Apple Crisp Shortbread Bars combine a buttery shortbread base with a cinnamon-spiced apple filling and a crunchy oat topping. This easy fall dessert is perfect for families, potlucks, or cozy afternoons and is portable enough for lunchboxes.
Use cold butter for both the shortbread and topping for best texture. Thinly slice apples for even baking. Let bars cool completely before slicing for clean edges. For gluten-free, substitute flour with a 1:1 gluten-free blend. Add nuts or extra spices for variation. Bars can be stored at room temperature for 2 days, refrigerated for 5 days, or frozen for up to 2 months.
