• 1/4 cup (30 g) vanilla protein powder
• 2 tbsp (16 g) oat flour
• 1/4 tsp baking powder
• 1/4 tsp ground cinnamon
• 1 tbsp (12 g) granulated sweetener (e.g., erythritol or sugar)
• Pinch of salt
• 3 tbsp (45 ml) milk (dairy or plant-based)
• 1 large egg white
• 1/2 tsp vanilla extract
• Cinnamon Swirl
• 1/2 tbsp (7 g) melted butter or coconut oil
• 1 tbsp (12 g) brown sugar or coconut sugar
• 1/2 tsp ground cinnamon
• Cream Cheese Topping
• 1 1/2 tbsp (20 g) light cream cheese, softened
• 1 tsp milk
• 1/2 tbsp (6 g) powdered sweetener or sugar
• 1/4 tsp vanilla extract

Instructions

Step 1

In a microwave-safe mug (at least 10 oz/300 ml), combine the protein powder, oat flour, baking powder, cinnamon, sweetener, and salt. Mix well.

Step 2

Add milk, egg white, and vanilla extract to the dry ingredients. Stir until a smooth batter forms.

Step 3

In a small bowl, mix melted butter, brown sugar, and cinnamon for the swirl.

Step 4

Drop spoonfuls of the cinnamon swirl mixture onto the cake batter and use a toothpick or knife to gently swirl through the batter.

Step 5

Microwave on high for 60–90 seconds, until the cake is just set (center should look cooked but still moist; do not overcook).

Step 6

While the cake cools slightly, beat together the cream cheese, milk, powdered sweetener, and vanilla until smooth.

Step 7

Spread the cream cheese topping over the warm mug cake and enjoy immediately.

Zusatztipps für die Zubereitung

Adjust sweetness to taste and swap in your favorite protein powder flavor to customize the cake. Be sure to use a mug that is at least 10 oz (300 ml) to prevent the batter from overflowing during the microwave process.

Varianten und Anpassungen

For a gluten-free version, you can substitute the oat flour with almond flour. If you prefer a tangier topping or want to save a few calories, use Greek yogurt instead of cream cheese.

Cooking Questions & Answers

→ Can I make this gluten-free?

Yes, simply substitute the oat flour with almond flour and ensure your protein powder is certified gluten-free.

→ What protein powder works best?

Vanilla whey or casein protein powder yields the best texture, but plant-based options like pea or soy protein also work well.

→ Why did my mug cake turn out rubbery?

Overcooking is the most common cause. Microwave for 60-90 seconds maximum—the center should look moist but set when done.

→ Can I use a regular egg instead of egg white?

Yes, but the texture will be slightly denser. Using just the white keeps it lighter while still providing structure.

→ How do I store leftovers?

This is best enjoyed immediately while warm. If storing, refrigerate for up to 2 days and reheat for 15-20 seconds before serving.

→ Can I bake this instead of microwaving?

Bake at 350°F (175°C) for 12-15 minutes in a ramekin, though the texture will be more like traditional cake than the microwave version.
