Ingredients
Gather the following high-quality ingredients for this delightful mug cake:

- 1 tablespoon almond flour (it adds a gentle nuttiness)
- ½ teaspoon baking powder (for that perfect rise)
- 1 tablespoon unsweetened cocoa powder (to deepen the chocolatey flavor)
- 1 tablespoon sweetener of choice (I prefer erythritol, but honey works perfectly too)
Wet Ingredients
- 1 egg (the binding agent, giving it that nice soft texture)

- 1 tablespoon hazelnut spread (for that luxurious Kinder Bueno taste)
Toppings

How to Make Kinder Bueno Protein Mug Cake (Step-by-Step)
Follow these simple instructions to create your own indulgent mug cake.
Step 1: Prep Your Mug
Start with a microwave-safe mug-aim for something sturdy that can hold up to the heat. I love my large ceramic mugs for this because they add a touch of elegance.
Step 2: Mix the Dry Ingredients
In your mug, combine the chocolate protein powder, almond flour, baking powder, cocoa powder, and sweetener. Whisk them together with a fork until well-blended, ensuring there are no clumps-this step is crucial for a smooth cake.
Step 3: Incorporate the Wet Ingredients
Crack in the egg, follow up with the almond milk (yes, you can pour it straight from the carton!), and then add the hazelnut spread. Whisk gently until you see a glossy batter forming-this is where the magic starts to happen; the aroma is intoxicating.
Step 4: Microwave Time
Pop your mug into the microwave and cook on high for about 60-90 seconds. Keep an eye on it towards the end-once it starts rising and the center has just a slight jiggle, it's done. The scent of baking chocolate will fill your kitchen, and trust me, it's heavenly.
Step 5: Finishing Touches
Allow it to cool for a minute or two, then top with crushed hazelnuts for that extra crunch. You could even swirl in an additional spoonful of hazelnut spread for decadence-because why not?
Common Mistakes to Avoid
- Avoid Overcooking: Microwaves vary; keep a close watch. Overcooking can lead to a rubbery texture.
- Don't Skip the Whisking: Not combining your dry and wet ingredients well can lead to clumps and an uneven bake.
- Use a Large Enough Mug: A small mug might overflow while cooking, creating a messy cleanup.
Tips and Tricks for Success
- For a richer flavor, try using a high-quality dark chocolate protein powder.
- Serving it warm is key; this makes it extra gooey and delightful.
- Pair it with a dollop of Greek yogurt or a scoop of protein ice cream for an indulgent dessert.
Variations
- Substitute almond milk with any milk of your choice.
- Try using different nut butters instead of hazelnut spread for varied flavors.
- Add a pinch of cinnamon for a warm spice twist.
- Mix in some dark chocolate chips for added chocolate goodness.
How to Serve
- Top with crushed hazelnuts for added crunch.
- Swirl in additional hazelnut spread for extra richness.
- Serve with a dollop of whipped cream or Greek yogurt.
- Pair with fresh berries for a fruity contrast.

Make Ahead and Storage
- Make Ahead: Prepare the dry ingredients in advance and store them in an airtight container for quick assembly.
- Storage: Any leftover mug cake can be stored in the fridge for up to 2 days.
- Reheating: Reheat gently in the microwave for about 10 seconds before enjoying.
- Freezing: Not recommended as mug cakes are best enjoyed fresh.
