1cup2 sticks, or 16 Tablespoons unsalted butter, at room temperature
2/3cupsmooth peanut butterI like Jif
3cupsall purpose flour
8 - 9ozgood quality jamI used wild boysenberry
Set the oven to 350F
Spray a 9x9 square baking pan with baking spray, and, if you like, line it with a piece of parchment paper with long ends so you can lift out the baked squares for easier cutting.
Cream the butter and sugar together, along with the peanut butter, until everything is well combined and creamy. Beat in the salt and vanilla.
Gradually mix in the flour until it is completely blended in and the dough is crumbly. Don't over-mix it.
Press about 2/3 of the dough onto the bottom of the pan, covering the entire surface, and patting it gently down so it is evenly distributed. I like to use the back of a metal measuring cup to tamp the dough down and lightly flatten it.
Spread the jam evenly over the surface of the dough. It's fine if the jam isn't completely covered.
Crumble the remaining dough over the top of the jam, using your fingertips to break up the dough into large crumbles.
Bake for about 45 minutes, until lightly golden.
Let cool slightly before cutting.
