Caution - Allergen & Dietary Alerts
Please read before making, especially if preparing for others.
- Contains coconut: Made with coconut flour. Why: coconut is classed as a tree nut by some authorities; this recipe relies on coconut flour, so there is no coconut-free version as written.
- Plant milk may add allergens: Depending on the milk you choose (almond, soy, oat). Why: pick one that matches your dietary needs.
- Naturally gluten-free if your protein powder is certified gluten-free. Why: coconut flour is gluten-free, but check the protein powder label.
- Vegan, dairy-free, and egg-free as written (egg replaced with flax, maple syrup instead of honey).
Always check individual product labels, as ingredients and "may contain" warnings vary by brand.

About This Recipe
There is a particular kind of evening that calls for something warm and a little sweet, but not a whole baking project. This mug cake is the answer: one mug, a few pantry staples, and about five minutes from craving to spoon. It is soft, gently vanilla-scented, and quietly high in protein, so it satisfies without the sugar crash.
Because it is fully plant-based, the egg is replaced with a flax egg, which keeps the crumb tender while adding fiber. Coconut flour gives it structure with just a tablespoon, and a little maple syrup brings the sweetness. The result feels like a treat, but one that works with your goals rather than against them.
It is also a smart, single-serving way to get protein in. A scoop of Hanuvier's Plant Protein & Collagen Booster, which combines plant protein with collagen-supporting nutrients in a single daily serving, is the base of the batter.
At a Glance
Prep Time: 4 minutes
Cook Time: 1 to 2 minutes
Total Time: About 5 minutes
Servings: 1
Difficulty: Easy
Dietary Tags: Vegan, Dairy-Free, Egg-Free, Gluten-Free (check labels), Contains Coconut
Ingredients
- 1 scoop Hanuvier Plant Protein & Collagen Booster
- 1 tbsp coconut flour
- 1/4 tsp baking powder
- 1 flax egg (1 tbsp ground flaxseed + 2.5 tbsp water, rested 5 minutes)
- 4 to 5 tbsp plant-based milk
- 1 tbsp maple syrup
Instructions
- Make the flax egg: stir the ground flaxseed and water together and let sit for 5 minutes until gel-like.
- In a large, microwave-safe mug, mix the Hanuvier Plant Protein & Collagen Booster, coconut flour, and baking powder.
- Add the flax egg, plant-based milk, and maple syrup, and stir until you have a smooth, thick batter. Add a splash more milk if it looks dry, as coconut flour is very absorbent.
- Microwave on high for 60 to 90 seconds, until set in the center.
- Let it cool for a minute, then enjoy straight from the mug, with berries or a drizzle of maple syrup if you like.
Chef's Tips
- Mind the coconut flour. It is very absorbent, so add enough milk to keep the batter moist - dry batter bakes into a dense cake.
- Do not overcook. Start at 60 seconds; microwaves vary, and an extra 30 seconds can dry it out. Stop when the center is just set.
- Use a large mug. The cake rises as it cooks, so give it room.
- Add-ins. Fold in a few berries, a square of dark chocolate, or a spoon of nut butter before microwaving.
- Let the flax egg set. The full 5 minutes helps it bind the cake properly.

Wellness Connection
A protein-forward mug cake is a small example of working with your cravings instead of against them. The protein and fiber make it genuinely satisfying, the maple keeps the sweetness gentle, and it all comes together without anything processed. Choosing a treat like this when you want something warm and sweet is the kind of small, repeatable decision that supports the body as a connected whole - exactly how Hanuvier thinks about wellness.
Frequently Asked Questions
Why is there no egg?
This is a fully plant-based recipe, so the egg is replaced with a flax egg (ground flaxseed and water), which binds the cake while adding fiber.
Can I use regular flour instead of coconut flour?
Coconut flour is very absorbent and used in a small amount; if you swap in a flour like oat or all-purpose, you will need more of it (about 3 tablespoons) and a little more milk. Note that all-purpose flour is not gluten-free.
It came out dry - what happened?
Usually too little milk or too long in the microwave. Keep the batter moist and start at 60 seconds, adding time only as needed.
Can I bake it in the oven instead?
Yes. Pour into a small oven-safe ramekin and bake at 350 F (175 C) for about 12 to 15 minutes, until set in the center.
What is Hanuvier's systems-based approach to wellness and beauty?
The body functions as an interconnected system, with nutrients participating in multiple biological processes and often working alongside one another. Hanuvier uses this systems perspective to develop thoughtfully formulated products that support wellness, beauty, or both through a holistic approach rather than a single-ingredient focus.
