1/2 cup sugar
2 cups all-purpose flour
1 tbsp baking powder
2/3 cup butter (cold and cut into 1/2-inch cubes)
1/2 teaspoon salt
1 egg
5 stalks rhubarb (sliced into 1/2-inch thick pieces)
1/2 cup sugar
1 lemon (freshly zested and juiced)

2 1/2 tsp cornstarch

1/2 cup sugar
1 tsp vanilla sugar
1/2 teaspoon ground cinnamon
1/2 cup butter (melted and cooled slightly)

How to Make Classic Rhubarb Crumble Bars – moanaskitchen

Preheat Your Oven: Begin by preheating your oven to 350°F (175°C). Line a 9×13 inch baking dish with parchment paper, allowing some overhang for easy removal later.
Prepare the Crust: In a large mixing bowl, combine 1/2 cup sugar, 2 cups of flour, baking powder, and salt. Add the cold butter cubes to the mixture and use a pastry cutter or your hands to mix until the texture resembles coarse crumbs. Beat the egg lightly and then stir it into the flour mixture until just combined.
Press the Crust into the Pan: Take about two-thirds of the crumb mixture and press it evenly into the bottom of the prepared baking dish. This will be the base of your delicious bars.
Mix the Filling: In a separate bowl, combine the sliced rhubarb, 1/2 cup sugar, lemon zest, lemon juice, vanilla extract, and cornstarch. Toss gently until the rhubarb is well coated with the mixture.
Spread the Filling: Pour the rhubarb mixture over your pressed crust, spreading it evenly.
Prepare the Topping: In the same bowl you used for the crust, add old-fashioned oats, 1/2 cup sugar, vanilla sugar, ground cinnamon, and melted butter. Mix until crumbly.
Top the Filling: Sprinkle the oat mixture evenly over the rhubarb filling, covering it generously.
Bake: Place the baking dish in the oven and bake for about 35-40 minutes or until the top is golden brown and the filling is bubbling.
Cool and Slice: Allow the bars to cool in the baking dish for at least 15 minutes before lifting them out using the parchment overhang. Let them cool completely on a wire rack before slicing into squares.

Variations & Creative Twists

Berry Burst: Add a handful of fresh blueberries or strawberries to the rhubarb filling for a delightful fruity twist.
Nutty Crunch: Stir in chopped pecans or walnuts into the crumble topping for extra texture and a nutty flavor.
Zesty Orange: Swap lemon for fresh orange zest and juice for an enhanced citrus flavor that pairs beautifully with the rhubarb.
Spiced Delight: Add a pinch of nutmeg to the crumble for a warm, aromatic touch that makes these bars even more comforting.
