How to Make Classic Rhubarb Crumble Bars – moanaskitchen

Let’s make it together! Follow these simple, sensory-rich steps to create your very own Classic Rhubarb Crumble Bars:

Preheat Your Oven: Preheat your oven to 350°F (175°C). Line a 9×9 inch baking dish with parchment paper, leaving some overhang for easy removal later.
Prepare the Crust: In a large bowl, combine 1/2 cup sugar, 2 cups flour, baking powder, and salt. Add the cold butter cubes and mix with your fingertips or a pastry cutter until the mixture resembles coarse crumbs. Whisk the egg in a separate bowl, then add it to the dough mixture. Mix until combined.
Press and Bake: Press approximately two-thirds of the dough into the bottom of the prepared baking dish. Bake for about 15 minutes, until golden and slightly firm.
Make the Rhubarb Filling: In a medium bowl, toss the sliced rhubarb with 1/2 cup sugar, lemon zest, lemon juice, vanilla extract, and cornstarch until well coated.
Combine: Once the crust is done, remove it from the oven and pour the rhubarb mixture over the crust, spreading it evenly.
Prepare the Topping: In another bowl, mix the old-fashioned oats, 1/2 cup sugar, vanilla sugar,ground cinnamon, and the melted butter together until crumbly. Sprinkle this mixture evenly over the rhubarb filling.
Final Bake: Return the baking dish to the oven and bake for an additional 25-30 minutes, or until the topping is golden and the filling is bubbling.
Cool and Slice: Allow the bars to cool completely in the pan before using the parchment to lift them out. Slice into squares and serve.

Variations & Creative Twists

Feel free to get creative with these delectable bars! Here are a few fun variations to try:

Berry Twist: Add 1 cup of fresh strawberries or blueberries for a delicious combined filling that enhances the flavors.
Nutty Delight: Sprinkle some chopped walnuts or almonds into the crumb topping for an extra crunch and nutty flavor.
Zesty Infusion: Experiment with citrus by adding orange zest along with the lemon for an entirely new twist!
Seasonal Switch-Up: Swap rhubarb for apples or peaches, adjusting the sugar according to your fruit’s sweetness for a delightful change.
