Method
Make the crust
- Heat the oven to 350°F.
- Line a 9x13-inch baking pan with parchment paper, leaving overhang on two sides, and lightly grease the parchment.
- Whisk 2 cups of the flour with 1/2 cup of the brown sugar and the salt.
- Stir in 3/4 cup melted butter until evenly moistened.
- Press the crust mixture firmly into an even layer in the prepared pan.
- Bake for 15–18 minutes, until the crust looks dry and the edges are lightly golden.
- Cool for 10 minutes.
Make the filling
- Beat the cream cheese with 1/2 cup of the granulated sugar until smooth, scraping down the bowl as needed.
- Beat in the eggs one at a time.
- Mix in the vanilla just until combined.
Make the apple layer
- Toss the diced apples with the remaining 1/4 cup granulated sugar, 1 tablespoon flour, and 1 teaspoon cinnamon.
Make the streusel
- Stir together the remaining 1 cup flour, the oats, remaining 1/2 cup brown sugar, and remaining 1 teaspoon cinnamon.
- Work in 1/2 cup cold cubed butter with your fingertips or a fork until coarse clumps form.
Assemble and bake
- Spread the filling over the warm crust.
- Distribute the apples evenly over the filling.
- Scatter the streusel on top.
- Bake for 35–45 minutes, until the streusel is golden, the center is set, and the center of the filling reaches 160°F.
- Cool completely in the pan on a wire rack, about 1 hour.
- Refrigerate for at least 4 hours until thoroughly chilled.
Finish with caramel
- Warm the caramel sauce in a microwave-safe bowl in 10-second bursts, stirring until pourable.
- Drizzle the caramel over the chilled bars.
- Lift the bars from the pan using the parchment.
- Cut into 16 bars.
Notes
For neat slices, chill the bars thoroughly and wipe the knife between cuts. Store covered in the refrigerator for up to 4 days; freeze yes, wrapped well for up to 2 months. For a gluten-free swap, use a measure-for-measure gluten-free flour blend and certified gluten-free oats.
