Ingredients
Method
- Preheat oven to 300°F (150°C). Line an 8-inch square pan with parchment paper.
- In a medium bowl, mix melted butter, granulated sugar, vanilla, and salt until smooth. Stir in flour until a dough forms. Press into pan evenly. Bake for 15 minutes.
- Meanwhile, prepare apple filling: toss sliced apples with flour, sugar, cinnamon, and nutmeg. Set aside.
- For the streusel: combine oats, brown sugar, cinnamon, and flour. Add cold butter and mix until crumbly.
- Raise oven temperature to 350°F (175°C). Layer apple mixture over warm crust and press gently.
- Sprinkle streusel evenly on top. Bake 30–35 minutes until golden brown and apples are tender.
- Cool at room temperature for 20 minutes, then refrigerate at least 2 hours before slicing.
- Drizzle salted caramel sauce before serving. Serve chilled, room temp, or slightly warmed.
Notes
For crisp streusel, freeze topping 30 minutes before baking. Don’t overmix crust dough to keep it tender. Use metal pans for even baking. Slice apples thinly and evenly for best texture. To make gluten-free, use a 1:1 gluten-free flour blend and certified gluten-free oats.
