Ingredients
- Cake:
- 1 cup unsalted butter
- 1 cup water
- 2 cups + 2 tablespoons all-purpose flour
- 2 cups granulated sugar
- ½ teaspoon kosher salt
- 1 teaspoon baking soda
- 1 teaspoon cinnamon
- ½ cup sour cream
- 2 large eggs
- 1 medium apple, diced small or grated (about 1¼ cups)
- Icing:
- 3 tablespoons whole milk
- ¼ cup unsalted butter
- 2 cups powdered sugar
- ½ teaspoon vanilla extract
- 2 tablespoons caramel sauce
Instructions
- Prep Oven & Pan: Preheat oven to 350°F (175°C). Lightly grease a 10×15-inch jelly roll pan with nonstick spray.
- Boil Butter & Water: In a medium saucepan, bring butter and water to a boil while stirring frequently. Remove from heat and let cool slightly.
- Mix Dry Ingredients: In a large bowl, whisk together flour, sugar, salt, baking soda, and cinnamon.
- Mix Wet Ingredients: In another bowl, whisk together sour cream and eggs.
- Combine: Add the sour cream mixture to the dry ingredients. Fold in the apples. Slowly stir in the warm butter-water mixture until fully combined.
- Bake: Pour batter evenly into the prepared pan. Bake for 25–27 minutes, until the center springs back when lightly touched. Let cool slightly before icing.
- Make the Icing: In a microwave-safe bowl, combine butter and milk. Microwave in 45-second increments until the butter melts. Whisk in powdered sugar, vanilla, and caramel sauce until smooth. Adjust consistency with more powdered sugar or milk if needed (should be pourable but thick).
- Pour icing over the cake while it’s still slightly warm. Let set before slicing.
Notes
- No jelly roll pan? Use a 9×13 baking dish and add about 10 extra minutes to the baking time.
- For extra flavor, drizzle additional caramel sauce on top before serving.
- Best served the same day but can be stored covered at room temperature for up to 2 days.
