Method
1
In a microwave-safe mug or small bowl, whisk together almond-flour, baking-powder, and salt until evenly combined.
2
Add egg, honey, vanilla-extract, lemon zest, and lemon juice. Stir vigorously with a fork until a smooth batter forms — about 30 seconds. Small lumps are fine.
3
Fold in three-quarters of the blueberry gently so they stay whole. Scatter remaining blueberries on top.
4
Microwave on high power for 1 minute 30 seconds. The cake will rise above the mug rim and then settle — this is normal. It should look set and slightly domed with a few wet-looking spots on top.
5
Let cool in the mug for 1 minute. The center will firm up as it rests. If the top still looks very wet after resting, microwave 15 seconds more.
6
Slide a spoon in along the edge and serve directly from the mug, or tip onto a small plate. Optional: finish with a light dusting of almond-flour or an extra drizzle of honey.

Safety & Storage
Cooking Temperature
{"classification":"cooking-temperature","text":{"text":"Microwave on high for 1 minute 30 seconds. The cake should appear set with no visible liquid egg. If center appears undercooked, microwave an additional 15 seconds. Egg should reach at least 160°F internally."}}
High Risk Population
This recipe contains eggs cooked via microwave. Pregnant individuals, young children, elderly, and immunocompromised persons should ensure eggs are fully cooked before consumption.
Cross Contamination
Use a clean, microwave-safe mug. If substituting frozen blueberries, ensure they are thawed safely and pat dry to avoid excess moisture affecting cooking.
Handling
Let the mug cake cool for 1 minute before serving. The center will firm up during rest time. Use oven mitts when handling the hot mug.
Storage
Mug cake is best served immediately. If storing leftovers, refrigerate within 2 hours in an airtight container for up to 2 days. Reheat to 165°F before consuming.
Equipment Safety
Only use microwave-safe mugs or bowls. Do not use metal utensils, foil, or containers not marked microwave-safe. Stop microwaving immediately if you see sparking.
Pro Tips
Technique
Press a few frozen blueberries slightly between your fingers before folding them in—they'll bleed a gorgeous purple swirl through the batter as they cook, making the cake look way more impressive than the effort suggests.
Substitution
Out of honey? Maple syrup works exactly the same. Out of fresh lemon? A frozen lemon zest cube (yes, I keep them in an ice tray in my freezer—don't judge) thawed in the batter is indistinguishable. The point is: keep moving.
From the chef
Some nights you need cake in four minutes, not forty. This mug cake is what happens when I raid my freezer for frozen blueberries and my pantry for almond flour—I refuse to accept that a single-serving dessert has to come from a box. The lemon zest is doing heavy lifting here, brightening the whole thing into something that actually feels intentional, not desperate. Nobody needs to know you built this from a handful of ingredients in under ten minutes.
