Rich, chocolatey fudge from just two real ingredients — peanut butter and dark chocolate. No oven, no ice cream maker, and no protein powder. Each piece carries 8g of protein, which makes this one of the easiest high protein snacks you can keep in the fridge. Melt, pour, chill, cut — that’s the whole recipe.

Why You’ll Love This Recipe

Most protein snacks ask you to accept a scoop of protein powder you can taste, or a long list of ingredients you don’t have. This no bake protein fudge is the opposite — just peanut butter and dark chocolate, melted together and set in the fridge. That’s genuinely the entire recipe. No oven, no baking, no powder, and no special equipment.

The peanut butter does the heavy lifting on protein, and using a crunchy variety leaves little peanut pieces running through every square. At 8g of protein per piece, it sits somewhere between a treat and a snack — rich enough to feel like dessert, filling enough to actually satisfy. If you already love no bake protein bars and quick no bake recipes, this fudge is the fastest one in the collection.

Ingredients You’ll Need

(Full measurements in the recipe card below)

• Peanut butter — the protein source and the base of the fudge. Natural, unsweetened peanut butter works best. I use crunchy so you get little peanut pieces through every square, but smooth works too for a cleaner texture.
• Dark chocolate — melts into the peanut butter to set the fudge firm. A good couverture or dark chocolate chips both work. The higher the cocoa percentage, the less sugar and the more intense the flavour.
