Ingredients

  • 1 1/2 cups brown sugar
  • 1/3 cup vegetable oil
  • 1 large egg
  • 1 cup buttermilk or milk + 1 tsp vinegar, or 1/2 cup yogurt + 1/2 cup milk
  • 1 teaspoon baking soda
  • 1 teaspoon vanilla extract
  • 2 1/2 cups all-purpose flour
  • 1 1/2 cups chopped apples use firm, crisp apples like Honeycrisp or Wealthy
  • 1/2 cup granulated sugar
  • 1 teaspoon cinnamon
  • 1 tablespoon butter melted

Instructions

  • Preheat oven to 325°F (165°C) and grease a 9x13-inch baking pan.
  • In a large bowl, whisk together brown sugar, oil, and egg until smooth.
  • Stir in buttermilk, baking soda, and vanilla until combined.
  • Add flour and mix gently until no dry streaks remain.
  • Fold in chopped apples until evenly distributed.
  • Pour the batter into the prepared baking pan and spread evenly.
  • In a small bowl, mix granulated sugar and cinnamon together; sprinkle evenly over the batter.
  • Drizzle melted butter on top of the cinnamon sugar layer.
  • Bake for 40–45 minutes, or until a toothpick inserted in the center comes out clean.
  • Let cool slightly before slicing — serve warm or at room temperature.

Notes

  • Apple Options: Honeycrisp, Fuji, or Gala apples give the best texture and flavor.
  • Make Ahead: The cake stays moist for up to 3 days at room temperature; wrap tightly for freshness.
  • Serving Idea: Serve warm with vanilla ice cream or caramel drizzle for an extra treat.
  • Dairy-Free Swap: Use almond milk with vinegar instead of buttermilk.
  • Texture Tip: Don’t overmix the batter — it keeps the crumb soft and fluffy.
