Here’s what you will need:
1 1/2 cups cake flour
2 teaspoons baking powder
1/2 teaspoon salt
3/4 cup granulated sugar
1/2 cup vegetable oil
1 teaspoon vanilla
1/2 cup buttermilk
Reddi-wip for garnish
3/4 cup cake flour
1/2 cup granulated sugar
1/2 cup brown sugar
1 teaspoon cinnamon
Pinch of salt
4 tablespoons unsalted butter, melted
Begin by preheating your oven to 350 degrees F. Spray 12 mini (4 ounces) mason jars with nonstick flour-added cooking spray.
In a medium bowl, whisk together the cake flour, baking powder, and salt. Set aside.
In a large bowl, stir together the granulated sugar, vegetable oil, egg, vanilla, and buttermilk. Then slowly stir in the dry ingredients that you sat aside earlier.
Evenly divide the batter among the 12 prepared mini mason jars.
Next, prepare the crumb topping. In another bowl, whisk together the cake flour, granulated sugar, brown sugar, cinnamon, and salt. Slowly add the melted butter and stir until large and small clumps form. Spread equal portions of the crumb mixture on the tops of the batter in the jars.
Place the prepared mason jars on a baking sheet. Bake for 25-30 minutes or until a toothpick inserted near the center comes out clean. Allow to cool.
Before sharing, top with a whoosh of Reddi-wip.
