How I came up with this 5-ingredient keto frosting recipe

This is one of the few recipes which hasn’t been hanging on my to-do list for very long. Actually, just a couple of weeks ago, I suddenly got an idea about strawberry daiquiri frosting. I think I got the idea simultaneously with the idea of this keto dessert with strawberries and rhubarb.

To be honest, I didn’t even remember what ingredient strawberry daiquiri (the drink) uses, but I had a vague memory that in addition to strawberry, it included some lime. And the classic strawberry daiquiri certainly contained alcohol, but I couldn’t recall which alcohol it was, so I had to search for a strawberry daiquiri drink recipe on the web.

Soon, I found out that the alcohol in daiquiri is rum. Well, that was easy to replace with rum flavoring! I haven’t been too keen on alcohol for a long time, so rum flavoring sounded like a great alternative to lend the necessary characteristic flavor of rum which is an essential part of the strawberry daiquiri experience. Vodka, for example, would have been more difficult to replace.

I knew I wanted to use butter and powdered erythritol as a base for my frosting. After some pondering, I took some leftover strawberries from the freezer, defrosted them, and pureed into a smooth puree. I was planning to add the puree to the fluffy mixture of butter and sweetener.

For the lime taste, I chose freshly-squeezed lime juice, and lastly, I needed the rum flavoring to complete the recipe.

Next, I pondered over the measures. I decided to make a smaller batch first. If my frosting was a failure — let’s say, it would separate after adding the strawberry puree and the lime juice — I wouldn’t need to throw that much stuff away. Butter is a delicate ingredient and upsets (i.e., separates) easily if not treated right.

I combined 4 oz (115 g) unsalted softened butter and 1/2 cup (120 ml) powdered erythritol and beat them until fluffy. Next, I added 2 tablespoons of pureed strawberries, 1 tablespoon of lime juice, and 1/2 teaspoon of rum flavoring.

I used a deep and narrow bowl like I always do for my frostings because it makes the fluffiest frosting, and you don’t need to beat the ingredients that long time like when using a shallower bowl.

After adding the ingredients and giving the mixture a short beat, the frosting looked wonderful! It had a pretty salmon-red hue, and the taste was simply divine! The strawberry gave the frosting a wonderful and brisk fruity flavor, the butter made the frosting rich, the lime juice balanced the richness of the butter, and the rum flavoring lent an extremely decadent flavor — and completely without alcohol. Awesome! I immediately fell in love with this celestial frosting that looked so beautiful, too!

Well, there could have been a tad more rum flavoring, but otherwise, I was very happy with the recipe and how it turned out. I decided to double the recipe for this post — and also double the amount of rum flavoring.

As I said, this frosting immediately became one of my all-time favorite keto frostings!

Tips for variations

This frosting is perfect as is, however, feel free to use any natural keto-friendly sweetener you like, powdered erythritol is not a must. Well, the sweetener should dissolve easily in the frosting, so I don’t recommend a granular sweetener. Powdered and liquid sweeteners work best.

Talking about sweeteners: you can certainly replace part of the erythritol with another — flavored — sweetener to amp up the flavors, like lemon-flavored stevia, or these exciting strawberry and kiwi flavored water drops.

Nothing prevents you from converting other classic drinks into creamy frostings. How about Mojito, Margarita, or Cosmopolitan buttercream frosting?

However, if you are not a fan of rum flavor or any alcohol flavor, you can omit the rum or rum flavoring altogether.

General prattling

This week went with Ketokamu activities and working on the Chichewa language. I was also speaking at the Biohacker Summit in Helsinki on Friday.

My talk was about clean keto.

I was also presenting our Ketokamu products to an international audience. The atmosphere was amazing, people were kind and friendly, and almost everybody was smiling. Those people were truly interested in maximizing their health and wellbeing.

On Saturday, I was in another event here in Tampere, again presenting and selling our Ketokamu products and my books.
