Prep your base: Add Greek yogurt (or silken tofu) to a blender or mixing bowl.
If using tofu, pat dry and crumble first for easier blending.
Add the dry ingredients: Tip in protein powder, cocoa powder, sweetener, and a pinch of salt. Sift cocoa if it’s clumpy.
Add the flavor: Spoon in hazelnut butter and pour in vanilla extract. This is where the Nutella-like taste comes from.
Adjust thickness: Start with 1/2 cup milk.
Blend or whisk until smooth and glossy. Add more milk a tablespoon at a time until it looks like thick pudding.
Optional stabilizer: If you like a firmer set, bloom gelatin in warm water until dissolved, then blend it in. Or stir in chia seeds and rest for 10 minutes to thicken.
Taste test: Adjust sweetness and salt.
Cocoa can mute sweetness, so add a bit more sweetener if needed.
Chill: Spoon into small ramekins or glasses. Chill at least 30–60 minutes. With gelatin or chia, give it 1–2 hours for the best set.
Finish and serve: Top with a sprinkle of chopped toasted hazelnuts or a few cocoa nibs.
Serve cold.
