Cinnamon Apple Cake

Moist, tender, and warmly spiced — a deeply fragrant apple cake loaded with chunks of sweet, cinnamon-kissed apple in every bite, finished with a golden, crunchy cinnamon sugar crust on top. The kind of humble, honest cake that makes the whole house smell like autumn and tastes even better than it smells.

INGREDIENTS

• 3 cups all-purpose flour
• 1 teaspoon baking soda
• 0.5 teaspoons baking powder
• 0.5 teaspoons salt
• 2 teaspoons cinnamon
• 0.5 teaspoons nutmeg
• 0.25 teaspoons allspice
• 0.25 teaspoons ginger
• 1 cup granulated sugar
• 0.5 cups brown sugar, packed
• 1 cup vegetable oil
• 3 large eggs
• 2 teaspoons vanilla extract
• 0.25 cups whole milk or buttermilk
• 3 cups apples, peeled, cored, and diced into small chunks (about 3 medium apples)
• 1 cup chopped walnuts or pecans, toasted (optional)
• 2 tablespoons granulated sugar mixed with 1 teaspoon cinnamon (for topping)
• 0.5 cups unsalted butter (for glaze)
• 0.5 cups brown sugar, packed (for glaze)
• 2 tablespoons whole milk (for glaze)
• 1 teaspoon vanilla extract (for glaze)
• pinch of salt (for glaze)

STEPS

1. Preheat and prep: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or a 10-inch bundt pan generously with butter and dust lightly with flour, tapping out the excess. Set aside.
2. Mix the dry ingredients: In a large bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, nutmeg, allspice, and ginger until evenly combined.
3. Mix the wet ingredients: In a separate large bowl, whisk together the granulated sugar, brown sugar, and vegetable oil until smooth. Add the eggs one at a time, whisking well after each. Stir in the vanilla extract and milk or buttermilk until everything is smooth and glossy.
4. Combine: Pour the dry ingredients into the wet ingredients and fold gently with a rubber spatula until just combined — do not overmix. A few small lumps are fine. Fold in the diced apples and toasted nuts if using with just a few extra strokes. The batter will be very thick and loaded with apple chunks — this is exactly right.
5. Fill the pan: Spread the thick batter evenly into the prepared pan, smoothing the top with a spatula. Sprinkle the cinnamon sugar topping evenly over the entire surface for a gorgeous, lightly caramelized, crunchy crust.
6. Bake: Bake at 350°F for 45–55 minutes for a 9×13-inch pan or 60–70 minutes for a bundt pan, until the top is deep golden brown, the edges have pulled away slightly from the sides, and a toothpick inserted into the center comes out clean or with just a few moist crumbs. If the top browns too quickly tent loosely with foil after 40 minutes.
7. Make the brown butter glaze: While the cake is in its final minutes of baking, melt the butter in a small saucepan over medium heat. Continue cooking, swirling occasionally, until the butter turns golden and smells deeply nutty and caramelized — about 3–4 minutes. Add the brown sugar and milk and stir constantly until the sugar dissolves and the glaze comes to a gentle boil. Cook for 1 minute then remove from heat. Stir in the vanilla extract and pinch of salt.
8. Glaze and serve: Let the cake cool in the pan for 15 minutes. Drizzle the warm brown butter glaze generously over the top of the warm cake, letting it soak in and run down the sides. Let the glaze set for 10 minutes before slicing and serving.

NOTES Tips: A mix of apple varieties makes the most flavorful cake — Granny Smith adds tartness and holds its shape during baking while Honeycrisp or Fuji adds natural sweetness and juiciness. Dicing the apples into small, even chunks ensures they distribute evenly throughout the batter and cook through completely. Vegetable oil rather than butter keeps this cake extraordinarily moist for days — butter-based apple cakes dry out much faster. Do not overmix the batter once the flour is added — fold only until the flour disappears for the most tender crumb. The brown butter glaze is not optional — the nutty, caramel depth it adds ties the whole cake together and elevates it from a simple apple cake into something truly extraordinary. This cake keeps beautifully covered at room temperature for up to 3 days or refrigerated for up to 1 week and is honestly even better on day two once the flavors have deepened.
