What is rhubarb crumble made of?

Rhubarb crumble bars typically consist of a buttery, crumbly topping and base made from flour, butter, sugar, and sometimes oats. The filling is made from chopped rhubarb, sugar, and sometimes other fruits or flavorings like ginger or vanilla.

How do you make rhubarb less tart in crumble?

To reduce the tartness of rhubarb in a crumble, use a generous amount of sugar in the filling. You can also combine rhubarb with sweeter fruits like strawberries or raspberries, or add a touch of vanilla extract to mellow the flavor.

What goes well with rhubarb crumble?

Rhubarb crumble pairs well with vanilla ice cream, whipped cream, custard, or a simple drizzle of heavy cream. The creamy sweetness complements the tartness of the rhubarb beautifully.

Why is my crumble topping not crunchy?

A crumble topping may not be crunchy if there's too much butter or not enough dry ingredients. Ensure you have the right ratio of flour, butter, and sugar. Chilling the crumble topping before baking can also help it crisp up better. Avoid over-crowding the topping as this can steam it, resulting in a soft topping.

How do you know when rhubarb crumble is done?

Rhubarb crumble bars are done when the topping is golden brown and the rhubarb filling is bubbling around the edges. A toothpick inserted into the crumble (avoiding only topping) should come out with moist crumbs, but not wet batter. The rhubarb should be tender when pierced with a fork.

Instructions

Preheat oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on two sides.
In a large bowl, whisk together flour, oats, brown sugar, baking soda, and salt.
Add cold, cubed butter to the dry ingredients. Use fingertips, a pastry cutter, or two forks to work the butter in until the mixture resembles coarse sand with some pea-sized clumps.
Reserve 1 1/2 cups of this mixture for the topping and set aside.
Press the remaining mixture firmly and evenly into the bottom of the prepared pan. Use the bottom of a measuring cup to compact it.
Bake the crust for 12-15 minutes, until edges are lightly golden. Remove from oven.
While crust bakes, make the filling. In a large bowl, toss chopped rhubarb with granulated sugar, cornstarch, vanilla, lemon zest, and lemon juice.
Spread the rhubarb filling evenly over the hot crust.
Sprinkle the reserved crumble topping evenly over the rhubarb. Do not press down.
Bake for 45-50 minutes, until topping is deeply golden and filling is bubbling vigorously at the edges.
Let the pan cool completely on a wire rack for about 2 hours.
Use the parchment paper to lift the entire block onto a cutting board. Slice into 18 bars with a sharp knife.

Notes

Use cold butter for the best crumbly texture. Do not skip the cornstarch, as it thickens the filling. Let bars cool completely before cutting for clean slices. Frozen rhubarb can be used without thawing; add a few extra baking minutes.
