Health notes
- Chocolate protein powder: Half the flour and all of the boost — it bakes into the crumb.
- Greek yogurt: The anti-dryness insurance. Protein powder drinks moisture as it bakes; the yogurt gives it back.
- Dutch cocoa and espresso powder: Deep, dark chocolate flavour — the espresso makes the chocolate taste more like itself, not like coffee.
- Sugar-free chocolate chips: The second chocolate hit, in the batter and glossed on top.
- Locked from the cover: The photo supplied the title, claims, time and macros, so they are kept consistent throughout the block.
Key element — pull it early, gloss it hot
Protein powder keeps drinking moisture after the loaf leaves the oven, so a loaf baked to a clean toothpick turns dry by morning. Pull it when the tester still shows moist, fudgy crumbs — then scatter the remaining chips over the hot top, wait 2 minutes, and spread them into the glossy coat you see in the photo. The residual heat does the melting; the loaf does the rest as it cools.
Ingredients
Dry
- 1½ cups almond flour
- ½ cup chocolate protein powder (about 2 scoops)
- ⅓ cup Dutch cocoa powder
- ⅔ cup erythritol or monk fruit sweetener
- 1½ tsp baking powder
- 1 tsp espresso powder (optional, deepens the chocolate)
- ¼ tsp salt
Wet
- 3 large eggs
- ¾ cup plain Greek yogurt (0% or 2%)
- ¼ cup melted butter or coconut oil
- ¼ cup milk or unsweetened almond milk
- 2 tsp vanilla extract
Double chocolate finish
- ¾ cup sugar-free chocolate chips, divided — ½ cup folded in, ¼ cup for the top
Swaps
- Vanilla protein powder: Works fine — add 1 extra tablespoon of cocoa.
- Mocha loaf: Strong cold coffee instead of the milk.
- Orange chocolate: Orange zest and a drop of orange extract in the batter.
- Nutty: Toasted chopped pecans or walnuts folded in with the chips.
Instructions
| 1 | Heat and line. Heat the oven to 350°F. Line a 9×5-inch loaf pan with parchment, leaving an overhang sling — exactly like the liners in the photo. |
| 2 | Whisk the dry. Whisk the almond flour, protein powder, cocoa, sweetener, baking powder, espresso powder and salt until no cocoa lumps remain. |
| 3 | Whisk the wet. In a second bowl, whisk the eggs, yogurt, melted butter, milk and vanilla until smooth and glossy. |
| 4 | Combine and fold. Stir the wet into the dry until just combined — the batter will be thick. Fold in ½ cup of the chocolate chips. |
| 5 | Bake to fudgy crumbs. Scrape into the pan and smooth the top. Bake for 33–35 minutes until the top is set and a tester comes out with moist crumbs — not clean, not wet batter. |
| 6 | Gloss and cool. Scatter the remaining ¼ cup of chips over the hot loaf, wait 2 minutes, then spread them into a glossy coat. Cool in the pan for 15 minutes, lift out by the sling and cool fully before slicing into 10. |
Pro tips
- Moist crumbs on the tester is the target — a clean tester means a dry loaf tomorrow.
- Room-temperature eggs and yogurt mix smoother and rise better.
- Sift the cocoa if it is lumpy; bitter pockets ruin a bite.
- Slice with a hot, dry knife for the cleanest cuts.
- Day two is peak loaf: the crumb settles fudgier overnight.
