Ingredients in Low-Carb Pumpkin Mug Cake
It’s really easy to make a delicious keto mug cake. The great thing about this pumpkin cake is that it uses common keto ingredients. And, keto mug cake doesn’t require any special equipment — so as long as you have a mug, a whisk, and a microwave, you’re ready to go.
If you’ve been following the keto diet for a while, you probably have everything you need in your pantry already. Along with grocery staples like butter, salt, baking powder, and an egg, you’ll also need:
- almond flour
- coconut flour
- erythritol sweetener, like Swerve brand
- pumpkin puree, canned or fresh homemade
- pumpkin spice blend, OR cinnamon, nutmeg, ginger, and cloves
Almond Flour is a common keto flour that substitutes for traditional wheat flour. For best results, find a blanched almond flour with a super-fine texture.. I like Bob’s Red Mill or Anthony’s brand almond flour.
Coconut Flour is another common low-carb baking ingredient. Coconut flour is made from ground and dried coconut meat. Because it’s so high in fiber, it’s super absorbent. So, a little bit of coconut flour goes a long way.
Low-Carb Sweetener. I tend to stick with erythritol based sweetener like Swerve. The “brown sugar” version of Swerve would be particularly delicious in this recipe. But you may want to experiment with other sweeteners like xylitol or allulose. (Remember that allulose is less sweet than erythritol, so you’ll need to use more than the 2 tbsp called for in this recipe.)
Pumpkin Puree. Pumpkin is a nutritional superstar: it’s low in calories, high in fiber, and provides more than double your daily dose of Vitamin A in just one serving. You can use either canned pumpkin puree or homemade pumpkin puree in this recipe. Just make sure you’re not using pumpkin pie filling, which can be easy to grab by accident at the grocery store.

How to Make Keto Pumpkin Mug Cake
When I say that this is a quick and easy recipe — I really mean it. It’s perfect to make for an after-dinner snack when you don’t feel like turning on the oven.
It’s so fast. Once you have the ingredients gathered, the whole recipe takes 2-3 minutes from start to finish — and that includes the cooking time!
To make the pumpkin cake batter, what you’ll do is just stir all of the ingredients together in a large mug. And then to cook it, just zap it in the microwave for a minute or two. And ta-da! You have your healthy pumpkin mug cake, ready to enjoy.
Let’s break down the steps. I start out by melting 2 tablespoons of butter in a large mug. To that, I add an egg, the pumpkin puree, and a small splash of vanilla extract. I stir it well with a fork, or a small whisk if it’s handy. I do spend a little bit of time mixing up the egg, just to make sure I break up the egg white.
Then, I add the rest of the dry ingredients — almond flour, coconut flour, sweetener, salt, spices, and baking powder — and stir well to combine. Then, all that’s left to do is pop it in the microwave.
I microwave on high for about 1 minute and 30 seconds. You’ll see the batter rise up in the mug. When the top looks set — but not too dry! — you’ll know the mug cake is done. You can also test the cake by touching the top. It should be firm and a little springy.
Depending on the size of your mug and the strength of your microwave, you may need to microwave this mug cake for a little bit longer. If the mug cake still looks undercooked after 90 seconds, you can put it back in the microwave for an additional 30 seconds. But be careful not to overcook the mug cake — you don’t want it to be dry!
How to Make Moist Keto Mug Cakes
Here are some tips to make sure you end up with a warm, moist, and fluffy keto mug cake every time.
- Choose the right mug. I like to use a larger, wide mug shape with straight sides. Tall, skinny, or super curvy mugs can make it difficult for the cake to cook evenly in the microwave. You definitely don’t want the cake to overflow a too-small mug halfway through the cook-time, either!
- Mix the ingredients well. You can mix all of the ingredients in the same mug that you cook the cake in — that means less dirty dishes to clean later! But, if you do that, make sure to take extra care to scrape the sides and bottom of the mug so that all of the ingredients are incorporated fully. In particular, make sure to break up that egg white so you don’t get little pockets of cooked egg white in your cake. If you don’t mind an extra dish, you can also mix all the ingredients in a separate mixing bowl and then pour it into a mug to cook it – your choice!
- Try not to overcook the cake. Every microwave is different, so you may need to make this mug cake a couple of times to find the perfect cook time for you. I find that 90 seconds is a good starting point. You can check the cake by carefully touching the top. The batter should be set and slightly firm. If the batter is still wet, you can keep cooking in 20-30 second bursts.
