3 cups apples, peeled, cored, and diced (about 3–4 medium apples)
2 cups all-purpose flour
1 cup granulated sugar (for the batter)
1/2 cup unsalted butter, softened
1/2 cup whole milk
2 large eggs
1 teaspoon vanilla extract
1 teaspoon baking soda
1 teaspoon ground cinnamon (for the batter)
1/2 teaspoon salt
1/4 cup granulated sugar (for the topping)
1 tablespoon ground cinnamon (for the topping)
Instructions
Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan or a standard bundt pan to ensure the cake doesn’t stick.
In a large mixing bowl, beat the softened butter and 1 cup of sugar together until the mixture is light and fluffy. This should take about 2 to 3 minutes using a hand mixer or stand mixer.
Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract and the milk until the mixture is smooth.
In a separate bowl, whisk together the flour, baking soda, 1 teaspoon of cinnamon, and salt. Gradually add these dry ingredients to the wet mixture, stirring just until combined. Be careful not to overmix the batter.
Gently fold the diced apples into the thick batter using a spatula. Ensure the apple pieces are evenly distributed throughout the mixture.
Spread the batter evenly into your prepared baking pan. In a small bowl, mix the 1/4 cup of sugar and 1 tablespoon of cinnamon. Sprinkle this mixture generously over the top of the batter.
Place the pan in the center of the oven and bake for 40 to 45 minutes. The cake is done when a toothpick inserted into the center comes out clean or with just a few moist crumbs.
Allow the cake to cool in the pan for at least 15 to 20 minutes before slicing. This helps the structure set and makes it easier to serve.
