This recipe comes together in a few simple stages: prepping the pan, mixing dry ingredients, whisking wet ingredients, combining them gently, baking to perfection, and finishing with a sweet glaze. Follow each step for a tender, flavorful cake that’s sure to impress.
1. Preheat your oven to 350°F (175°C). Grease and flour a 9x13-inch baking dish, tapping out any excess flour to ensure an even, nonstick surface.
2. In a large mixing bowl, combine the flour, granulated sugar, brown sugar, baking powder, ground cinnamon, and salt. Mix well so that every bit of the dry blend is evenly incorporated and no clumps remain.
3. In a separate bowl, beat the eggs until slightly frothy. Add the sweet potato puree, vegetable oil, sour cream, and vanilla extract. Whisk these together until the mixture is completely smooth, with no streaks of puree or egg whites.
4. Gradually add the wet ingredients to the dry ingredients, using a gentle stirring motion until just combined. Be careful not to overmix, as that can tighten the gluten and yield a tougher crumb.
5. Pour the batter into the prepared baking dish, using a spatula to spread it evenly into the corners for consistent thickness across the pan.
6. Bake for 45–50 minutes, or until a toothpick inserted into the center comes out clean. The top should be a light golden brown and spring back slightly to the touch.
7. While the cake is baking, prepare the glaze: In a small bowl, stir together the powdered sugar, milk, honey, and vanilla extract until smooth and lump-free.
8. Once the cake is finished and has cooled slightly, drizzle the glaze evenly over the top. Allow the glaze to set for a few minutes before slicing into that first luxurious piece.
