Add the granulated sugar to a clean, dry pot. Cook over medium heat on the stovetop, stirring slowly with a rubber spatula. Don't let it hit the sides of the pot.
200 grams granulated sugar
The sugar will clump and turn golden. After a few minutes, it will start to melt and break down. Keep stirring until it is completely liquid and an amber color.
Take the pot off the heat and add butter. It will bubble viciously. Stir until the butter is mostly mixed in.
84 grams unsalted butter
Pour in the heavy cream and immediately whisk it in. Once fully combined, whisk in the vanilla and salt.
120 grams heavy cream, 1 teaspoons vanilla extract, 2 teaspoons salt
Pour the hot salted caramel into a glass jar. Let it cool for 30 minutes at room temperature. Cover and store in the refrigerator for up to 1 week.
Crumble
Add melted butter, flour, sugar, and brown sugar to a small bowl. Whisk until pea-sized lumps form and chill in the fridge while you make the cake batter.
56 grams unsalted butter, 70 grams all purpose flour, 60 grams granulated sugar, 35 grams brown sugar
Cake
Preheat the oven to 350 degrees Fahrenheit (180 degrees Celsius). Line a 9X9-inch square baking pan with parchment paper. Set aside.
Whisk all purpose flour, sugar, baking powder, cinnamon, nutmeg, and salt together in a large bowl.
Add the softened butter to the dry ingredients. Beat with an electric mixer or stand mixer on low speed for 3-5 minutes until it looks like wet sand.
150 grams unsalted butter
Add eggs one at a time, mixing until combined. Add the vanilla and buttermilk, mixing on medium speed until combined. Set aside.
2 large eggs, 2 teaspoon vanilla extract, 120 grams buttermilk
Chop the apples into ½ inch square pieces and add them to a separate large mixing bowl. Toss with cinnamon until coated.
2-3 medium apples, ½ teaspoon ground cinnamon
Pour the batter into the prepared pan, spreading into an even layer. Sprinkle the cinnamon apples on top of the batter, then add the crumble on top.
Bake for 50-60 minutes until golden brown and a toothpick inserted in the center comes out clean.
Remove the cake from the oven, let cool in the hot pan for 10 minutes, and then transfer to a wire rack to cool completely.
Once completely cool, cut into slices and add caramel drizzle. Top with flaky salt and serve!
