Ingredients

½ cup all-purpose flour
½ cup old-fashioned oats
¼ cup granulated sugar
¼ teaspoon salt
¼ cup cold butter, cubed
1 large egg yolk
½ teaspoon vanilla extract
¾ cup jam or preserves of your choice

Instructions

Preheat the oven to 350°F (175°C). Grease a 5×7-inch baking dish and line it with parchment paper.
Prepare the crumb base: In a large bowl, whisk together the flour, oats, sugar, and salt. Add the cold, cubed butter and use your fingertips, a pastry blender, or two butter knives to rub the butter into the dry ingredients until it forms a sandy, crumbly texture with small clumps.
Add wet ingredients: Mix in the egg yolk and vanilla extract until the dough comes together and holds when pressed.
Form the crust: Scoop out ¾ cup of the dough and press it firmly into the prepared baking dish to create an even base. Chill the remaining dough in the fridge.
Bake the crust: Place the pan in the oven and bake for 15 minutes. Remove from the oven and let it cool slightly.
Add jam layer: Spread your chosen jam evenly over the warm crust.
Top with crumb: Sprinkle the chilled dough over the jam layer evenly.
Bake the bars: Return the dish to the oven and bake for 40–45 minutes, until the top is golden and the edges are lightly browned.
Cool and slice: Let the bars cool completely in the pan. Use the edges of the parchment paper to lift them out, then cut into squares or rectangles and serve.
