• 3/4 cup unsweetened applesauce
• 3/4 cup jarred caramel dessert sauce
• 1 tbsp vanilla extract
• 3 large eggs
• 1 1/2 cups buttermilk

For the Salted Caramel Buttercream

• 3/4 tsp salt
• 3 cups powdered sugar

For the Caramel Apple Topping

How to Make the Cake

1. Preheat your oven to 350°F and prepare two 9-inch cake pans with parchment and grease.
2. In a large bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt.
3. In a separate bowl, beat together brown sugar and oil. Add applesauce, caramel sauce, and vanilla.
4. Mix in the eggs one at a time.
5. Alternately add dry ingredients and buttermilk in thirds, mixing gently.
6. Fold in the diced apples.
7. Divide batter evenly into pans and bake for about 40 minutes, or until a toothpick comes out clean.
8. Let cakes cool completely, then freeze for 30 minutes to firm them up.
9. Slice each cake in half to create four layers.
10. Stack layers with 3/4 cup frosting in between each, then frost the entire cake and decorate with swirls and caramel apples.

Making the Salted Caramel Buttercream

1. In a large pot, combine granulated sugar, buttermilk, 12 oz butter, and baking soda.
2. Bring to a boil and cook until the mixture hits 240°F, stirring constantly.
3. Transfer to a mixer and whip for 6 minutes.
4. Add remaining butter, salt, vanilla, and powdered sugar gradually.
5. Continue whipping until fluffy and luscious.

Decorating with Mini Caramel Apples

1. Wash and dry mini apples thoroughly. Insert sticks.
2. Melt soft caramels with heavy cream until smooth.
3. Dip apples, scrape off excess, and place on greased foil.
4. Chill until set before perching them atop your cake masterpiece.

Tips for Success

• Freeze the cake layers for easier stacking and smoother frosting—your future self will thank you.
• Don’t skip the applesauce; it brings moisture and subtle apple flavor.
• Caramel sauce tip: If it’s too thick to drizzle, microwave for 10 seconds.
• If your frosting looks curdled, just keep whipping! It’ll come together—kind of like life.
• Use a serrated knife or cake leveler for clean layers. Or wing it and call it rustic (we’ve all been there).

Olivia’s Note

This cake has been my go-to fall dessert ever since I whipped it up for a Halloween potluck five years ago. I remember lugging it into the school cafeteria, praying it wouldn’t topple over in the car. Not only did it survive the ride—it got devoured. Even my husband, who usually “doesn’t do cake,” asked for seconds. It’s since become our family’s “Welcome, Fall!” tradition.

What to Serve with This Fall Cake

Pair this rich, layered cake with something simple and complementary:

• A steaming mug of chai tea or black coffee
• A scoop of vanilla bean or cinnamon ice cream
• A cozy blanket and your favorite fall movie (may I suggest You’ve Got Mail?)

Hosting guests? Add a cheese board with apples and nuts for an elegant touch. Or keep it casual with cider and comfy socks. This cake plays well in any setting.

How to Store Your Caramel Apple Cake

• Room Temp: Covered and in a cool spot, it’ll keep for up to 2 days.
• Fridge: Store in an airtight container for up to 5 days. Let it sit at room temperature for 30 minutes before serving.
• Freezer: Freeze slices individually (wrapped tightly) for up to 2 months. Great for when you need a sweet pick-me-up!

Pro tip: Keep caramel apples separate if storing, or they may get sticky and droopy.

FAQs

Can I use homemade caramel instead of jarred?

Absolutely! Just make sure it’s pourable—not too thick or chewy.

Can I make this into cupcakes instead?

Sure can! Adjust the bake time to about 18–20 minutes and frost as desired.

Can I skip the caramel apples on top?

Of course. The cake stands beautifully on its own, but they do make a fun garnish.

What apples are best for this cake?

A firm, slightly tart apple, like Granny Smith or Honeycrisp, works wonderfully.

Can I make the buttercream ahead of time?

Yes! Store it in the fridge for up to 3 days and re-whip before frosting.
