A traditional apple pie mug cake really is just cake – loaded with sugar and fat. It’s not unusual for one of those single-serving desserts to hit 500 to 600 calories. Not exactly healthy. And definitely not helpful for fat loss.
This apple pie protein mug cake is different. It takes just 5 minutes to prep and 1 minute in the microwave, and it delivers 35 grams of protein in a single serving. I cut the calories at least in half, boosted the nutritional value, and kept the macros fat-loss-friendly – all while preserving that warm, classic apple pie flavor.

Once again, the Burn the Fat Blog mission accomplished! This apple pie protein mug cake has only 263 calories, yet it has a full meal’s-worth of protein (35 grams per mug cake).
Why This Apple Pie Protein Mug Cake Has 35g of Protein
The high protein count comes mainly from the vanilla whey, which contains 24 grams of protein per serving. (Usually 31 grams of weight per scoop or approximately 1/3 cup). The rest of the protein is from egg whites, greek yogurt, and there’s even a little in the flour.
All those ingredients combined get you a full meal’s worth of quality protein (which you rarely see in a snack or dessert).
A few companies make apple pie or apple cinnamon flavored whey. If you can find it, that would probably taste great. But vanilla works nicely, and is more widely available.
Best Flour Options For Mug Cake
I’ve tried a few different flours and even combining various types and the taste is still similar. If you don’t have oat flour on hand (one of my favorites), all-purpose flour works fine.
Oat flour is widely available at health food stores, and on at Amazon as well. Arrowhead Mills and Bob’s Red Mill are popular brands.
How To Get Real Apple Pie Flavor
The apple flavor comes from the applesauce (which by the way is a one-for-one fat alternative when you are baking light and wanting to save on calories). Add cinnamon to your liking. I usually use 1/2 a teaspoon (at least 1/4 teaspoon recommended), reserving a little more for sprinkling on top.
For a while I made these without whole fruit, but I was curious what these might be like with finely diced fresh apple chunks (also sprinkled with cinnamon), so I finally tried it. The mug cake is great without fresh apples, but including them is an improvement! It adds moisture and crunch, plus we can legit say “apple pie” in the name.
Sweetener Options For Healthy Mug Cake
You can avoid calorie-dense refined sugar by using any non-nutritive sweetener you prefer, such as Stevia, Truvia, and so on. A few packets go in the batter and then you can sprinkle a little more on top if you like, for sweetness or presentation. Feel free to adjust the amount to your own tastes.
Gooey Or Cakey: How To Adjust The Texture
Be sure not to overcook as you don’t want it to dry out completely, especially if you want this “gooey” version of the mug cake.
What if you don’t want it gooey? What if you want the whole thing solid like regular cake or a muffin? No problem. Simply omit one ingredient – the Greek yogurt. It’s the yogurt that helps keep the bottom moist and gooey molten.
When you leave out the yogurt, unless you undercook it, the finished product will be mostly solidified and dry, yet with a lightly-moist spongy cake consistency from top to bottom.
Don’t forget that since you’re using baking powder, the cake will rise up in the mug in the microwave, and if your mug is too small, it may rise over the top and spill over the edges. That’s why I like to use a nice big 18 oz mug.
Enjoy Your Microwave Mug Cake!
You can eat this with a fork right out of the mug, or if you want the gooey stuff on top (much better), flip the mug upside down over a plate or ramekin before serving. (Makes for nice presentation too). Then what was the gooey bottom will now be your gooey top, almost as if you had put frosting on it.
Sprinkle some cinnamon and if you choose, additional sweetener on top, and then enjoy this apple pie protein mug cake recipe.
Oh, and in case you’re wondering: Are microwave ovens safe? (what science says)

Is there a way to bake this in a regular oven? Sounds like a Great Treat.
Thanks
I’m sure you can, but I haven’t tried, so at this point I can’t give you a baking time yet… I’ll have to look into that. But hey 60-sec in microwave… can’t beat that…
When will you come up with a vegan recipe?? Some of us bodybuilders are vegan!! On another note, you shouldn’t leave the yolks out of eggs, they have soo much protein and plain whites are like adding “nothing” to the recipe
Hi Jacqueline. I do know some bodybuilders are vegan! Ive got a handful of personal friends and colleagues in the bodybuilding space who are vegan, and I might add, they have great physiques, and I think it’s good to point out that one can build muscle being vegan. Im not a vegan though. Im not even vegetarian, so I don’t do vegan cooking, and so the majority of the recipes in my collection are not vegan. I do have a handful though (I just made a great chickpea salad last week), and quite a few that are vegetarian (meat free) and I can share on occasion, but the recipes on this site won’t be vegan focused. fortunately there must be hundreds of vegan food blogs out there, so there’s plenty of info in that niche. PS I use whole eggs in my recipes all the time – this one just happens to be egg whites only, which I often do if there is little or no difference in flavor or texture and or if I want to save calories. See my article on eggs (just updated) here:https://www.burnthefatblog.com/egg-whites-vs-whole-eggs/
I made a batch of these for some guests the other day. I just multiplied the ingredients by the number of people I was making them for and added it all into 1 bowl. I first tried to pour the mixture from the bowl into the mugs bit it went everywhere! So I used a soup ladle to pour the mixture into the mugs. Much cleaner!
Another time I tried to microwave 2 mugs at once but a minute wasn’t enough time and I had to mess around doing it a bit longer, then a bit longer again. I find it much easier just to do them 1 at a time in the microwave for a minute each.
Thanks for sharing your observations! Yep, mug cakes are pretty much classically made and served as a 1 serving meal. Someone else asked me if you could bake these. I hadn’t tried so I didnt know, but perhaps thats a way to do a batch. But since the nuking time is only a minute, its not that much trouble to do 2, 3, 4 in a row for a hungry group. Cheers!
