Step 1

Preheat your oven to 350°F (175°C) and lightly grease a 9x13-inch baking dish or line it with parchment paper.

Step 4

Pour the wet ingredients into the dry ingredients and stir until just combined. Avoid overmixing.

Fold in the 2 cups of diced fresh rhubarb gently to ensure even distribution in the batter.

To make the crumble topping, mix 0.5 cup of melted butter, 0.5 cup of brown sugar, 0.5 cup of all-purpose flour, and 0.5 teaspoon of ground cinnamon in a small bowl until crumbly.

Step 8

Sprinkle the crumble topping evenly over the batter.
