Ingredients and Substitutions

Flaxseed adds a nutty, slightly earthy flavor to these treats. Make sure to use ground flaxseed, not whole flaxseed. It’s usually available at grocery stores or health food stores, or you can order it online. You can also grind whole flaxseed yourself using a spice grinder or blender if you prefer.

I like to use dark chocolate with 70%-75% cacao solids when making this fudge. That percentage tends to have the perfect sweetness level, so no additional sugar is needed in these treats.

A little salt enhances the other flavors in these treats. You can omit it if necessary.

How to Make Chocolate Flaxseed Fudge

Add the ground flaxseed and cold water to a mixing bowl, mix well, then let rest for 10 minutes.

Melt the chopped dark chocolate using your preferred method:

Stovetop: add the chopped chocolate to a small pot over low heat. Stir frequently until just melted, then immediately remove from the heat.

Microwave: add the chopped chocolate to a microwave-safe bowl. Heat in 20-second bursts, stirring between each, until melted.

Transfer the melted chocolate to the mixing bowl, add the salt, then mix until incorporated and thickened. Transfer the mixture to a 9-inch loaf pan lined with parchment paper, then spread in an even layer.
