Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). A proper preheated oven ensures even baking, which is essential for achieving that perfect crust on your rhubarb crisp.
Step 2: Prepare the Rhubarb
In a large bowl, combine the chopped rhubarb, granulated sugar, cornstarch, cinnamon, and vanilla extract. Mix until the rhubarb is well-coated. This step helps to release the lovely juices from the rhubarb while sweetening it.
Step 3: Create the Topping
In another bowl, mix the rolled oats, flour, brown sugar, melted butter, and a pinch of salt. Your mixture should resemble coarse crumbs. This texture is essential for that delightful topping crunch!
Step 4: Assemble the Crisp
Spread the rhubarb mixture evenly at the bottom of a greased baking dish. Then, sprinkle the oat mixture generously over the rhubarb. An even topping guarantees a balanced flavor in every bite.
Step 5: Bake
Place the dish in your preheated oven and bake for about 40 minutes, or until the topping is golden brown and the rhubarb is bubbling. The aroma wafting through your kitchen will bring back lovely memories!
