s be real—immediate devouring. The hardest part? Waiting those 5 minutes before digging in. You’ve got this!

Tips for Perfect Air Fryer Protein Donuts

After making these donuts more times than I can count (research purposes, obviously), I’ve learned a few tricks that’ll guarantee bakery-quality results every single time. Here are my hard-earned secrets:

• Know your air fryer’s personality: Mine runs slightly hot, so I start checking at 7 minutes instead of 8. If yours is newer or tends to cook fast, do the same. Underdone is fixable—burnt isn’t!
• Grease like you mean it: Even “non-stick” pans can betray you. I use both spray and a quick swipe with a buttered paper towel in the crevices. Overkill? Maybe. Stuck-donut-free? Absolutely.
• Cool before glazing (if you can wait): I know, the temptation is real. But 5 minutes of cooling prevents glaze meltdowns and gives the donuts time to firm up. Pro tip: Speed-cool by popping them in the fridge for 2 minutes!
• Protein powder matters: Some brands absorb more liquid. If your batter seems too thick, add a splash of milk. Too thin? A teaspoon of flour saves the day. Texture should be like thick pancake batter—not cement, not soup.

There you go—the kind of tips you’d only learn from someone who’s had (and fixed) every possible donut disaster. Now go forth and fry with confidence!

Ingredient Notes and Substitutions

Listen, I know we don’t all have the exact same ingredients lying around—and life’s too short for extra grocery runs! Here’s how to tweak this recipe without sacrificing those perfect donuts. (I’ve tested all these swaps myself, so you’re in good hands.)

Cake Mix Confessions

That boxed mix is your best friend here, but not all are created equal. Gluten-free cake mix? Works like a charm—just add an extra tablespoon of milk since it tends to be thirstier. Sugar-free mix? Go for it, but your donuts might be slightly denser. (Totally worth it if that’s your jam!) My wildcard move? Using funfetti mix for birthday vibes—just reduce the water by 2 tablespoons because those sprinkles add bulk.

Protein Powder Possibilities

Here’s where things get flexible. Vegan protein powder? Absolutely! I love pea protein here—it blends smoothly. If your powder’s super absorbent (looking at you, brown rice protein), add an extra splash of milk. No vanilla or chocolate powder? Unflavored works too—just bump up the vanilla extract to 1 teaspoon. And if you’re out of protein powder entirely? Sub with 1/4 cup flour plus an extra egg. They won’t pack the same protein punch, but they’ll still taste amazing.

Liquid Swaps That Work

Water’s easy, but milk alternatives shine here. Almond milk makes them subtly nutty, while coconut milk (the canned kind) gives crazy-rich texture. For extra protein, try Greek yogurt thinned with water—about 3/4 cup yogurt + 1/4 cup water. Just avoid juice unless you want oddly sweet donuts (learned that the hard way).

Butter vs Oil Showdown

Butter = flavor, oil = tenderness. Melted coconut oil is my go-to dairy-free swap—it makes the crumb incredibly soft. Applesauce works in a pinch (1/4 cup), but your donuts will be cakier. Pro tip: If using oil, add 1/8 teaspoon salt to balance sweetness. And for the love of donuts, don’t use olive oil unless you enjoy faintly savory desserts (another “oops” moment of mine).

See? No ingredient is set in stone here. The beauty of this recipe is how forgiving it is—as long as your batter looks like thick pancake mix, you’re golden. Now go raid your pantry and make some magic!

Serving and Storage

Oh, the glorious moment when those warm donuts come out of the air fryer—resist the urge to dive in face-first! (Okay, maybe just one bite.) Here’s how to serve and store them like a pro:

Serving Suggestions That’ll Make You Look Fancy

Fresh out of the air fryer, these donuts are heavenly plain—warm, slightly crisp on the edges, and pillow-soft inside. But let’s talk upgrades. For a quick glaze, whisk powdered sugar with a splash of milk until drizzle-able and dunk the tops. Crushed nuts or sprinkles? Yes, please. My gym-buff friends swear by a peanut butter drizzle for extra protein. Kids (and let’s be real, me) go wild when I sandwich two with whipped cream in the middle. Breakfast? Absolutely—call them “protein pastries” and no one can judge.

Storage Secrets for Maximum Freshness

If by some miracle you have leftovers (rare in my house), here’s the deal: let them cool COMPLETELY, then tuck them into an airtight container with a paper towel underneath to absorb moisture. They’ll stay fresh for 2 days at room temp, though texture’s best within 24 hours. For longer storage, freeze them unglazed in a single layer on a tray, then transfer to a bag—they’ll keep for 1 month. To revive, pop frozen donuts in the air fryer at 300°F for 90 seconds. Pro tip: Glaze after reheating unless you enjoy sticky fingers!

Now go forth and serve these beauties with pride—or hide them in your snack drawer. I won’t tell.

Nutritional Information

Okay, let’s talk numbers—because knowing exactly what you’re biting into makes these donuts even more satisfying! Based on my recipe (using vanilla cake mix, whey protein, and whole milk), here’s the breakdown per donut:

• Calories: ~220
• Protein: 10g (hellooo, post-workout fuel!)
• Carbohydrates: 30g
• Sugar: 12g
• Fat: 8g
• Fiber: 1g

Now, full transparency: these numbers will dance around depending on your ingredients. Swap almond milk for whole milk? Subtract about 20 calories. Use sugar-free cake mix? Carbs drop significantly. My rule of thumb? If you’re tracking macros closely, plug your exact brands into an app like MyFitnessPal. But for the rest of us, this is a darn good estimate—and a way tastier option than anything from the drive-thru!

FAQ About Air Fryer Protein Donuts with Cake Mix

Got questions? I’ve got answers—plus a few “learn from my mistakes” gems! Here’s everything you need to know before whipping up these protein-packed treats.

“Can I use gluten-free cake mix?”

Absolutely! I’ve tested this with several gluten-free mixes, and they work like a charm. Just add an extra tablespoon or two of liquid—gluten-free flours tend to be thirstier. Bob’s Red Mill and King Arthur mixes are my go-tos. The texture might be slightly denser but still totally donut-worthy!

“Help—my donuts are sticking to the pan!”

Been there, scrubbed that. First, grease every nook—I mean every crevice—with non-stick spray or melted butter (a pastry brush helps). Second, let them cool for 5 full minutes before removing. Still stuck? Run a butter knife around the edges gently. Pro tip: Silicone donut pans are lifesavers for stick-prone air fryers!

“Can I bake these instead of air frying?”

You bet! Bake at 350°F in a conventional oven for 10-12 minutes. They’ll be slightly softer without that crispy air-fried edge, but still delicious. No donut pan? Spoon the batter into muffin tins (fill halfway) and call them “protein muffins”—same great taste, new shape!

“My batter’s too thick/thin—what now?”

Don’t panic! Thick batter? Add milk 1 tablespoon at a time until it flows like pancake batter. Too runny? Mix in 1-2 tablespoons of flour or protein powder. Different brands absorb liquid differently—trust the texture, not just measurements. (My first batch looked like soup… we don’t talk about it.)

“Can I freeze these for later?”

Oh yes! Freeze unglazed donuts in a single layer on a tray, then transfer to a bag for up to 1 month. To revive, air fry frozen at 300°F for 90 seconds—they’ll taste freshly made. Glaze after reheating unless you enjoy sticky fingers (speaking from experience).
