Follow this simple orange mug cake recipe! It makes a single serving orange cake that is gluten-free, high protein, and you can make a microwave chocolate orange cake too!

To make the tastiest orange cake, you want to use both orange zest and orange juice. Fresh orange juice is definitely your best option, so pick up a juicy orange for this recipe. It’s worth it.

To make the zest, get this microplane zester. It is only a few bucks and is totally worth it. It grates oranges, lemons, limes, and you can even use it on ginger too.

Because it grates so finely, you don’t get any of the bitter white part of citrus zest like you can if you’re using a regular cheese grater.

almond flour

melted butter or coconut oil

granulated sugar (plain white sugar, coconut sugar, or keto-friendly sugar like this)

orange juice

an egg

½ tsp baking powder

Orange zest

Since we’re using almond flour for this mug cake recipe, it is naturally gluten-free and high protein. It’s also flourless.

This citrus mug cake tastes the most delicious when you use fresh squeezed orange juice.

But in a pinch you could use any orange juice you have.

Part of the yummy orange flavor comes from the orange zest, so that’s why it’s best to use a fresh orange and zest and juice that baby.

Whaaaack!

What’s that sound?

It’s a Terry’s Chocolate Orange being whacked on a table to break it up into those yummy chocolate orange slices.

This is a classic chocolate that’s around at Christmas time. Oddly enough I have also found it in random months at the dollar store.

To make the chocolate orange version, add 1 to 2 tablespoons of chocolate chips, or chopped chocolate.

You could even chop up a slice of Terry’s Chocolate Orange and add that to the batter before microwaving it.

I tried making an orange chocolate version of this with cocoa powder too and I found the double chocolate overwhelmed the orange.

I think this mug cake tastes best with just the addition of the chocolate chips.

To make this a keto orange cake, use a keto-friendly sugar like monk fruit or erythritol.

You can take out the fresh orange juice if you want and add in ¼ tsp orange extract.

But since most of the orange flavor comes from the orange zest, you could just use zest and call it a day.

Follow the rest of the recipe as it is.
