Chocolate Mug Cake Featured Image


Who would believe that you could make the most delectable chocolate cake in mere minutes. Moist and velvety and full of rich dark chocolate flavours, any of our sweeteners can be used in this recipe to suit your taste.

Perfect for anyone watching their sugar and/or carb intake. You are going to love this recipe, especially if you are a chocolate lover.

Enjoy this keto chocolate mug cake by eating straight from the mug. Be a little bit fancy and transfer it onto a plate to serve. Beware, as this cake is extremely morish. Because of how rich it is, perhaps you will be able to stop at just one serve.



Serve topped simply with freshly whipped cream for a lovely sugar free, gluten free treat, low carb treat. If you are keen for full on chocolate immersion, try serving it with the chocolate sauce recipe featured. Oh my lordy….it’s rich but absolutely divine! My favorite way to serve this is topped with fresh whipped cream and a few strawberry slices.



Having made a lot of mug cakes, one thing that I have struggled with in many recipes is the eggy taste. The issue is that you need egg in the recipe and it is difficult to divide one egg in half. My solution to this problem is a bonus for you as you get 2 cakes using the one egg. The added moisture comes from using olive oil, which you will discover is absolutely awesome in this recipe.



Try to use processed cocoa powder for the ultimate chocolate experience with this recipe for keto chocolate mug cake. Cacao powder or cocoa powder can also be used but the end result won’t be as chocolaty as it is by using Dutch processed cocoa. If you use the cacao powder you may find the chocolate flavors are a little more subtle and perhaps a little bitter. The bonus is that you get the added health benefits such as antioxidants that raw cacao offers.

Triple the chocolate flavors by serving it with the optional richer than rich chocolate sauce. It’s not necessary as the cake is fabulous on it’s own, but chocoholics will love this option!



Trying to buy low sugar dark chocolate chips can be a real challenge, so I don’t even bother looking for them now. My favorite chocolate chips to use in this recipe is Lindt dark chocolate simply cut into small chunks. Not only is it nice quality chocolate but it is also very low in sugar and doesn’t contain malitol. Maltitol is used in many of the low carb chocolate products on the market. I don’t like to use it for 3 reasons. Firstly it can impact on your blood sugar levels. Secondly it can cause havoc with your bowel and lastly, it is an inferior tasting product. The other fantastic deal with using Lindt chocolate is you can choose chocolate to suit your tastes. The price of the chocolate is also very reasonable in comparison. I like to use 85 percent wherever I can as it is lower in sugar but use what suits your taste.



Coffee enhances the flavor of chocolate. Adding some instant coffee or espresso to your batter is all that is required to bring out the richness of the chocolate flavors without imparting coffee flavors. You won’t taste the coffee at all and if you don’t want to add the coffee, simply leave it out.  If you are familiar with any of my other recipes that are chocolate based, you will notice that generally I try to add coffee wherever I can. The proof is in the tasting….so I recommend that you try it.

Servings: 2 mug cake/ ramekins


  • 35 grams Almond flour 3 Australian tablespoons
  • ½ teaspoon baking powder
  • 15 grams dutch processed cocoa/cocoa or cacao powder 1.5 Australian tablespoons
  • 2 tablespoons monk fruit sweetener or to taste
  • a pinch of salt
  • 1 egg
  • ½ teaspoon coffee dissolved in 1 tablespoon hot water optional but not really optional!
  • 40 mls Extra Virgin Olive Oil- EVOO 2 Australian tablespoons. Melted butter can be substituted.
  • 2 tablespoons choc chips or 2 squares of Lindt dark chocolate cut into chips-optional but not optional! I like to to use 85% couverture because it's lower in sugar

Optional Richer than Rich Chocolate Sauce

  • 2 tablespoons pure/heavy cream heated to just below boiling point
  • ½ teaspoon sweetener of choice or to taste
  • 20 grams dark chocolate chocolate cut in to chunks 2 squares of Lindt-I like to use 85% couverture
  • A dab/smidgen of butter


To Make Mug Cakes

  • Mix the almond flour, baking powder, Dutch cocoa/cocoa/cacao, sweetener, salt and baking powder in a small bowl until well combined. Sift if necessary to remove lumps.
  • Dissolve the coffee in the hot water. Add the coffee mixture, EVOO-oil, vanilla extract and egg to the dry ingredients and stir until really well combined. Fold through the chocolate chips if you are want them stirred through the batter. Pour into 2 mugs or 2 ramekins (that hold at least 200 ml/7 oz) and smooth out the tops. Alternatively sprinkle choc chips on top of the smoothed out batter.
  • Microwave your cakes on high for about 90 seconds or until just firm, taking care not to overcook. The cakes should still be a moist and it will continue to cook once out of the microwave. If you overcook your cake it will dry out. Allow to sit for a couple of minutes in the cup/ramekin before serving. You can tip them out of the mug/ramekin or you can serve your cakes as they are, in the mug or ramekin.
  • Serve with whipped cream or whipped coconut cream for paleo. You can also drizzle with some additional richer than rich chocolate sauce (recipe below) to lux it up a little but the cake tastes fabulous on it's own as well.


  • Preheat the oven to 350 F/180 C and bake for about 12-15 minutes, or until just firm.


  • Gently heat the cream in the microwave to just below boiling point. Remove from heat and add the sweetener, butter and the dark chocolate chips stirring until the sauce emulsifies.
  • Stir until the chocolate melts and sauce is smooth. Add additional cream to thin the sauce out if desired. Pour over your mug cake and top with a dollop of freshly whipped cream.

Recipe Notes

Your cake should still be a little moist when it comes out of the microwave. Your cake will continue to cook when out of the microwave so resist the urge to cook for longer or you could dry your cake out.

If you want to turn your cake out onto a plate, allow it to cool a little so the cake doesn't fall apart and scrape down the sides of the mug/ramekin before tipping out. My preference is to eat it from the mug as you can serve the cake when it is more moist. If this recipe is slightly under cooked it still tastes fabulous but make sure you serve it in the mug/ramekin as it might not retain its shape.

As an alternative to choc chips if using Lindt/chocolate squares, you can just push a square of chocolate into each cake just below the surface of the batter and smooth off the top before baking. Be prepared for a little fudgy chocolate heaven. You can also sprinkle some or all of the chocolate chips on top of the batter once poured into the mug or ramekin, just before cooking, instead of stirring through. Note that one Lindt square is about 10 gms/1/3 oz

For a paleo option use a psyllium egg and coconut sugar for the sweetener. Top the cake with whipped coconut cream. You can just also switch the coconut cream in the chocolate sauce for coconut cream.

You can make a psyllium "egg" by combining 1 teaspoon of psyllium with 3 tablespoons water. Stir together really well and set aside for 10-15 minutes until the mix is thick and gelatinous. Use it to replace eggs as a binder in baking at a 1:1 ratio.

Note that an Australian tablespoon measures 20 mls and this is what is used for the metric measurements. A US tablespoon measures about 15 mls. Conversions have been done for US customary measures to suit the recipe and may be in tablespoons or oz.
