Three layers of soft maple cake, tender sauteed apples, and buttery crumb topping collide in this indulgent maple pecan apple buckle that's perfect for ANY fall occasion!
In a medium saucepan, combine all filling ingredients and saute apples over medium-high heat until crisp tender. Set aside.
Cake Batter
Preheat oven to 350F. Lightly grease a 9x13 baking pan. Set aside.
In a medium bowl, beat sugar, syrup, and melted butter until smooth. Whisk in eggs, vanilla, yogurt, and milk until smooth. Gradually fold in flour, baking powder, and salt until batter is smooth.
Scrape batter into prepared pan and smooth top. Spoon apple mixture over top.
Crumb Topping
In small bowl, combine all topping ingredients until crumbly. Evenly sprinkle over apple filling.
Bake buckle at 350F 25-30 minutes or until golden-brown and a toothpick tests done. Let cool completely on a wire cooling rack then drizzle with maple syrup if desired. Slice into squares and serve. Enjoy!
