Preparation

• Preheat oven to 350 degrees F. Line an 8 by 8-inch baking dish with aluminum foil, leaving a 2-inch overhang of foil on two sides. Grease foil.
• In a large mixing bowl, whisk together flour, baking soda and salt. Stir in oats and brown sugar, and use clean fingertips as needed to break up brown sugar clumps.
• Add butter, and using fingertips, work butter into mixture until evenly moistened.
• Add 2 cups of the oat mixture to the prepared baking dish and press into an even layer.
• Spread raspberry jam into an even layer over oat layer, coming within ¼-inch of all edges. Sprinkle top evenly with remaining oat mixture, then slightly press into jam layer.
• Bake in preheated oven until golden brown, about 34 - 38 minutes.
• Remove from oven and allow to cool completely before cutting into squares. Store in an airtight container.
