Oat Fiber Chocolate Muffins are low calorie chocolate muffins made with oat fiber, an ingredient often used in keto baking. I don’t do a lot of keto baking, but I always have oat fiber and like using it to add bulk and cut calories in recipes. This is one of my favorites. These muffins weigh about 2.6 ounces each, and according to My Fitness Pal have a calorie count of around 150. That’s pretty good for a large chocolate muffin!

Oat Fiber Chocolate Muffins Count
I’ve been fiddling with this muffin recipe for a while, so I’m really looking forward to hearing how it works for others. I use fairly large (but not jumbo) muffin papers and make 5 muffins. There’s enough batter to where you could make 6, but I like the muffins a little larger.
Ingredients
- All-Purpose Flour — Just plain old AP flour, but you could probably substitute bread flour or even whole wheat without any problems.
- Oat Fiber — I always use Anthony’s brand. Last time I checked they were sold out, so you may have to try a different brand. This is one ingredient I’ve never seen in stores, though I’ve heard rumors of it making an appearance at Kroger. And just in case you didn’t already know, oat fiber is not the same as oat bran or oat flour and can’t be used interchangeably.
- Unsweetened Cocoa Powder — Hershey’s (natural) but Dutch should be fine too.
- Allulose — Wholesome Sweeteners. If you use Swerve, the muffins might be slightly sweeter. I’ve only tested with a mixture of allulose and sugar.
- Sugar
- Baking Powder
- Baking Soda
- Salt
- Applesauce — Unsweetened. I buy it in individual serving cups so I can use small amounts at a time for baking.
- Egg White
- Greek Yogurt — Any type should be fine, but I use plain whole milk Greek yogurt.
- Brewed Coffee — For more coffee flavor, you could use a teaspoon of espresso powder and 2 1/2 oz of water. If you don’t drink coffee, I’m pretty sure 2 1/2 oz of warm water would work just as well.
- Vanilla Extract
- Chocolate Chips — Most of the calories in this recipe come from the chocolate chips. 1/3 cup is about 2 oz, so these are pretty chocolaty! I use regular semisweet chocolate chips or sometimes Lily’s sugar free., which aren’t that much lower in calories. If you want to go crazy cutting the calories, you could try using something like Gatsby’s dark chocolate, which is a new chocolate that is actually low in calories. I haven’t actually tried it yet, but I ordered some. Update: Just got some Gatby chocolate in the mail and it is insanely good!
