Caramel Apple Spice Cake

Caramel apple spice cake is everything cozy baking should be, tender, moist, and full of warming spices. Chunks of fresh Granny Smith apples add juicy bites in every slice, applesauce keeps the crumb soft, and the maple buttercream with a thick layer of caramel makes it a seasonal favorite.

I developed this apple cake recipe back in 2018 as a cute little three-layer, 6-inch cake topped with a caramel drizzle. When I revisited the recipe, though, I realized I preferred the look (and the slice size!) of an 8-inch cake, it feels more at home on the table once a few pieces are served. I also made a couple of tweaks: swapping in some almond flour for extra moisture and tucking caramel between the layers as well as on top. The result is still true to the original with plenty of warm spices, juicy apples, and a creamy, fall-inspired buttercream, but just a little more refined and irresistible.

Key Ingredients & Test Notes

• All Purpose Flour with a 10-11% protein level is strong enough to support the apple chunks and added moisture while still delivering a tender cake crumb.
  • Test Note: Cake flour would be too fragile and bread flour would result in a drier cake.
• Almond Meal, basically ground whole almonds contributes a slightly nutty flavor and makes the cake more tender. It’s subtle but adds a bakery-quality touch.
  • Test Note: Make your own by blending whole almonds in a food processor or blender into a fine crumb.
• Unsweetened Applesauce adds extra moisture without weighing down the cake, giving an extra boost of apple flavor throughout.
• Brown Sugar & Granulated Sugar combined provide sweetness, moisture, and a bit of molasses notes from dark brown sugar.
  • Test Note: Light or dark brown sugar can be used interchangeably.
• Sunflower Oil replaces butter with a neutral flavor, that keeps the cake extra moist without competing with the apples and spices.
• Apples like Granny Smith, Honeycrisp, or Pink Lady are the best apple choices for this cake. They hold their shape while baking and give the cake a nice balance of sweet and tart flavor.
  • Test Note: The size of apple chunk matters. Grated apple is too small and will get lost in the batter, while large chunks are too big and sink to the bottom. Diced apple pieces about the size of a pea are the best size for this cake.
• Warming Fall Spices of cinnamon, nutmeg, ginger, and cloves are the familiar favorites that play well together without overpowering the apples.
  • Test Note: Swap out for chai spice or pumpkin spice, add a little cardamom or allspice too!
• Maple Buttercream and Caramel are the final touches! Maple brings earthy sweetness to the frosting, while the caramel sauce adds a decadent gooey layer between the cake.
  • Test Note: Make homemade caramel ahead and store it in the fridge until ready to use.

Step-by-Step

Helpful Tips

• Weigh Your Ingredients: Using a small kitchen scale to be exact. This is a moist cake and to little or too much of an ingredient will alter the final result.
• Use Baking Strips: For even layers with minimal doming, wrap the cake pans in baking strips before placing them in the oven.
• Check Doneness Early: Start checking the cakes at 28 minutes since oven times vary. Look for a few moist crumbs on the toothpick, not raw batter.
• Chill Before Frosting: Cooling the cake layers before assembling makes them sturdier and much easier to trim, stack, and frost cleanly.
• Frosting Tip: A crumb coat helps lock in stray crumbs, so the final frosting looks smooth and professional. Add just a thin layer of frosting, then refrigerate the cake for 10-15 minutes, continue with remaining frosting.

Leftovers & Storage

• Room Temperature: If your kitchen is cool, the frosted cake will stay fresh in an airtight container at room temp for about a day.
• Refrigerator: For longer storage, keep the cake in the fridge, in an airtight container or cake dome. It’ll stay fresh for 3–4 days. Let slices come to room temp before serving so the frosting softens back up.
• Freezer: You can freeze the cake layers (unfrosted) for up to 2 months. Wrap them tightly in plastic wrap, then foil, and thaw overnight in the fridge before frosting.
• Pro Tip: A quick 8-10 second zap in the microwave makes a chilled slice taste freshly baked again, especially with the caramel filling.
