Easy Rhubarb Crumble Bars Ingredients For the Rhubarb Filling • Rhubarb – provides the signature tartness, essential for these Easy Rhubarb Crumble Bars. Substitute with strawberries for a seasonal twist. • White Sugar – sweetens the filling to balance the tart rhubarb; granulated or caster sugar works well. • Green Apple (grated) – adds a hint of natural sweetness and helps thicken the filling; can be omitted if needed. • Lemon Juice – brightens the flavors; optional for extra acidity that enhances the filling. • Water – helps cook down the rhubarb mixture to a jam-like consistency. For the Shortbread Base and Topping • All-Purpose Flour – forms the heart of the buttery crust and crumb; avoid bread flour for tenderness. • Sea Salt – enhances the overall flavor of the dough; a small yet essential ingredient for balance. • Unsalted Butter – brings richness and moisture; make sure it’s at room temperature for easy mixing. • Egg – binds the dough for structure; can be omitted for a vegan version but will require adjustments. • Vanilla Extract – infuses the crust with warm flavor; opt for pure extract for the best results. For the Crumble Topping (Optional) • Sliced Almonds/Rolled Oats – add delightful texture and additional flavor to the topping; feel free to leave out for simplicity. Step‑by‑Step Instructions for Easy Rhubarb Crumble Bars Step 1: Prepare the Rhubarb Filling Start by chopping fresh rhubarb into small pieces and add it to a medium pot along with sugar, grated apple, lemon juice, and water. Cook this mixture over medium heat until it reaches a boil. Once boiling, reduce the heat to low and stir frequently for about 20–30 minutes until the mixture thickens to a jam-like consistency. Let it cool completely before using it for assembling the Easy Rhubarb Crumble Bars. Step 2: Make the Shortbread Dough In a large mixing bowl, combine all-purpose flour, sugar, and sea salt. Incorporate room-temperature unsalted butter, egg, and vanilla extract into the dry ingredients using your hands or a fork, blending until a soft dough forms. Once combined, divide the dough into two parts, reserving three-quarters for the base and keeping one-quarter aside for topping the Easy Rhubarb Crumble Bars later. Step 3: Assemble and Bake Preheat your oven to 350°F (180°C) and prepare a 9×9 inch baking pan by greasing or lining it with parchment paper. Press the larger portion of dough evenly into the bottom of the pan to create a solid base. Afterward, spread the cooled rhubarb filling uniformly over the shortbread base, ensuring every corner is covered before crumbling the reserved dough on top to create a lumpy topping. Step 4: Baking Time Place the assembled Easy Rhubarb Crumble Bars into the preheated oven and bake for 35-40 minutes. Keep an eye on the crumble topping until it turns golden brown; this will indicate your bars are ready. Once done, remove from the oven and allow them to cool in the pan for at least 15 minutes before transferring to a wire rack to cool completely before cutting into squares.
