Step‑by‑Step Instructions
- Preheat your oven to 350°F (175°C) and line an 8 x 8-inch baking pan with parchment paper.
- In a mixing bowl, combine melted butter, light brown sugar, all-purpose flour, ground cinnamon, and a pinch of salt to make the crumb topping.
- In a stand mixer, cream together unsalted butter, vegetable oil, and granulated sugar until fluffy. Add eggs one at a time and mix in vanilla extract.
- Whisk together flour, baking powder, baking soda, and salt. Gradually add to the wet ingredients, alternating with sour cream and milk.
- Pour the batter into the baking pan and spread evenly. Sprinkle the crumb topping over the batter.
- Bake for approximately 35 minutes until golden brown and a toothpick comes out clean.
- Cool completely in the pan on a wire rack, then dust with powdered sugar before serving.

Notes
Ensure butter is creamed well for rich texture and avoid overmixing to keep the cake tender. Use fresh ingredients for best flavor.
