Easy Apple Cinnamon Sheet Cake Recipe for Fall

This apple cinnamon sheet cake is a soft, warmly spiced dessert made for sharing. Tender apples are folded into a simple vanilla batter, then the cake is baked in a shallow pan so every square gets a golden edge and a generous cinnamon finish. It is easier than a layer cake, faster than a pie, and just right for fall potlucks, school treats, or an afternoon coffee break.

The batter uses everyday ingredients and does not require a mixer. Add a simple powdered-sugar glaze after cooling, or serve each square plain with a spoonful of whipped cream. Because the cake is baked in a sheet pan, it cools quickly and gives you plenty of neat portions.

Why You’ll Love This Apple Cinnamon Sheet Cake

• Quick to assemble: The batter mixes in one bowl with a whisk and spatula.
• Soft, not dry: Sour cream and apples keep the crumb tender for several days.
• Great for groups: A 9-by-13-inch pan gives you generous squares for a gathering.
• Flexible fruit: Use apples, pears, or a mix of both depending on the season.
• Simple finish: Cinnamon sugar, glaze, or a dusting of powdered sugar all work beautifully.

Ingredients

• 2 cups all-purpose flour
• 2 teaspoons baking powder
• 1/2 teaspoon baking soda
• 1/2 teaspoon fine salt
• 2 teaspoons ground cinnamon
• 1/2 cup unsalted butter, melted and cooled slightly
• 3/4 cup granulated sugar
• 1/2 cup packed light brown sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 3/4 cup sour cream or plain Greek yogurt
• 3 medium apples, peeled, cored, and diced
• 2 tablespoons coarse sugar, optional

Optional Glaze

Whisk 1 cup powdered sugar with 2 tablespoons milk and 1/2 teaspoon vanilla. Add a few drops of milk if needed until the glaze drips slowly from a spoon. For a caramel note, replace the milk with apple cider.

How to Make Apple Cinnamon Sheet Cake

1. Prepare the pan. Heat the oven to 350°F. Grease a 9-by-13-inch metal baking pan and line the bottom with parchment if you want easy lifting.
2. Whisk the dry ingredients. Combine the flour, baking powder, baking soda, salt, and cinnamon in a medium bowl.
3. Mix the sugars and butter. In a large bowl, whisk the melted butter, granulated sugar, and brown sugar until glossy and smooth.
4. Add the eggs and dairy. Whisk in the eggs one at a time, then add vanilla and sour cream. The mixture may look slightly thick but should be evenly combined.
5. Combine gently. Add the dry ingredients and fold with a spatula just until no flour streaks remain. Avoid vigorous mixing.
6. Fold in the apples. Add the diced apples and fold only until distributed. Scrape the batter into the prepared pan and smooth the surface.
7. Add the topping. Sprinkle the top with the remaining 1/2 teaspoon cinnamon and coarse sugar if using.
8. Bake. Bake for 30 to 38 minutes, rotating the pan once halfway through. The cake is ready when the center springs back lightly and a toothpick comes out with moist crumbs.
9. Cool and finish. Cool in the pan for at least 30 minutes. Drizzle with glaze once barely warm or completely cool, then cut into squares.

Tips and Variations

• Pick firm apples: Granny Smith, Honeycrisp, Pink Lady, or Braeburn keep their shape during baking.
• Dice, do not grate: Small cubes give you pockets of apple without releasing too much juice.
• Do not overbake: Begin checking early because shallow cakes can finish quickly.
• Add nuts: Fold 1/2 cup chopped pecans or walnuts into the batter.
• Use raisins: Add 1/3 cup golden raisins for a classic apple-cinnamon flavor.
• Make it citrusy: Add 1 teaspoon orange zest to the batter and use orange juice in the glaze.
• Try a streusel: Top with a mixture of flour, brown sugar, cinnamon, and butter before baking.
• Use a glass pan: Reduce the oven to 325°F and expect the cake to need a few extra minutes.

Storage and Reheating

Cover the cooled cake and keep it at room temperature for up to 2 days. Store it in the refrigerator for up to 5 days if glazed with a dairy-based topping or if your kitchen is warm. Let slices sit at room temperature before serving so the crumb softens again. To warm a piece, microwave it for 10 to 15 seconds or place several pieces in a 300°F oven for 5 minutes.

Freeze unglazed squares for up to 2 months. Wrap them individually, place them in a freezer bag, and thaw overnight in the refrigerator. Add the glaze after thawing so it stays bright and smooth.

Frequently Asked Questions

How do I make Apple Cinnamon Sheet Cake – Easy Fall Dessert Recipe?

Whisk a sour-cream cake batter, fold in diced apples, spread it in a 9-by-13-inch pan, and bake at 350°F until golden and set.

Can I leave the apple skins on?

Yes, especially if you use thin-skinned apples. Peeling gives a softer texture, while leaving the skins on adds color and a little chew.

Why is my sheet cake dense?

Too much flour, overmixing, or expired leaveners can make the cake dense. Measure flour lightly, fold only until combined, and check that the baking powder is fresh.

Can I use applesauce instead of sour cream?

Replace up to half of the sour cream with unsweetened applesauce. A full swap makes the crumb softer and less rich, so reduce added sugar slightly if desired.

How do I cut neat squares?

Cool the cake fully, use a sharp knife, and wipe the blade between cuts. If glazed, let the glaze set for 15 minutes before slicing.

Serving Ideas

Serve the cake with coffee, tea, or warm apple cider. Add a scoop of vanilla ice cream for dessert, or place small squares on a brunch platter with fruit and toasted nuts. If you like a little salt with your sweetness, finish the glaze with a pinch of flaky salt. The shallow shape also makes it easy to transport without worrying about a delicate frosting layer.

Make-Ahead Notes for Fall Baking

The batter can be mixed shortly before baking, but it is best not to let it sit for a long time because the leaveners begin working as soon as they meet the wet ingredients. You can prepare the apples and dry ingredients a day ahead, then finish the batter when you are ready to bake. If you are taking the cake to a gathering, cool it completely before covering it so trapped steam does not soften the top.

For the most even bake, spread the batter all the way into the corners and keep the center level. Rotate the pan once if your oven has a hot spot. When baking with eggs for family or guests, the USDA’s egg-safety guidance is a useful reference.

Choosing a Topping

A glaze gives the cake a polished bakery look, while cinnamon sugar keeps the finish simple and slightly crisp. Streusel adds the most texture and makes the dessert feel extra generous. You can also spread a thin layer of cream cheese frosting over the cooled cake, but let the cake cool fully first so the frosting does not melt.
