Description

A nostalgic, moist butter cake infused with real mashed sweet potatoes and warm spices, perfect for cozy gatherings and teatime treats.


Ingredients

  • 1 cup mashed sweet potatoes (cooked and cooled)
  • 1 cup unsalted butter, softened
  • 2 cups granulated sugar
  • 4 large eggs
  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 teaspoon ground cinnamon
  • ½ teaspoon ground nutmeg

Instructions

  1. Preheat the oven to 350 °F (175 °C). Grease and flour a 9×13‑inch baking pan.
  2. Cream the softened butter and sugar in a large bowl until light and fluffy.
  3. Beat in the eggs one at a time, scraping down the sides between each addition.
  4. Stir in the mashed sweet potatoes until evenly combined.
  5. In a separate bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
  6. Gradually add the dry ingredients to the wet mixture, mixing until just combined.
  7. Pour the batter into the prepared pan and smooth the top.
  8. Bake for 35–45 minutes, or until a toothpick inserted in the center comes out clean.
  9. Cool on a wire rack for 10 minutes, then slice and serve warm or at room temperature.

Notes

  • Use freshly baked or microwaved sweet potatoes for best texture and flavor.
  • Optional additions: ground cloves, ginger, or chopped nuts for variation.
  • Add a powdered sugar icing drizzle for extra sweetness.
  • Wrap leftovers tightly and store at room temperature for 2 days or refrigerate for up to 5 days.
  • Can be frozen for up to 3 months if well wrapped.
