This is our favorite bar cookie. We've tried many types of fruit, and apricot is our favorite. To make a breakfast oatmeal bar, I double everything except the sugar and jam, which makes a bar that is less sweet.
For a neat taste mix two different preserves strawberry. After trying these bars many different ways, this is the modified version we liked best: Combine all dry ingredients first, then cut in butter with 2 knives as for pie dough. Press with fingers to form a solid mass. Use seedless fruit only preserves for filling. Bake in an 8X8-inch pan lined with buttered foil. Increase baking time by 5 minutes. Serve with vanilla ice cream. This is our personal favorite, but any way you make them, they're great!
Easy Skinny Strawberry Oatmeal Bars
I really think this recipe works better if you make it in an 8 or 9 inch square pan. If you want to use a 9x13 pan you really need to double the recipe. I doubled it and added 2T. milk and 2t. vanilla as suggested by another reviewer. I cooked 1C. dates, chopped, in 2C. water until thickened and used this as the fruit topping. Sprinkled cinnamon and ground cloves over it and baked as directed. Really great tasting, healthy snack for my family... not too much refined sugar and lots of fiber.
