The BEST Keto Chocolate Mug Cake Recipe

Pinterest Hidden Image

Mug cakes are my go-to when I feel for something sweet. They take no more than 5 minutes to whip up and can be made in a variety of flavors depending on my mood. Of course, chocolate is my favorite. This Keto Chocolate Mug Cake Recipe is in heavy rotation in my house and I bet it will be in yours too.

It’s made in the microwave with just a few ingredients, some which can be subtracted if you don’t have them on hand. Because I try to limit sweeteners, flours and too much heavy cream when I’m deep in keto to try and move the scale, I tend to not have desserts and snacks at the ready in my house. These ingredients, though keto, can actually lead to a stall in your progress and if overdone can even lead to you gaining weight while in ketosis.

They’re fine when you’re in keto maintenance mode and need to add in fat to your diet, but always remember that if you’re doing the ket diet to lose weight, there’s no need to meet your fat macro. Allow your body to burn the fat you’re already carrying around instead of the excess fat you’re eating. You only need enough fat that will make you feel full.

I tend to make mug cakes when I’m intermittent fasting and have only eaten one meal for the day. A mug cake at the end of my eating window tends to round out my calories and gives me enough fat to keep me satiated so I won’t feel hungry and want to snack before bed.

If you’re lost and unsure how to start the keto diet, this meal plan is for you. It’s a foolproof guide to winning at the high-fat, low-carb lifestyle. Enter your details below and start now!

How to Make a Delicious Keto Chocolate Mug Cake

To make this mug cake, you will need the following ingredients:

The butter and heavy cream are crucial in this recipe to make your cake moist and delicious. You can use any keto sweetener you like, my preference in taste is the monk fruit sweetener.

You can use this recipe as your base for any keto mug cake, simply swap out the cocoa powder for almond flour or use 2 tbsp straight coconut flour instead. Then, you’ll want to add in your flavoring. I’ve used banana flavoring for a banana cake, I’ve used this Birthday cake flavored protein powder for a delicious tasting plain cake and I’ve simply added in cinnamon for a wonderful plain cake.

You can also swap the cocoa powder for your favorite protein powder for a protein-packed mug cake! Way to switch up the flavors and have a different cake every time. Feel free to use my code below to get yourself a protein powder that’s sugar-free with clean ingredients for the keto diet and bar of keto sugar-free chocolate. Put a square into the middle of this dough for a wonderful molten lava mug cake!

I’ve served it here with fresh strawberries but this will also be delicious topped with the cream cheese filling from my Red Velvet Keto Waffle Whoopie Pie.

This recipe as is comes out at 6.1g net carbs. This is why I usually wait till the end of the day to have these, so I know what my carb count for the day is like. When I’m eating only one meal a day, I’m usually also doing a carnivore meal and can totally afford the 6 carbs.
