Preheat your oven to 350°F (175°C) and line a 9x9-inch (23x23 cm) baking pan with parchment paper, leaving some overhang for easy removal.
In a large mixing bowl, cream together the unsalted butter, granulated sugar, and brown sugar until light and fluffy. This will take about 2-3 minutes with a hand or stand mixer on medium speed.
Mix in the vanilla extract until fully incorporated.
In a separate bowl, whisk together the all-purpose flour, rolled oats, baking powder, and salt.
Gradually mix the dry ingredients into the wet ingredients until the dough is crumbly but holds together when pressed.
Set aside about 1 cup of the crumb mixture for the topping and press the remaining mixture evenly into the bottom of the prepared baking pan to form the crust.
Spread the jam evenly over the crust, leaving about 1/4-inch (0.6 cm) margin around the edges to prevent sticking.
Crumble the reserved dough mixture over the jam layer to form a crumb topping.
Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and the jam is bubbling slightly.
Allow the bars to cool completely in the pan on a wire rack before lifting them out and cutting them into 16 squares or rectangles.
