Lusciously Lazy Keto Chocolate Buttercream Frosting


I’ve been diving headfirst into my “embrace the good enough” philosophy lately, especially when it comes to sweets. Because, let’s be real, sweets are like the siren call I can’t resist. Surprised? If you know me, you definitely aren’t. 🍫

Now, I’m no marathon baker, and my baking endurance is, well, let’s just say “selectively short.” It’s a thing, okay?

So, in a quest for ease without sacrificing my low-carb ethos, I grabbed a couple of boxes of Duncan Hines Keto Cake mix, Sure, whipping up a low-carb cake from scratch isn’t rocket science, but sometimes, you just want the easy button. However, the pre-made frosting almost killed my vibe – the reviews were a horror show. But hey, a gal needs her chocolate frosting fix, right?

I had my heart set on a Keto Chocolate Buttercream Frosting that would make angels weep. We’ve all been there, needing that frosting fix like yesterday.

After what felt like eons of wrestling with various recipes to create my own masterpiece, I finally asked ChatGPT for a lifeline. My goal? Whip up something yummy with what I had in my kitchen, which included a treasure trove of Bake Believe Sugar Free Chocolate Chips.

The result? A triumphant success! Or at least, a pretty darn tasty topping. That’s why I’m sharing this chocolaty goodness with you. And yes, I’m even showing off my slightly crumbly, delightfully messy cake. Let’s keep it real – it’s all about the taste, and this cake nailed it.

About Keto Chocolate Buttercream Frosting

This Keto Chocolate Buttercream Frosting is a bit of a chameleon. It firms up in the fridge, almost like soft candy, but gets creamier as it warms up. Pro tip: Keeping your cake chilled overnight not only enhances the flavor of most low-carb treats but also gives this frosting a deliciously firm bite.

No cake to frost? No worries. Park this frosting in the fridge, and it transforms into something akin to fudge. And yeah, I know this from, um, extensive research. 😜

Planning a bigger cake, like a 9 x 13″ masterpiece? One batch of this frosting and two boxes of cake mix should do the trick, assuming you’re on the cake mix train. Oh, and don’t forget the parchment paper – unless you want to play ‘cake archaeologist’ later. Low-carb baking loves to cling!

But this frosting isn’t a one-trick pony. It’s versatile enough for a whole array of frosting adventures. I’m all ears to hear how you put it to use!

Equipment Suggestions


  • 1 cup Sugar-Free Chocolate Chips
  • 3/4 cup Unsalted Butter (softened)
  • 1 cup Powdered Erythritol (or any powdered sugar substitute you prefer)
  • 3 tbsp Heavy Cream (or more, for desired consistency)
  • 1 tbsp Vanilla Extract
  • 1 Pinch Salt


  • Melt the Chocolate: Gently melt the sugar-free chocolate chips in a microwave-safe bowl or over a double boiler. Stir until smooth and let it cool slightly.
  • Cream the Butter: In a mixing bowl, beat the softened butter until light and fluffy. This takes about 2-3 minutes with an electric mixer. If you're using a KitchenAid, use the beater (and not the whisk) attachment.
  • Add Sweetener: Gradually add the powdered erythritol to the butter, beating until well incorporated.
  • Combine with Chocolate: Pour the melted chocolate into the butter mixture. Beat until the mixture is thoroughly combined.
  • Add Cream and Flavoring: Mix in the vanilla extract and a pinch of salt. Gradually add heavy cream, one tablespoon at a time, until you reach your desired consistency. Beat for an additional minute to ensure everything is well blended.
  • Adjust and Serve: Taste the frosting and adjust sweetness or creaminess as needed. Once satisfied, use it to frost your low-carb treats!

Recipe Notes

  • Chill Before Using: If the frosting is too soft, chill it in the refrigerator for about 30 minutes before using.
  • Storage: You can store this frosting in the refrigerator for up to a week. Just bring it to room temperature before using.
  • Serving size: Assuming 2 cupcakes or a cake cut into 12 pieces, serving size is generous frosting for one piece. Please be aware your nutritionals may be different depending on the your specific ingredients (especially the chocolate chips).

Well, folks, this got me playing mad scientist with AI-authored recipes, and guess what? It’s actually been a blast! One of the coolest perks? You can bombard the AI with questions about the recipe without the fear of sounding silly or annoying some real-life author. Seriously, you could ask if the frosting pairs well with pickles, and the AI won’t bat an electronic eye. 😆

But, fair warning: if you’re expecting the AI to whip up a picture-perfect illustration, brace yourself for something more… abstract. Think of it as a culinary Rorschach test. The AI’s take on this Keto Chocolate Buttercream Frosting? Let’s just say it’s more ‘creative interpretation’ than ‘accurate depiction.’ But hey, it’s always good for a laugh!

So, there you have it! The world of AI in the kitchen is wild, wacky, and wonderfully weird. Embrace the odd, enjoy the journey, and remember – in the realm of AI and low-carb sweets, there’s no such thing as a wrong question or too much chocolate!
