This is the ultimate “emergency” winter comfort—a single-serving, delicate treat that takes less than 5 minutes. Combining the creamy protein of cottage cheese with the bright, seasonal pop of tangerines creates a snack that is both luxurious and refreshing.

Because we aren’t using yeast, the “good mood” comes from the steam created by the cottage cheese, which makes the cake feel like a warm, set custard or a miniature souffle.

The 4-Ingredient “Instant Mood” Mug Cake

• Cottage Cheese: (3-4 tbsp) Use a fine-curd or creamy version for that delicate texture.
• Egg: (1 large) This provides the lift and the “wrap” for the fruit.
• Tangerines: (1-2) Peeled and separated into segments (or sliced into tiny “rings”).
• Oat Flour or Semolina: (2 tbsp) Just enough to bind the moisture.

Easy Preparation (3 Minutes)

1. The Mix: In a large mug, whisk the egg and cottage cheese together until smooth. Stir in your flour/semolina and a pinch of sugar (or honey) if you like it sweeter.
2. The Fruit Center: Push half of your tangerine segments into the middle of the batter.
3. The Bake: Microwave on high for 90 seconds to 2 minutes. It will puff up significantly (like a meter-long cake in miniature!) and then settle slightly.
4. The Garnish: Top with the remaining fresh tangerine segments.

Why this is a Winter “Must-Have”

• Delicate Texture: The cottage cheese keeps the sponge incredibly moist, preventing that “rubbery” texture some mug cakes have.
• The Tangerine Pop: Unlike apples which become jammy, tangerines stay juicy and provide a “burst” of flavor against the creamy dough.
• Luxurious Finish: If you want to lean into that “nut and cream” theme, top the finished mug cake with a spoonful of Greek yogurt and a sprinkle of crushed walnuts.

A Little “Pro” Tip

If you want it to feel more like a Linz cake, add a tiny pinch of cinnamon or ground cloves to the batter. The smell of tangerines and cloves is the quintessential “instant good mood” scent of winter.
