Plus, making low carb chocolate mug cake is incredibly easy. Here, I’ll tell you all about it…

What Is Keto Mug Cake?

If you haven’t tried a low carb chocolate mug cake yet, you’re in for a treat. It’s moist and chocolate-y, and tastes like a real dessert. And the best part? This easy keto mug cake is ready in just a few minutes!

Keto chocolate cake in a mug is exactly what it sounds like… it’s a single-serve chocolate cake that’s made in a mug! Easy, fast, and made with common ingredients for anyone that likes gluten-free, paleo, or low carb cooking. All you need is salted butter, unsweetened baking chocolate, almond flour (make sure it’s blanched and finely ground!), sweetener, baking powder, egg, and vanilla extract (optional).

How To Make A Keto Mug Cake In The Microwave

The original recipe for how to make chocolate mug cake uses the microwave, making it ultra fast to prepare. If you prefer the oven, no problem! We’ll cover both ways, so you can decide what is best for you.

• Melt the butter and chocolate. You can make your paleo chocolate cake in a mug or in a ramekin, and melt the butter and chocolate right in there.
• Mix up the batter. Stir in almond flour, sweetener, baking powder, egg, and vanilla into the ramekin or mug.
• Cook. Microwave the mug cake for 60-75 seconds, until just firm.

TIP: This last step is really the only “trick” to the recipe. As long as you don’t overcook your low carb chocolate mug cake, it won’t be dry! You want it to be spring-y, but not dry.

How To Make A Keto Mug Cake In The Oven

You can also bake this paleo mug cake chocolate in the oven too.

• Preheat the oven to 350 degrees F.
• Melt the butter and chocolate. Melt the butter and chocolate together in a double boiler.
• Mix up the batter. Stir in the almond flour, sweetener, baking powder, egg, and vanilla.
• Bake mug cakes. Transfer batter into ramekins and bake for about 15 minutes.

TIP: You’ll need either a large 12-oz ramekin or two small 6-oz ramekins. Make sure your ramekins are a lot bigger than the volume of the batter (about double the size), because the cake will rise as it’s baking.

Paleo Chocolate Mug Cake Ingredients & Substitutions

There are also some substitution alternatives, depending on your needs.

Keto Mug Cake Without Milk:

Unlike many other chocolate mug cake recipes, this one has no milk. Don’t worry – it’s not dry at all! The butter and chocolate in there keep it ultra moist.

In fact, it’s probably the moistest chocolate mug cake I’ve ever had. (And I’ve made plenty of them.)

Dairy-Free Keto Mug Cake:

If you need the keto chocolate mug cake to be completely dairy-free, you can also replace the butter with ghee or coconut oil. When you substitute one of these, just add a pinch of salt to compensate for the salted butter.

Personally, I prefer grass-fed butter for the best flavor, if that works for you. Many people include it in a paleo diet, as well.

Low Carb Mug Cake Sweetener Options:

Regarding the sweetener, any granulated one will work for this easy chocolate mug cake recipe. I like erythritol or allulose but some paleo followers may prefer coconut sugar instead. Up to you!

Toppings For Paleo Chocolate Cake In A Mug

It’s delicious on its own, but my favorite way to enjoy this delicious mug cake is to add toppings. For the ultimate keto mug cake, top it with

• More (sugar-free) melted chocolate
• Chopped nuts
• Homemade whipped cream – you don’t even need sweetener, but can add some powdered sweetener if you like
• Sugar-free keto ice cream – my favorite topping!
• Peanut butter drizzle

How To Store Low Carb Chocolate Mug Cake

If you find yourself with some extra low carb flourless chocolate mug cake (I don’t know how this would happen!), you can store it at room temperature for a day, or in the fridge for 2-3 days.

This keto mug cake recipe is best fresh, but you can store it for a few days.

Can You Store Paleo Chocolate Cake In A Mug?

Yes, you can store these paleo mug cakes right in the mug if you’d like. Seal the top tightly with plastic wrap to avoid drying out.

Can You Freeze Paleo Chocolate Mug Cake?

Yes, you can freeze paleo chocolate mug cake. Wrap tightly in plastic wrap and store in the freezer. Let it thaw in the fridge and then re-heat in the microwave or oven until just warm.

TIP: You can add a bit of butter or ghee on top before reheating to keep the mug cake moist.

2. Add the almond flour, sweetener, baking powder, egg, and vanilla (if using). Stir everything well until completely mixed together.

Oven Instructions

1. Preheat the oven to 350 degrees F (177 degrees C).

2. Melt the butter and chocolate together in a double boiler on the stove. Be careful not to burn it. Remove from heat.

3. Add the almond flour, sweetener, baking powder, egg, and vanilla (if using). Stir everything well until completely mixed together.

4. Transfer the batter to a large 12 oz (355 mL) oven-safe ramekin (or two smaller 6 oz (178 mL) ones). Make sure the ramekins are at least double the volume of the ingredients, because the cake will rise. Bake for about 15 minutes, until just firm.

5. Serve with whipped cream (or coconut whipped cream for paleo), and/or drizzle with more melted chocolate stirred with sweetener.
