Wendy’s Keto Chocolate Frosty Copycat


There is nothing better than a cool, creamy, and sweet Wendy’s chocolate Frosty! These used to be my absolute weakness!

It’s not quite ice cream, and it’s not quite a shake… it’s a Frosty! The only problem? Well, not only is it delicious, but it is unfortunately loaded with sugar! That’s obviously a no-go if you’re trying to live a ketogenic lifestyle, but don’t worry!

This keto Chocolate Frosty Copycat tastes so much like the real thing! Satisfying your craving for smooth, rich, chocolateyness is easy with this keto chocolate frosty copycat.

This keto frosty copycat is the perfect treat to keep you cool this summer. The refreshing coolness mixed with the light and airy frozen chocolate will help you conquer even the hottest of summer days.

If that wasn’t cool enough, we made this delicious copycat using only four ingredients! That means that you can probably go to your kitchen right now and find all of the ingredients you need to make this awesome keto chocolate Frosty!

Even though this keto frosty copycat is excellent for summer, there really is never a bad time for keto ice cream! Summer, Winter, Spring, or Fall, hot or cold, this keto chocolate frosty makes for a great treat!

There are some really great keto friendly ice creams out there that can probably be found at your local grocery store, but if you prefer to eat simply (i.e. foods with simple ingredients) then you will love this keto frosty copycat.

How To Make Keto Chocolate Frosty

  1. Gather heavy cream, unsweetened cocoa powder, Lakanto powdered sweetener, and vanilla extract.

2. Combine all ingredients in a large bowl.

3. Blend until stiff peaks form; freeze for at least 30 minutes.

4. In order to get the right consistency, you will need to either stir the mixture with a spoon, or use a blender to soften the Frosty and give it that not-completely-frozen/not-too-melty consistency. Serve in a mug, bowl, or glass and enjoy!

Using Lakanto’s Monkfruit To Sweeten

We used Lakanto’s Powdered Monkfruit for this recipe and it turned out great!

Honestly, though, we use Monkfruit in some form or another for just about everything we make and it always turns out great!

Monkfruit is delicious alternative sweetener that is completely natural, is zero glycemic, and of course tastes great! It works perfectly in pretty much any sweet recipe, and this keto Frosty copycat is no exception.

Lakanto’s Powdered Monkfruit sweetener is the best substitute for powdered sugar! We also used it to make our Keto Pecan Snowball Cookies!
