Step 1

Preheat oven to 350 degrees F. Coat a baking sheet with cooking spray.

Step 2

Using a serrated knife, make a criss-cross patter in the bread slicing 1 inch apart, cutting almost all the way to the bottom but being careful not to cut through completely. Place bread on baking sheet. Evenly pour butter between each bread section.

Step 3

In a medium bowl, combine dry cake mix and brown sugar; mix well. Add apples and toss until evenly coated. Evenly sprinkle apple mixture between between each of the bread sections, being careful not to break the bread apart. Sprinkle any remaining mixture over the bread.

Step 4

Bake 25 to 30 minutes, or until bread is crispy on top and bottom.

Step 5

In a small bowl, whisk confectioners' sugar and milk until smooth. Drizzle over warm bread and serve immediately.
