These keto chocolate cupcakes have become my go-to for two reasons — firstly, they are ridiculously simple — you just chuck the cupcake ingredients in a blender and you’re done, and the frosting comes together quickly over a little heat. And secondly, that frosting is deliciously decadent.

I first made these low-carb cupcakes during first trimester pregnancy cravings and may or may not have eaten nearly the entire mix before it even made it to the cupcakes!

A few heads up — these gluten-free cupcakes are super easy and richly chocolatey, however due to the method of using a blender, they are a little denser than regular cupcakes. They also, surprisingly, don’t taste great warm, so you’ll need to exercise a little patience before sampling, but trust me — you want to wait until they’re slathered in some of that delicious keto-friendly frosting before your try one out!

I used a bakers chocolate bar for the frosting because that’s all I had on hand and it was incredible. This is the first baking recipe I’ve tried that actually tastes like what I had hoped for and it was so easy. Thank you! I had missed chocolate and this hit the spot!


Thank you Casey, I'm glad you enjoyed!


Why use a chocolate bar when dry cocoa plus butter or coconut oil can be used? Who keeps sugar-free chocolate bars at home?


Sugar-free chocolate bars are an option that was just suggested - we actually used 90% dark chocolate bar which is not difficult to find. You can use your favourite frosting - there isn't just one way to make it. You could even use an avocado: Keto Chocolate Cupcakes with Avocado Buttercream


Hi NJ! Dark chocolate is not the same as dry cocoa (or cacao) + butter/coconut oil, and therefore results in a different end product. Using dark chocolate will create a more ganache-like frosting whereas cocoa and butter will create a more traditional buttercream frosting. Either would be delicious but using the melted chocolate is creates a lovely decadent ganache which really makes these cupcakes special 😊
Thanks, Dearna
