1 cup Brown Sugar (213g)
1 ½ sticks (¾ cup) butter, softened (170g)
1 teaspoon vanilla
1 ½ cups seedless blackberry or red raspberry jam
Preheat the oven to 350 degrees F. Coat a 9-by-13-inch dish with cooking spray.
Mix the flour, oats, brown sugar, butter, and vanilla together.
Spread half the oat mixture into the pan. Spread with jam. Top with the other half of the oat mixture by gently pressing in.
