Preheat the oven to 350 F. Drain and rinse the beans very well. Blend everything except the chips and berries until completely smooth in a food processor. (The texture is best in a food processor, but a blender can technically work if you stop occasionally to stir contents with a spoon and ensure even blending.) Either stir in the white chocolate chips now or sprinkle on top before baking. Smooth batter into a greased or parchment lined eight inch pan. Press raspberries into the top. Bake 30 minutes. The blondies will look a little underdone when you take them out. They firm up while cooling.View Nutrition Facts
