Easy German Apple Sheet Cake - cooking recipe

Ingredients

1 tablespoon butter
14 tablespoons unsalted butter, at room temperature
1 cup white sugar
3 cups all-purpose flour
4 teaspoons baking powder
lemon, zested and juiced
1 pinch salt
3 eggs, beaten
3 1/4 pounds apples - peeled, cored, and thinly sliced
2 tablespoons raisins (optional)

Preparation

Preheat oven to 400 degrees F (200 degrees C). Grease a large, 12x18-inch rimmed baking sheet with 1 tablespoon butter.
Combine 14 tablespoons butter and sugar in a large bowl; beat with an electric mixer until smooth and creamy.
Mix flour, baking powder, lemon zest, and salt in a bowl. Alternate adding flour mixture and eggs to the creamed butter mixture. Spread batter onto the prepared baking sheet; dough is very sticky, so use a spatula to spread it onto the tray. Distribute sliced apples evenly on top and drizzle with lemon juice. Sprinkle with raisins.
Bake in the preheated oven until set and lightly browned, about 30 minutes.
