Method
Preheat the Oven:
- Preheat the oven to 375°F (190°C).
- Grease a 9x9-inch baking pan or line it with parchment paper.
Prepare the Cake Batter:
- In a large mixing bowl, whisk together egg, sugar, milk, oil, and vanilla extract.
- Gradually mix in flour, baking powder, and salt until just combined (do not overmix).
Transfer to Baking Dish:
- Pour the batter into the prepared baking dish, spreading it evenly.
Make the Streusel Topping:
- In a small bowl, mix melted butter, brown sugar, cinnamon, and flour until crumbly.
- If using nuts, stir them into the mixture.
Assemble the Cake:
- Evenly sprinkle the streusel topping over the cake batter.
- Lightly press some of the topping into the batter to create pockets of cinnamon flavor.
Bake:
- Place in the oven and bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
Optional Icing:
- While the cake is baking, whisk together powdered sugar, milk, and vanilla extract for a simple glaze.
- Drizzle over the cake once slightly cooled.
Serve & Enjoy:
- Slice and serve warm with coffee, tea, or your favorite beverage.
