Zusatztipps für die Zubereitung

For extra flavor, add a drop of vanilla extract to the batter before mixing. Keep a close eye on the microwave during the final seconds; timing is crucial to ensure the cake remains moist rather than rubbery.

Varianten und Anpassungen

You can easily swap the oat flour for almond flour to reduce the total carbohydrate count. Additionally, feel free to adjust the amount of sweetener in both the batter and the topping to suit your personal taste preferences.

Serviervorschläge

Enhance the texture by topping your finished mug cake with a handful of chopped walnuts or pecans. A final dusting of extra ground cinnamon over the frosting adds a professional touch and a boost of warmth.

Recipe FAQs

Can I make this ahead of time?

Best enjoyed fresh while warm. The texture changes upon refrigeration, but you can reheat briefly in the microwave if needed.

What protein powder works best?

Vanilla whey or casein blends well, though plant-based options may alter texture slightly. Avoid purely isolate powders as they can create a drier result.

Can I use almond flour instead of oat flour?

Yes, almond flour works as a low-carb alternative. The texture becomes slightly denser but still delicious.

Why did my mug cake overflow?

The mug may be too small. Use at least a 12-ounce mug and check your microwave wattage—reduce cooking time if powerful.

Is this suitable for meal prep?

Dry ingredients can be pre-mixed and stored. Add wet ingredients and cook fresh for optimal texture and fluffiness.
