Peanut Butter Collagen Keto Fudge

There’s something incredibly satisfying about a piece of fudge—smooth, creamy, and packed with rich flavor. But traditional fudge is often loaded with sugar, making it off-limits for a keto lifestyle. That’s why we love this Peanut Butter Collagen Fudge—it’s an easy, no-bake, nutrient-packed alternative that keeps things indulgent without the sugar crash.

This recipe combines creamy peanut butter, collagen peptides, and coconut oil to create a silky texture with just the right amount of richness. Not only does it satisfy those sweet cravings, but it also delivers a boost of healthy fats and protein to keep us energized. Plus, since it’s completely sugar-free and naturally sweetened with monk fruit or erythritol, we can enjoy it guilt-free.

Perfect for meal prep, a quick snack, or an after-dinner treat, this Peanut Butter Collagen Fudge will quickly become a staple in any keto kitchen.
