Whip up this stunning yet super simple Apple Caramel Upside-Down Cake! Imagine a buttery soft cinnamon cake baked over sweet apples swimming in gooey caramel. It looks fancy, tastes amazing, but is easy enough for anyone. Pure comfort food magic!

Ingredients

For the Caramel Apple Layer:

  • Caramel Sauce: 1/3 cup (store-bought jarred kind works great!)
  • Apples: 2 medium, firm & tart (like Honeycrisp or Granny Smith), peeled, cored, sliced ¼-inch thick

For the BUTTERY SOFT Cake Batter:

  • Unsalted Butter: 125g (½ cup + 1 tbsp), very soft
  • Granulated Sugar: 110g (just over ½ cup)
  • Large Eggs: 2, room temperature if possible
  • Vanilla Essence: 1 tsp
  • All-Purpose Flour: 100g (about ¾ cup + 1 tbsp)
  • Ground Cinnamon: 1 tsp
  • Baking Powder: 1 tsp
  • Baking Soda: ½ tsp
  • Salt: ¼ tsp (if using unsalted butter)

Instructions

  1. Prep Oven & Pan: Heat oven to 350°F (175°C). Pour caramel into an ungreased 9-inch round or square pan, swirling to coat the bottom. Arrange apple slices tightly over the caramel. Set aside.
  2. Mix Dry Stuff: In a medium bowl, whisk together flour, cinnamon, baking powder, baking soda, and salt. Set aside.
  3. Cream Butter & Sugar: In a large bowl, beat the softened butter with an electric mixer until creamy. Gradually add sugar and beat on medium-high until light, pale, and fluffy (about 3-4 minutes). Scrape the bowl!
  4. Add Eggs & Vanilla: Beat in eggs one at a time, mixing well after each. Stir in vanilla. (Don’t worry if it looks slightly split).
  5. Combine Wet & Dry: Add the dry ingredients to the wet ingredients. Mix on low speed or fold with a spatula just until no flour streaks remain. Do not overmix! The batter will be thick.
  6. Assemble: Gently spoon the thick batter over the apples in the pan. Carefully spread it evenly to the edges, covering the apples completely.
  7. Bake: Bake for 25-30 minutes, until golden brown and a toothpick inserted into the cake center comes out clean (or with moist crumbs, no wet batter).
  8. Cool & Flip (The Fun Part!): Let the cake cool in the pan on a wire rack for 15-20 minutes (this is important!). Run a thin knife around the edge to loosen. Place a large serving plate over the pan. Carefully and quickly, flip the whole thing over. Lift off the pan. Done!

Notes

  • Serving: Amazing served warm! Try it with a scoop of vanilla or salted caramel ice cream, or a dollop of whipped cream.
  • Tips & Tricks:
    • Make sure butter is really soft for the best texture.
    • Don’t overmix the batter once flour is added – keeps it tender!
    • The 15-20 min cooling time before flipping is key – prevents sticking and breaking.
    • If an apple sticks to the pan after flipping, just gently place it back on the cake. No biggie!
    • Want nuts? Sprinkle chopped pecans or walnuts over the caramel before adding apples.
  • Storage: Cool completely. Store leftovers airtight at room temp for 1-2 days or in the fridge for 3-4 days.
  • Reheating: Gently warm slices in the microwave (15-20 secs) or wrapped in foil in a low oven (300°F/150°C for 5-10 mins).
