Keto Tie-Dye Cake

It really doesn’t get more fun than this colorful keto tie-dye cake! The rainbow of colors makes it instantly festive and an eye-catching party treat!

Did I mention there are only 5g net carbs per serving??

Now that is cause for celebration!

One of the most common concerns I hear about a keto diet is about desserts. I get it, I have a sweet tooth too, but you don’t have to give up desserts to live a keto lifestyle! This Keto Tie-Dye Cake is one of the best examples of a fun and delicious dessert that anyone can enjoy. 

Why Use a Slow Cooker?

Two words: it’s easy!

Slow cookers are known for allowing you to “set it and forget it” when cooking. This also applies to cake baking!

When you bake a cake in the crockpot, it’s pretty much foolproof. With the lid, it steams the cake to create a perfectly moist texture that is hard to achieve in a conventional oven.

Plus, in a practical sense, slow cookers are more energy efficient and don’t heat up the whole kitchen like an oven does!

Once you try a slow cooker cake recipe, you might never go back!

Oh, and of course, this one is keto-friendly, so that’s another big bonus! But it’s so tasty that anyone will love it!

Kitchen Tools Used

Instructions

To Prep: Coat your slow cooker bowl with non-stick spray.

In a large mixing bowl, combine all of the ingredients for the cake except the food coloring. Whisk until well blended and you have a smooth cake batter.

Divide the batter into four smaller bowls and add a few drops of food coloring to each bowl, using a different color for each bowl. Stir to transform the batter in each bowl into a bright color.

Drop the batter by the spoonful into the bottom of a well-greased Crockpot, alternating colors as you go.

Cover and cook on high for 2 hours. Turn off the slow cooker and allow the bowl to cool enough to handle, then remove the bowl from the appliance itself so the cake can cool completely.

To Frost the Cake:

Mix together the icing ingredients until smooth and creamy.

I find it easier to frost the cake after I’ve cut it into individual slices and plated them.

Frequently Asked Questions

Does this Cake Need to be Refrigerated?

Because it is frosted with cream cheese icing, any leftovers should be kept refrigerated. Transfer to an airtight container and keep in the fridge for 2-3 days. This is a dessert that actually tastes better (at least I think so!) on day 2, after it’s been refrigerated. All the flavors blend and it’s extra moist!

What Flavor is the Cake?

Though it is a rainbow of colors, this keto cake is vanilla flavored. The frosting is cream cheese flavored. 

Can You Make the Cake All One Color?

Sure! You can make as many colors, or as few colors as you like! 

This would be a fun dessert to customize for holidays, such as red and green at Christmas.
