Ingredients
To make this delectable mug cake, you’ll need:
- 2 tablespoons all-purpose flour (or oat flour for a gluten-free option)
- 1 tablespoon unsweetened cocoa powder
- 2 tablespoons granulated sugar (or substitute with honey or maple syrup)
- ¼ teaspoon baking powder
- Pinch of salt
- 2 tablespoons cottage cheese (2% or 4% milk fat works best)
- 2 tablespoons milk (dairy or plant-based)
- ½ teaspoon vanilla extract
- 1 tablespoon vegetable oil or melted butter
- 1 tablespoon chopped pistachios, plus more for garnish
- 1 tablespoon chocolate chips (optional, but recommended for extra gooeyness)
The perfect balance of these ingredients creates a cake that’s rich without being overwhelming, sweet without being cloying, and satisfying without being heavy.
Directions
Let’s break down the simple process of creating this delicious mug cake:
- Prep your mug: Choose a microwave-safe mug that holds at least 12 ounces (350ml). Lightly spray or wipe the inside with oil to prevent sticking.
- Mix dry ingredients: In your mug, combine the flour, cocoa powder, sugar, baking powder, and salt. Stir with a fork until well mixed and no cocoa clumps remain.
- Add wet ingredients: Add the cottage cheese, milk, vanilla extract, and oil to the mug. Stir vigorously until the batter is smooth and no dry pockets remain. This will take about 30-45 seconds of mixing.
- Fold in mix-ins: Gently fold in the chopped pistachios and chocolate chips (if using), reserving a few pistachios for garnish.
- Microwave: Cook in the microwave on high power for 45-75 seconds. Start checking at 45 seconds – the cake should be set around the edges but still slightly gooey in the center. The exact time will depend on your microwave’s power.
- Rest: Let the mug cake rest for 1 minute after cooking – this allows the residual heat to finish the cooking process without overdoing it.
- Garnish: Sprinkle the reserved pistachios on top. For an extra touch of indulgence, add a small scoop of Greek yogurt, a drizzle of honey, or a few more chocolate chips while the cake is still warm.
The perfect texture should be slightly gooey in the center – like a molten lava cake – while still holding its structure. If you prefer a firmer cake, add 5-10 seconds to the cooking time, but be careful not to overcook or it will become dry.

Serving and Storage Tips
For the ultimate experience, serve this mug cake warm, just a minute or two after it comes out of the microwave. The chocolate chips will still be melty, the cake will be at its most tender, and the contrast between the warm cake and cool garnishes is divine.
Serving suggestions:
- Top with a dollop of Greek yogurt for extra protein and a tangy contrast
- Add a small scoop of vanilla ice cream for a more decadent dessert
- Drizzle with a teaspoon of warm nut butter for added richness
- Sprinkle with a pinch of sea salt to enhance the chocolate flavor
While this cake is best enjoyed fresh from the microwave, you can prepare the dry ingredients in advance and store them in a sealed container or baggie. When the craving strikes, just add the wet ingredients and cook. This makes it an excellent option for travel, office treats, or late-night studying sessions.
If you do have leftovers (though that’s rare!), cover the mug with plastic wrap and refrigerate for up to 24 hours. Reheat in the microwave for 15-20 seconds before enjoying.
Helpful Notes
- Cottage cheese texture: If you’re texture-sensitive, you can blend the cottage cheese in a small food processor or with an immersion blender before adding it to the batter.
- Protein boost: For an even higher-protein version, substitute 1 tablespoon of the flour with unflavored protein powder.
- Sweetness level: This recipe is moderately sweet. If you prefer a less sweet dessert, reduce the sugar to 1 tablespoon. For a sweeter treat, add an extra teaspoon of sugar or chocolate chips.
- Microwave timing: Microwave strength varies significantly between models. Start checking your cake at the minimum suggested time and add 5-10 second increments until you find the perfect timing for your appliance.
- Nut alternatives: If pistachios aren’t your favorite, this recipe works beautifully with chopped walnuts, pecans, or almonds. For a nut-free version, try using sunflower seeds or pumpkin seeds.
- Chocolate intensity: For a more intense chocolate flavor, use Dutch-processed cocoa powder or add ¼ teaspoon of instant espresso powder to the dry ingredients.
Getting the perfect consistency might take a try or two as you get familiar with your microwave’s power, but the experimentation is delicious!
Frequently Asked Questions
Can I make this recipe dairy-free? Yes! Substitute the cottage cheese with silken tofu or dairy-free yogurt, and use your favorite plant milk. The texture will be slightly different but still delicious.
Is there a way to make this gluten-free? Absolutely. Replace the all-purpose flour with oat flour, almond flour, or a gluten-free 1:1 baking mix. Oat flour will give you the closest texture to the original recipe.
Can I make this without a microwave? Yes, you can bake this in a ramekin in a preheated 350°F (175°C) oven for about 12-15 minutes. The texture will be less gooey and more like a traditional cake.
Can I double this recipe? This recipe can be doubled for a larger serving or to share. Use a larger mug or small bowl and increase the cooking time by about 30 seconds, checking frequently.
How do I know when the mug cake is done? The top should look set but still be slightly soft in the center when lightly pressed. A toothpick inserted into the edge should come out clean, but one inserted in the center should have a few moist crumbs.
