NOT that I'm making excuses – BUT. If you don't like diet coke or don't allow it on your diet plan – please just move along to the next recipe. I don't drink coffee or tea – but I *do* drink diet coke. A girl has to get her caffeine from somewhere… 🙂

I received mixed reviews for my Diet Coke Chicken recipe that I wrote a few years ago. I *get* that some people don't like aspartame. But the recipe is a good one, and it IS low carb. So when I discovered there was such a thing as a Diet Coke cake – I just HAD to experiment! And here are some cola alternatives:

  • Zevia Cola – zero carb and sweetened with stevia – available from Amazon and Netrition
  • Celcius Sparkling Cola – 2g net carbs and sweetened with sucralose
  • Virgil's Zero Sugar Cola – zero carb and sweetened with erythritol – available from Amazon
  • Diet Cola Syrup for a Soda Stream – zero net carbs and sweetened with sucralose

I saw several recipes online that use a box of chocolate cake mix and replace the eggs with a large can of diet coke. I usually have the mini “sleek” cans at home, so I decided to make a basic chocolate cake with almond flour, then add in the diet coke and some egg whites.

How to Make a Low Carb Diet Coke Cake

To make the cake, stir together almond flour, unsweetened cocoa powder, low carb sweetener (eg Lakanto or granular Swerve), baking powder and salt. It might not seem like enough sweetener for a cake, but remember that the soda will add some sweetness. Stir in the Diet Coke. It will froth up but will soon calm down after you have combined it.Low Carb Diet Coke Cake - a sugar free and gluten free recipe

In a separate bowl, whisk two egg whites together until soft peaks form. Gently fold them into the rest of the mixture.Low Carb Diet Coke Cake - a sugar free and gluten free recipe

Spoon the cake batter into a cake tin (I used a 9″ springform pan but an 8″ would probably be better). Bake in a preheated oven for 20 minutes or until the center of the cake is cooked. Leave to cool for 5 minutes then transfer to a wire cooling rack.

To make the ganache frosting, melt some unsweetened chocolate in the microwave. Leave to cool for 5 minutes, then whisk in some heavy cream, softened unsalted butter, and low carb sweetener. Keep whisking until the mixture is smooth and fluffy.

Spoon the frosting onto the cooled cake and spread it evenly.Low Carb Diet Coke Cake - a sugar free and gluten free recipe

Could I taste the diet coke in this cake? No, I couldn't. But the cake DOES taste good, and has the added bonus then when I told my husband and son what the cake was called – they didn't want to try and left it all to me! So it depends what your goals are, LOL!

what brand of Almond flour do you recommend? I found the one I use makes things taste grainy? can coconut flour be sub?

Are you in the US? I use the bags from Costco as the almonds are ground super fine. Coconut flour definitely can not be used as a direct replacement as it is much more absorbent. You'd have to add extra eggs or other liquid to accommodate that and I haven't tested the recipe with those ingredients.

Could you use Zevia instead of Diet Coke?

Georgina

Great question! I haven't tried it, but I honestly can't see why it wouldn't work. Let me know how it turns out!

Would Diet My Dew work

Technically, I suppose - but the flavor might be odd with the chocolate

This cake is right up my alley. Can Coke Zero be used? That is what I usually buy. Thank you.
