  • Total Time: 1 hour
  • Yield: 8 servings 1x

Ingredients

Scale

For the Cake:

  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • 1 teaspoon cinnamon
  • ½ teaspoon nutmeg
  • ½ teaspoon salt
  • ½ cup unsalted butter, softened
  • ¾ cup brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • ½ cup milk
  • 2 apples, peeled, cored, and diced

For the Caramel Filling:

  • ½ cup caramel sauce (store-bought or homemade)
  • 1 teaspoon sea salt (optional, for a salted caramel touch)

For the Crumble Topping:

  • ½ cup all-purpose flour
  • ¼ cup brown sugar
  • ¼ cup unsalted butter, melted
  • ½ teaspoon cinnamon

Instructions

  • Preheat the Oven – Set your oven to 350°F (175°C) and grease a 9-inch cake pan.
  • Prepare the Cake Batter – In a bowl, whisk together flour, baking powder, baking soda, cinnamon, nutmeg, and salt. In a separate bowl, beat butter and brown sugar until creamy, then mix in eggs and vanilla extract. Gradually add the dry ingredients and milk, stirring until smooth. Fold in the diced apples.
  • Make the Crumble Topping – In a small bowl, combine flour, brown sugar, melted butter, and cinnamon. Mix until crumbly.
  • Layer the Cake – Pour half of the batter into the prepared cake pan. Drizzle caramel sauce evenly over the batter, then pour the remaining batter on top.
  • Add the Crumble – Sprinkle the crumble topping evenly over the cake.
  • Bake the Cake – Place in the oven and bake for 40-45 minutes, or until a toothpick inserted in the center comes out clean.
  • Cool & Serve – Let the cake cool for 10 minutes before slicing. Serve warm for the best molten caramel effect.

Notes

  • Use Granny Smith or Honeycrisp apples for the best balance of sweetness and tartness.
  • For extra indulgence, drizzle more caramel sauce before serving.
  • Store leftovers in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days.
  • To reheat, microwave for 15-20 seconds or warm in the oven at 300°F (150°C) for 10 minutes.
