- Stir the oats and brown sugar together in a medium bowl.
- Mix in the melted butter until clumps form.
- Heat the oven to 350°F.
- Grease a 9-inch square baking pan with 1 teaspoon of the canola oil.
- Whisk the flour, baking soda, salt, ginger, cinnamon, and cloves together in a medium bowl.
- In a large bowl, whisk the granulated sugar, remaining 1/3 cup canola oil, molasses, egg, and buttermilk until smooth.
- Add the dry ingredients to the wet ingredients and stir just until no dry flour remains.
- Spread the batter in the prepared pan.
- Scatter the crumble topping evenly over the batter.
- Bake at 350°F for 38 to 45 minutes, until a toothpick inserted in the center comes out with a few moist crumbs.
- Let the cake rest in the pan for 20 minutes before slicing.
Notes
For a tender cake, stir the batter just until no dry flour remains. Store covered in the refrigerator for up to 4 days; it can be frozen for up to 2 months. For a dairy-free variation, use dairy-free butter and dairy-free buttermilk.
