This chocolate single serve protein cake is soft, rich, and slightly fudgy, made with simple ingredients and a scoop of collagen for an easy protein boost.
It’s the kind of dessert you make when:
- you want chocolate
- you don’t want a full cake
- and you need something quick that actually tastes good
One ramekin. One portion. No overthinking.
Why You’ll Love This
- Single serve (no leftovers)
- Chocolatey and satisfying
- Fudgy, brownie-like texture
- Made with collagen for a simple protein boost
- No flour needed
- Ready in minutes
This is not a dry protein cake.
It’s a soft, rich dessert that just happens to be balanced.
What You’ll Need
- Egg
- Collagen powder (unflavored)
- Cocoa powder
- Almond flour
- Granulated sweetener of choice
- Heavy cream
- Melted butter
- Vanilla extract
- Baking powder
- Salt
- Chocolate chips (optional)
How To Make This Chocolate Single Serve Protein Cake
You’re using the same simple method as the vanilla version — just with cocoa and a slightly higher liquid ratio.
Mix everything in one bowl until smooth, then transfer to a ramekin and bake.
- The batter should be slightly thick but still pourable
- If it looks too thick, add a splash of milk
- If too thin, a little almond flour fixes it
Baking Time (This Matters Most)
This chocolate single serve protein cake is all about timing.
- 11-12 minutes → molten center
- 12-13 minutes → soft, fudgy (best)
- 13-14 minutes → more set, still moist
At 12 minutes, the center may look underbaked – that’s normal
It continues setting after you remove it from the oven
Baking time may vary depending on the type of the oven, moisture of ingredients and ramekin used.
Add-Ins (Highly Recommended)
- chocolate chips or chunks (best option)
- raspberries (perfect contrast)
- peanut butter center
- chopped nuts
Keep it simple – this cake doesn’t need much.
Important Tips
- Collagen adds protein but not structure
- Do not add cornstarch – cocoa already dries the batter (I used cornstarch in a previous vanilla version of this cake)
- Use enough liquid (this matters more than anything)
- Do not overbake – it dries quickly
Substitutions
- Heavy cream → milk or non-dairy milk
- Butter → oil
- Sweetener → sugar-free or honey
- No collagen → still works
Serving and Storage
Best eaten warm, right after baking.
