1Prepare a batch of same-day focaccia dough up until it is time to tip the dough into the tray.
2Brown the butter. In a bowl, mix the browned butter with the light brown sugar, cinnamon, and vanilla extract. Set aside.
3Line the 9x13 inch parchment-lined tray with 2 tbsp melted salted butter.
4Transfer the proofed dough to the tray and gently stretch it to the edges.
5Mix 1/3 of the diced apples with half of the cinnamon filling, spread over the dough, and fold the dough.
6Flip the dough over and cover to finish proofing at room temperature for 1 to 1.5 hours.
7Preheat oven to 215C/420F, with the rack in the lowest position.
8Warm up the remaining cinnamon sugar butter filling and mix with the remaining 2/3 of diced apples.
9Spread the apple mixture evenly over the top of the dough and dimple in.
10Bake for 23-25 minutes.
11Whisk together powdered sugar, milk, vanilla extract, and a sprinkle of cinnamon to make a glaze.
12Once out of the oven, drizzle the glaze over the focaccia and brush it on the top, sides, and bottom.
13Transfer to a cooling rack for the glaze to harden.

Tips
You can use regular butter without browning it, but browning it provides more complex caramel notes.
The cinnamon sugar butter filling will harden as it cools, so you will need to warm it up to a drizzling consistency before applying it to the top of the dough.
Brush the bottom of the focaccia with the glaze by rubbing it in the tray.
