Preheat the Oven: Preheat your oven to 350°F (175°C). This ensures that the cake will bake at the right temperature from the start.Grease a springform pan with butter or non-stick spray to prevent the cake from sticking.
Cream Butter and Sugar: In a large mixing bowl, beat together 1/2 cup butter and 1 2/3 cups sugar until the mixture becomes light and fluffy. This process incorporates air into the batter, making the cake texture soft and airy.
Add Eggs and Vanilla: Beat in 2 eggs, one at a time, ensuring each egg is fully incorporated before adding the next. This step ensures the eggs blend smoothly with the butter and sugar. Add 1 1/2 teaspoons vanilla and mix until the batter is smooth and fragrant.
Mix in Dry Ingredients: In a separate bowl, whisk together the 1 1/2 cups flour, 1 teaspoon baking soda, 1 teaspoon salt, 1 1/2 teaspoons cinnamon, and 1/2 teaspoon nutmeg. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix, as this could result in a dense cake.
Add Apples: 3 cups of diced & peeled apples (about 2 large apples) should be added to the batter. Gently fold the apples into the batter until evenly distributed. The apples will add moisture, flavor, and texture to the cake.
Optional Nuts: If you’re using 1/4 cup chopped pecans or walnuts, fold them into the batter at this stage. They add extra crunch and a nutty flavor that pairs beautifully with the apples.
Sugar and Cinnamon Topping: In a small bowl, combine cinnamon and sugar. Sprinkle this mixture over the top of the cake batter. This creates a sweet and spicy crust that will form during baking, giving the cake a nice flavor boost.
Bake the Cake: Pour the batter into the prepared springform pan and spread it evenly. Bake the cake in the preheated oven for about 1 hour and 15 minutes. Check the cake for doneness by inserting a toothpick or cake tester into the center. If it comes out clean, the cake is ready.
Cool and Serve: Let the cake cool for at least 15-20 minutes in the pan. Once cooled, remove the sides of the springform pan and transfer the cake to a cooling rack to cool completely. Slice and enjoy your moist, aromatic Swedish Apple Cake!
