Ingredients

• Cake Batter: 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, pinch of salt, 3 tbsp (45 ml) milk, 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, 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; the center should look cooked but still moist.

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

To ensure a soft texture, be careful not to overcook the cake, as protein powder can become rubbery if heated for too long. Using a mug that holds at least 300 ml provides enough space for the batter to rise safely without overflowing.

Varianten und Anpassungen

For a gluten-free version, substitute the oat flour with almond flour. If you prefer a tangier topping, you can use Greek yogurt in place of the cream cheese. You can also experiment with different protein powder flavors to customize the base taste.

Serviervorschläge

For an extra touch of indulgence, serve your mug cake with a sprinkle of chopped nuts for crunch or a light drizzle of maple syrup. It pairs perfectly with a hot cup of coffee or tea for a complete dessert experience.

Recipe FAQs

→ Can I make this without a microwave?

Yes, you can bake this in an oven-safe ramekin at 350°F (175°C) for 10-12 minutes. The texture will be slightly more traditional, but watch closely to prevent overcooking.

→ What protein powder works best?

Vanilla whey or casein protein powder yields the fluffiest texture. Plant-based proteins work but may result in a slightly denser cake. Avoid unflavored powders as they won't provide enough sweetness.

→ Can I prepare this in advance?

Mix the dry ingredients ahead and store in an airtight container. Add wet ingredients and cook when ready. The finished cake is best enjoyed immediately while warm.

→ How can I increase the protein content?

Use a protein powder with 25g+ protein per scoop, substitute milk with Greek yogurt, or add a tablespoon of protein powder to the cream cheese topping mixture.

→ Why did my cake turn out rubbery?

Overcooking is the most common cause. Microwave times vary, so start checking at 60 seconds. The center should appear set but still moist—residual heat finishes the cooking.

→ Can I make this dairy-free?

Yes, use plant-based milk, coconut oil instead of butter, and a dairy-free cream cheese alternative or coconut yogurt for the topping. The texture remains excellent.
