Instructions

For each of 3 microwave-safe mugs (12 oz / 350 ml), add 1 tbsp unsalted butter. Microwave 20–30 seconds until melted; swirl to coat the sides.
Into the mug, add 1 egg, just under 3 tbsp superfine almond flour, ½ tsp baking powder, 1 tbsp granular monk-fruit sweetener, a pinch of fine sea salt, a pinch of ground nutmeg, and about ⅔ tsp vanilla extract. Whisk vigorously with a fork until smooth and aerated, about 45 seconds.
Sprinkle 1 tsp golden monk-fruit sweetener evenly over the surface, then dust with ground cinnamon to taste. Do not stir.
Microwave one mug at a time on high for 90–105 seconds, until the top is set and springs back when lightly touched; a toothpick inserted in the center should come out mostly clean. Avoid overcooking.
Carefully remove the mug. Immediately add about ⅔ tbsp softened cream cheese, about ⅓ tbsp of the remaining butter, and about ⅔ tbsp powdered monk-fruit sweetener to the center. Add a few drops of heavy cream (about ⅓ tsp) if a thinner glaze is desired. Let sit 60 seconds to soften and melt.
Swirl the melted glaze to marble the top. Serve warm. Repeat for the remaining mugs.

Notes

Storage: These mug cakes are designed for immediate consumption and do not store or reheat well.
Ingredient Swaps: For a dairy-free alternative, you can substitute the butter with a neutral coconut oil or plant-based butter and use a dairy-free cream cheese product. The heavy cream can be swapped for full-fat coconut milk.
Troubleshooting: If your cake turns out dense or rubbery, it was likely overcooked. All microwaves vary; reduce your cook time by 15-second increments on your next attempt to find the perfect timing for your appliance.

These values are approximate and may vary based on ingredients and preparation. Allergens: contains tree nuts, eggs, and dairy. Use microwave-safe mugs and handle carefully; contents become very hot. Microwave wattage varies. Cook until the top is set and a toothpick comes out mostly clean.
