If you’re in the mood for a special breakfast (or dessert) treat, then I implore you to try out this super yummy chocolate oat mug cake.

Now I don’t know about you, but I’m kinda big on sweets. Let me rephrase that, I’m big on sweets in moderation.

You’ll find this mug cake to be all that it should be. It’s moist, super chocolatey, and yet still healthy. Don’t worry – no cause for guilt eating this for breakfast. Or any other time..

*By the way, this cake makes two small servings. Or one large serving all to yourself, that is…*

Limit Your Sugar Intake if You Can

Yes, I do admit to having a sweet tooth; but as long as what I’m eating is not too sweet.

Hence, this chocolate oat mug cake doesn’t contain refined sugar. But you can still use regular sugar if that’s what you usually use..

There’s just enough sugar to where it’s not an overload of sweetness. But you can definitely add in more if you want to after testing it.

Try Out These Low-Sugar Recipes

You really don’t need to add a whole lot of sugar for something to taste good, honestly. And the true flavor of a food really shines through without masking it with the sweetness of sugar.

During my recipe creating process, I don’t just use add a huge amount of sugar. I usually add it in small amounts until I’m satisfied with the results overall.

These delicious chocolate dairy-free waffles are an example. Also check out this amazing low-sugar whole-wheat chocolate chip mug cake recipe. Warning: they’re both so good!

Adding Sugar

I’m a fan of savory food as well as sweet food. Oftentimes though, I choose to sit down with a bowl of cereal.

Mind you, I love a bowl of cheesy grits too! For the most part, it’s best to eat cereals such as whole-grain and fiber that are somewhat low in sugar.

Now if you have to add sugar to a bland bowl of cereal, please do. I find myself doing this often, as some of my favorite cereals are super low in sugar. Just try not to dump it all in there if you can.

Try adding about a teaspoon at a time until it reaches the level of sweetness you desire. At least, that’s how I do it. This helps to reduce the amount of sugar you’re adding.

Chocolate Oat Mug Cake Ingredients

You only need simple ingredients to make this mug cake. And it’s so easy to make as well.

  • All-Purpose Flour: I haven’t tested this recipe with another flour. But there’s nothing wrong if you’d like to experiment with another one.
  • Salt
  • Baking Powder: This is where all that chocolate flavor comes from. And it’s healthy too.
  • Baking Soda
  • Cocoa Powder
  • Oats: Recommended over rolled oats – due to the small size of this mug cake.
  • Coconut Sugar: I used this sugar because the flavor goes well with chocolate. In addition, it has a lower glycemic index than regular sugar. You can also use regular sugar if you prefer..
  • Ground Flaxseed (optional): This is very good for you as it contains omega-3s. Can’t have enough of that!
  • Vanilla Extract: Without this, this cake won’t have as much flavor (at all).
  • Apple Cider Vinegar: This secret ingredient adds to all that fluffy and soft texture.
  • Light Oil: You really don’t have to add any oil if you prefer not to. It’s a very small amount, but it gives the cake a more richer taste, IMO (in my opinion).
  • Milk: You can use regular or dairy-free milk for this recipe. Anyone can enjoy this cake – vegan or not.
