Polish Apple Charlotte Recipe with Crumbly Topping

Start by grating the cold butter directly into a mixing bowl. Ensure that it is finely grated for even mixing.

Next, add the all-purpose flour and baking powder. Use your fingers to mix these ingredients together until they resemble a crumbly texture.

Then, incorporate the egg, powdered sugar, and vanilla sugar. Mix quickly and shape the dough into a ball. Wrap it in plastic wrap and refrigerate for at least one hour to firm up.

While the dough is chilling, peel and dice the apples into small cubes. This will help them cook evenly and blend well into the dish.

Transfer the diced apples into a saucepan and sprinkle in the cinnamon. Cook them over low heat for about 20 minutes until they become soft and fragrant. Stir occasionally to prevent sticking.

Once the dough has chilled, remove it from the refrigerator and divide it into two equal parts. Grate the first part directly into a baking dish lined with parchment paper, covering both the bottom and sides.

Gently press the dough down and bake it in a preheated oven at 180°C (350°F) for 15 to 20 minutes, or until it turns a lovely golden brown.

After the base has baked and cooled slightly, pour the cooked apple filling over the top of the crust.

Grate the second half of the dough over the apple layer, ensuring it is evenly distributed. Smooth it out, and then return it to the oven at 200°C (400°F) for an additional 35 to 40 minutes or until the top is a delicious golden color.
