To make an easy snack of fruit bars, combine 1 1/2 cups of flour with 1 1/2 cups of old-fashioned oats, 1/2 cup of brown sugar, and 1/2 teaspoon of salt. Add 3/4 cup of cubed butter with 2 tablespoons of cold water. Stir for 30 seconds. Roll the dough into a baking dish, over parchment paper, and spread with the desired fruit preserve. Bake for 350 degrees Fahrenheit for 45 minutes. Allow the dish to cool before slicing.
Another popular fruit bar favorite is lemon squares. Prepare to bake these fruit bars by preheating the oven to 350 degrees Fahrenheit. Combine 1 cup of softened butter with 2 cups of all-purpose flour and 1/2 cup of white sugar. Stir into a crumble, and press this mixture into the bottom of a baking dish. Bake for 15 to 20 minutes until it is firm and golden brown.
Whisk together 1 1/2 cups of white sugar and 1/4 cup of flour. Then, add in 4 eggs and the fresh-squeezed juice from 2 lemons. Pour this mixture over the baked crust, and bake for an additional 20 minutes until the fruit topping is bubbling. Allow the bars to cool and firm up before cutting into identical 2-inch squares.
