preheat oven to 350. Place parchment paper in a 9x13 pan.
Assemble the crust. In a bowl, place room temperature butter. On top of butter place the sugar, vanilla and salt, flour and powdered sugar. With a fork, mix ingredients and cut butter into the mixture. It will not come together completely. To tell if it's ready to press into pan, take some of the mix and press it together in your palm. If it holds shape, it's ready.
Pour out crust crumbles and press evenly into the pan.
Place in preheated oven and bake for 12 minutes or until golden brown around the edges.
Remove from oven and immediately take jam and spread evenly over crust.
Assemble the topping. This can be done while the crust is cooking.
Melt butter on stovetop. While butter is melting, combine all other ingredients into a bowl. Drizzle melted butter over top and lightly toss together.
Sprinkle mixture evenly over jam.
Place back in oven, again at 350, for 15 minutes.
Removed and allow to cool completely. Cut into 2x2 squares and serve.
Keep at room temperature or in fridge for up to 3 days.
