Ingredients and Substitutions

Fresh lemon juice and zest gives these fat bombs their bright, citrusy flavor. You can substitute lime juice and lime zest if you prefer.

Cocoa butter adds richness and structure to these treats. If it’s not available at your local stores, cocoa butter is easy to find online. Make sure that the cocoa butter is labeled food-grade, not cosmetic or for external use only.

I used macadamia nut butter in these fat bombs this time, but almond butter works too.

How to Make Lemon Fat Bombs

Add the cocoa butter to a pot on the stove set to low heat. Cook, stirring constantly until melted, then immediately remove the pot from the heat.

Add the macadamia nut butter to the pot, then whisk until incorporated. Add the lemon zest, lemon juice, vanilla extract, pure liquid monk fruit sweetener, and salt to the pot, then whisk well.

Divide the mixture evenly into 12 portions in a muffin pan lined with paper baking cups. For easier pouring, first transfer the mixture to a pitcher or container with a spout.
