Jennie’s Thoughts
Rhubarb desserts always remind me of spring. There is something so comforting about a warm fruit crisp bubbling away in the oven.

What I love most about this recipe is the contrast between the tart rhubarb and the sweet buttery crumble topping. The oats become perfectly crisp while the rhubarb softens into a jammy filling underneath.
If you’ve never baked with rhubarb before, this is one of the easiest and most delicious recipes to start with.

And if you’re anything like me, don’t forget the vanilla ice cream. The cold ice cream melting into the warm crisp is absolutely incredible.
