Description
Toasted walnut–oat crumb crust, a creamy no-bake cheesecake layer, and a thick cinnamon apple-caramel topping that chills into clean, sliceable bars.
Ingredients
- Rolled oats: 1 cup (80 g)
- Graham-style crumbs (or digestive biscuit crumbs): 1/2 cup (50 g)
- Toasted walnuts, finely chopped: 1/2 cup (60 g)
- Light brown sugar: 2 tablespoons (25 g)
- Ground cinnamon: 1/2 teaspoon (1 g)
- Fine salt: 1/4 teaspoon
- Unsalted butter, melted: 6 tablespoons (85 g)
- Full-fat cream cheese, softened: 16 oz (454 g)
- Sweetened condensed milk: 1/2 cup (170 g)
- Vanilla extract: 1 teaspoon (5 ml)
- Fine salt: 1/8 teaspoon
- Heavy cream, cold: 1 cup (240 ml)
- Unsalted butter: 2 tablespoons (28 g)
- Honeycrisp or Granny Smith apples, peeled and diced small: 2 medium apples (about 300 g)
- Ground cinnamon: 1 teaspoon (2 g)
- Caramel sauce (stirred, jarred), warm if needed: 1/2 cup (170 g)
- Light brown sugar: 1 tablespoon (12 g)
- Apple cider or water: 2 tablespoons (30 ml)
- Cornstarch: 1 tablespoon (8 g)
- Cold water (to make a slurry): 1 tablespoon (15 ml)
- Optional garnish: chopped toasted walnuts
Instructions
- Line and prep pan: Line an 8-inch square pan with parchment (leave overhang for lifting). Lightly grease the parchment with cooking spray.
- Toast the crumb base: In a large bowl, combine oats (1 cup / 80 g), graham-style crumbs (1/2 cup / 50 g), chopped walnuts (1/2 cup / 60 g), brown sugar, cinnamon, and salt. Drizzle in melted butter (6 tablespoons / 85 g) and mix until evenly sandy.
- Bake briefly for flavor (recommended): Transfer crumb mixture to a baking sheet and bake at 350°F (175°C) for 8–10 minutes, stirring once. You want a fragrant, slightly deeper golden color. Cool 5 minutes.
- Press crust: Spoon warm crumb mixture into the lined pan and press firmly into an even layer (I use the bottom of a measuring cup). Chill while you make the filling.
- Make cheesecake layer: In a mixing bowl, beat softened cream cheese until smooth. Beat in sweetened condensed milk, vanilla, and salt until creamy and uniform.
- Whip cream: In a separate bowl, whip cold heavy cream (1 cup / 240 ml) to soft peaks—when you lift the beaters, the cream should hold shape but look cloudlike, not stiff.
- Combine: Fold whipped cream into the cream cheese mixture in 2–3 additions until you don’t see streaks. Spread over the chilled crust. Smooth the top. Chill 15 minutes to firm slightly.
- Cook apple-caramel topping: Melt butter in a saucepan over medium heat. Add diced apples and cook 5–7 minutes, stirring, until slightly softened.
- Thicken caramel: Stir in caramel sauce, brown sugar, cinnamon, and apple cider (or water). In a small cup, stir cornstarch with cold water to make a slurry. Pour slurry into the simmering topping and cook 1–2 minutes, stirring constantly, until thick and glossy.
- Cool topping: Remove from heat. Let topping cool until warm, not hot (about 20–30 minutes). It should be thick enough to mound slightly on a spoon.
- Assemble: Spoon topping over the cheesecake layer and spread gently to the edges.
- Chill to set: Cover and refrigerate at least 4 hours, ideally overnight, until fully firm.
- Slice: Lift bars from the pan using parchment. Slice with a warm, clean knife (wipe between cuts). Serve chilled.
Notes
– If your caramel sauce is very thick, warm it gently so it blends smoothly.
– Soft peaks for whipped cream are key—stiff peaks can make the cheesecake layer feel dense.
– If the topping seems runny after cooking, it needs 1–2 extra minutes on the stove.
– For the cleanest slices, chill overnight and wipe the knife between cuts.
