How to Make It (In Just Minutes)
The process is incredibly simple. I start by whisking the egg, melted butter, oil, and almond extract right in the mug. This ensures the fats are well-emulsified for a better crumb.
Next, I stir in the almond flour, sweetener, espresso powder, and spices. The key here is to mix vigorously until smooth—no dry pockets allowed. I let it sit for about 30 seconds; this brief pause lets the almond flour hydrate, which is my secret for a non-dry cake.
Microwave on high for about 80 to 90 seconds. Watch it puff up—it’s quite the show! Let it cool for a minute or two so the structure sets before digging in.
Laura’s Tips for Mug Cake Success
- Don't Overcook: Microwaves vary wildly. Start with 80 seconds. The top should be springy, not wet, but if you overdo it, it can become dry.
- The Mug Matters: Use a wide mug (at least 12 ounces). A wider surface area helps the cake cook evenly without overflowing.
- Customize Your Topping: I love adding a dollop of cream cheese or a splash of heavy cream while it's still warm. It creates a rich, creamy sauce that seeps into the cake.
For those interested in exploring more beverage pairings, a refreshing superfood smoothie makes a great contrast to this warm cake, offering a balanced start to the day.
