This lemon keto bomb recipe is such a refreshing, fun treat. I love how easy they are to make. If recipes are too complicated, then I typically don’t make them. These no-bake Lemon Fat Bombs only require four ingredients and can be ready for the freezer in about 10 minutes without heating the kitchen.

This recipe is much like my Strawberry Fat Bombs but tweaked just a bit to add lemon to have an entirely different flavor. Even if you don’t love to cook or aren’t experienced making fat bombs, anyone can make these. Since fat is the most significant part of a Ketogenic Diet, having Fat Bombs on hand when hunger or cravings hit can keep you on track.

I don’t love a lot of extra tools in my kitchen, as I like to keep it simple, but I have found that a zester and citrus juicer comes in handy.


Be careful when using a zester, as you only want to use the very top layer of the lemon zest. If you go any deeper, you will be getting the bitter part of the lemon peel.

I recently added a citrus squeezer to my kitchen tools for my Lemon Pie and Key Lime Mousse recipes. I can’t believe how much more juice it gets out and how easy it is to use.


  •   Whipping Cream– High fat and low carb, heavy whipping cream is the perfect base for your fat bombs.
  •   Zested Lemon Peel– Used to add additional lemon flavor. If you do not have a zester, see below for tips and other zesting methods.
  •   Lemon Juice– When making these fat bombs, I use freshly squeezed lemon juice. To get 3 tbsp of lemon juice, you will need to juice about half a lemon.
  •   Swerve Confectioners– A carb-conscience sugar alternative. Swerve Confectioners sugar is a must for your keto desserts. See below for other sugar alternatives.

Usually made with a high-fat base such as cream cheese, heavy cream, coconut oil, or nut butter, keto bombs are high-fat, low carb, sugar-free, bite-sized treats. These keto desserts are a great snacking option for anyone on a keto diet (or anyone who isn’t), curbing sugar cravings and providing energy. Keto bombs can be made in a variety of ways, and flavors can be customized to fit an individual’s preference. See below for more of my delicious keto bomb recipes


Adding lemon zest is a great way to add a burst of flavor to your lemon fat bombs and other keto desserts. Zest of one medium-sized lemon equals around one tablespoon of zest. 

I used a citrus zester; however, if you don’t have one, don’t worry; there are other techniques to use. 

Option 1, a cheese grater: When using a cheese grater, make sure you use the side with the small holes to get the thinly grated zest. 

Option 2, a knife: Carefully cut the yellow peel off the lemon, avoiding the white pith as much as possible. Once the peel has been removed, chop it into fine pieces.


When I make this lemon keto bomb recipe, I like to use swerve confectioners sugar. Swerve is a natural, calorie-free sweetener that doesn’t raise blood sugar. The best part, it measures like sugar, so using it as a sugar substitute is easy! If you don’t have to swerve confectioners sugar, try using Powdered Monk fruit Sweetener. Similar to Swerve confectioners sugar, powdered monk fruit sweetener has zero carbs and zero calories. This keto-friendly sugar alternative also substitutes with sugar 1:1. 

Tip: When making desserts, I do not recommend using stevia as a sweetener, as it tends to taste bitter in baked goods.
