Preheat the oven to 350°F (175°C). Butter a 5×7-inch baking dish and line it with parchment paper.
In a large bowl, whisk together the flour, oats, sugar, and salt.
Add the cold, cubed butter to the bowl. Use your fingertips, a pastry blender, or two butter knives to rub the butter into the flour mixture until it forms a sandy, crumbly texture with some small clumps.
Add the egg yolk and vanilla. Stir with a fork or use your fingers to mix until the dough is fully combined and holds together when pressed gently.
Scoop out 3/4 cup of the dough and press it firmly into the prepared baking dish to form the crust. Place the remaining dough in the fridge, then bake the crust for 15 minutes.
After baking, take the pan out of the oven and spread the jam evenly over the warm crust.
Sprinkle the chilled dough evenly over the jam layer.
Return the pan to the oven and bake for 40 to 45 minutes, until the top is golden and the edges are lightly browned.
Let the bars cool completely to room temperature. Then, lift them out of the baking dish by pulling up the edges of the parchment paper. Slice into bars and serve.
Notes
Use The Right Baking Dish Size: A 5×7-inch baking dish works best for this small batch recipe. Using a larger dish may result in thinner bars.
Line Your Baking Dish: Butter the baking dish first, then add parchment paper. The butter helps the paper stick and makes it easier to lift the bars out after baking.
Press The Crust Firmly: Press the crust layer down firmly so it holds together well once baked.
Spread Jam Carefully: Leave a small border around the edges when spreading the jam. This helps keep the edges neat and makes it easier to slice the bars cleanly.
Cool Completely Before Slicing: Let the bars cool fully to get clean, even slices.
If doubling this recipe, bake the bars in an 8x8-inch baking dish.
