Ingredients

1/4 cup coconut flour
1/4 cup powdered erythritol (or monk fruit sweetener)
1/2 tsp baking powder
1/8 tsp fine sea salt
2 large eggs
2 tbsp unsalted butter, melted
1 tsp lemon zest, finely grated
2 tsp fresh lemon juice
1/2 tsp pure vanilla extract
2 tbsp heavy cream

Instructions

1

Preheat the air fryer to 320 degrees F for 3 minutes. Lightly grease two 6-ounce ramekins or oven-safe mugs with butter.
2

In a bowl, whisk together 1/4 cup coconut flour, 1/4 cup powdered erythritol (or monk fruit sweetener), 1/2 tsp baking powder, and 1/8 tsp fine sea salt.
3

Add 2 large eggs, 2 tbsp melted unsalted butter, 1 tsp finely grated lemon zest, 2 tsp fresh lemon juice, 1/2 tsp pure vanilla extract, and 2 tbsp heavy cream. Whisk vigorously until a smooth batter forms with no lumps. Let it rest for 2 minutes - coconut flour absorbs liquid slowly.
4

Divide the batter evenly between the two prepared ramekins.
5

Place the ramekins in the air fryer basket and cook at 320 degrees F for 10 to 12 minutes, until the tops are set and a toothpick inserted in the center comes out clean.
6

Let the cakes cool in the ramekins for 3 minutes before serving. Serve warm, topped with a dusting of powdered erythritol or a small spoonful of whipped cream if desired.

Questions

Can I make Keto Coconut Flour Lemon Mug Cake dairy-free?

Yes. The dairy in this entry is 2 tbsp unsalted butter, melted, 2 tbsp heavy cream. Swap the butter for olive oil where it melts, or a plant-based block butter where it is creamed; the cream for full-fat coconut milk or an oat cooking cream. The richness shifts slightly, but the method does not change.

How long does Keto Coconut Flour Lemon Mug Cake keep?

Keep it covered in the refrigerator and eat it within three days.

Can I halve or double Keto Coconut Flour Lemon Mug Cake?

Yes. As written it serves 2. Every ingredient in this entry carries precomputed half and double quantities, and the app's batch dial rewrites them inside each step. Doubled, air-fry in batches; a crowded basket steams instead of crisping.
