Step 1: Preheat the oven

• Preheat your oven to 375°F (190°C). Grease a 9-inch pie dish or ovenproof skillet with butter.

Step 2: Caramelize the apples

• Heat a large skillet over medium heat and melt the butter. Add the apple slices and sprinkle with 2 tablespoons of granulated sugar and the cinnamon.
• Sauté for 5–7 minutes until the apples are tender and slightly caramelized. Remove from heat and let cool slightly.

Step 3: Prepare the batter

• In a mixing bowl, whisk the eggs until frothy. Add the milk, heavy cream, vanilla extract, the remaining sugar, flour, and salt. Whisk until the batter is smooth and well combined.

Step 4: Assemble the clafoutis

• Arrange the caramelized apple slices evenly in the prepared baking dish. Pour the batter over the apples, ensuring they are evenly covered.

Step 5: Bake the clafoutis

• Place the dish in the oven and bake for 35–40 minutes, or until the clafoutis is puffed and golden brown. The center should be set but slightly custard-like.

Step 6: Cool and serve

• Remove from the oven and let cool for 5–10 minutes. Dust with powdered sugar before serving. Enjoy warm or at room temperature.
