100 Calorie Brownie
I’m obsessed with this 100 Calorie Single Serving Brownie! If you’re like me then when you make brownies, it’s a batch. There’s 2 of us who live here and the cats can’t eat chocolate, so what do I have to do? Ok, I have to eat them all. Remember these black bean brownies? Yeah, I would eat them all if they were nearby!
I mean if not, they go bad and we wouldn’t want that. I mean, ok, I could share with friends, but I could also not share with friends and just eat them all myself. This is great, but also very bad.
Healthy Brownie Recipe
So what do you do when you want a brownie but you don’t want to make a entire batch to prevent the guilt? You make single serving 100 calorie brownies! You microwave them and they’re done in a minute.
These will hit your chocolate craving without the guilt – isn’t that the best?
A few more facts on these brownies:
They are really good. Last winter these were our post dinner, dessert favorites.
These are made with applesauce, no oil. I recommend my home applesauce recipe here. Yum!
If you want to make your brownie slightly more creamy, then add a teaspoon of Nutella. Yes the calories will go up a bit, but it’s still much healthier than the usual brownie.
You can easily freeze them. Directions are at the bottom of this post!
Did you guys know how easy powdered sugar is to make? I had no idea! I always like to sprinkle a little powdered sugar on top of my sweets. For 1 cup of powdered confectioners sugar: 1 cup regular sugar + 1 tablespoon cornstarch. Just blend it up until it’s powdery. Boom! Powdered Sugar!

Absolutely. If you want to make a few of these to keep on hand, make as instructed in the recipe and then pop them into freezer bags! When you want to eat one, heat the frozen brownie in the microwave for about 15 seconds.

Just stumbled across this recipe. Is the flour all-purpose or self-rising?
zoe says
i’m the laziest person on earth, so i’ve been looking for a mug recipe just like this! i cannot wait to make it! thank you tons!!
Vidushi says
I accidentally stumbled upon this recipe and wow my mind is blown. I didnt have applesauce nor yogurt so I used like 1/8 tsp of nutella and less than 1/2 tsp sugar and substituted with millet flour. Added almond milk for mixing the ingredients as it was all dry but WOW it cooked to be so soft and spongy! Though it wasnt sweet so took like miniscule ice cream and viola all balaned! Thankyou! <3
Hannah says
I’m always skeptical about these low-cal mug dessert recipes, but this tasted absolutely delicious. I added some Nutella (1/2 tsp instead of 1) and sprinkled powdered sugar on top as suggested – it definitely hit the spot!
Pamela says
So happy to hear you liked this mug brownie! Thanks for commenting Hannah!
Shirley says
This is so perfect. I used 1 packet stevia instead of sugar and added 1-1/2 teaspoons crunchy peanut butter. Perfect. Have made this several times. Loved it each time. Thank you.
Monica P says
I made this the instant I saw it, and wow!! This is amazing for a 100 calorie snack. I have a sweet tooth and it definitely satisfied my craving. Thank you!
Pamela says
Hey Monica, I’m so happy to hear this helped your craving! 🙂 Thank you for commenting!
Amy Morales says
Just started my weight loss journey and I have such a killer sweet tooth. This is perfect for when I want something sweet! I added about a tsp of chocolate chips, so it’s a little over 100 cals, but it’s worth it for me to fulfill that craving without going overboard! Thank you!
Pamela says
Hey Amy, I’m so happy you liked this brownie and it helped your sweet tooth! Best of luck to you!
Emilie says
I just made this with yogurt instead of apple sauce and it was really delicious! I also used stevia because I like the taste. The texture was very thick and fudgy, as a brownie should be (some low-cal mug brownies are really cakey). Thank you so much!
Michelle says
Thank you so much for this! I’m currently pregnant and am trying to cut back on my calories as I was eating too much chocolate and this is enough to satisfy my craving. I used gluten free flour and coconut sugar and it came out so yummy!
Pamela says
Hey Michelle, I hear you on the cravings (8 months pregnant here!). I’m happy to hear you liked this, thanks for commenting and best of luck! 🙂
Kafs says
This recipe is amazing! Some low-calorie mug cakes call for artificial sweetener, and to me, that is all you can taste. This recipe uses normal ingredients and tastes so good! I can have one anytime I want and feel like I’m cheating. Thank you!
Pamela says
Hey Kafs, I’m glad you found this recipe and like it! Keep on enjoying, it’s almost guilt free. 😉 Thanks for commenting!
Roland says
This was DELICIOUS! I did only 1/2 tbsp sugar, and added a tsp Nutella as suggested.
Only needed 45 seconds in the microwave.
Stunning, bookmarked, will make this again! Thanks for sharing!
Pamela says
Hey Roland, I’m SO happy to hear you liked this brownie! Thanks for commenting! 🙂
Nadia says
Can I replace applesauce with yogurt. We don’t get applesauce where I’m from 😍love the idea of a single serving and 100 cal. Cal counting here
Pamela says
Yes, you absolutely can use yogurt instead! It will create a creamy brownie! Enjoy!
Roland says
Here neither, we make our own applesauce 🙂
Diane O'Rourke says
Can you tell me how many carbs are in the brownie?
Thank you.
Beth says
This is a really yummy desert and so filling we put a little cream on it. I wonder if you could do a small tin in the oven. Anyway thanks so much
Daniel says
if you want to bake this in the oven, what temperature should you use and how long should you bake it for?
Pamela says
Hey Daniel, I’ve never baked it in the oven but if you scroll up there are so comments that people have successfully!
Daniel says
do you use sweetened or unsweetened applesauce?
Pamela says
Hey Daniel, in general I prefer unsweetened applesauce – plus it’s less calories.
Dee says
Have you ever cooked these in the oven? If so, what temperature and how long?
Maureen Jasovsky says
This looks really good. What size is the cup that you put the brownie mixture in?
Pamela says
Hey Maureen, mine are about 3.75-4 inches. Enjoy the brownies!
Sia says
What can I replace apple sauce with?
Pamela says
Hey Sia, you could use banana puree or oil but the calories will slightly change. Enjoy!
Orange says
Can you use caramel syrup instead of apple sauce?
Pamela says
I wouldn’t recommend using caramel syrup instead of applesauce. It will raise the calories, and the liquid won’t bake the same.
Tory says
I have to say, I was skeptical about this since I’ve tried so many single serving desserts, but this one “takes the cake” ? I did add a dash of maple syrup since my applesauce was unsweetened. So good!
Pamela says
Hey Tory – that makes me so happy to hear! Glad you enjoyed this brownie – thanks for letting me know!
Alyssa says
I find that adding a splash of vanilla takes this recipe to the next level!
Pamela says
Yum, I will try that Alyssa!
