Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
- In a mixing bowl, whisk together the mashed sweet potatoes, granulated sugar, brown sugar, eggs, vegetable oil, and vanilla extract until smooth.
- Sift the all-purpose flour, baking powder, baking soda, salt, ground cinnamon, nutmeg, and ginger in a separate bowl. Gradually incorporate the dry mixture into the wet ingredients until just combined.
- Stir in the buttermilk until the batter is smooth. Pour into the prepared baking dish and smooth the top.
- Mix together melted butter, brown sugar, flour, and cinnamon in a small bowl until crumbly. Drop spoonfuls over the batter and swirl with a knife.
- Bake for 35–40 minutes until a toothpick comes out clean.
- While baking, whisk together powdered sugar, milk, and vanilla extract for the glaze until smooth.
- After cooling for 10–15 minutes, drizzle the glaze over the cake and let cool completely before serving.

Notes
Ensure ingredients are at room temperature for an even batter. Use fresh sweet potatoes for best flavor and avoid overmixing after adding flour.
