Step-by-Step Baking Guide Sweet Potato Coffee Cake
Step 1: Prepare the Sweet Potatoes
Roast or boil 2 medium sweet potatoes until tender. Peel and mash until smooth. Let them cool before adding to the batter. Roasting enhances the flavor, giving it that caramelized sweetness similar to sweet potato chocolate cake.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together flour, baking powder, baking soda, salt, and spices. Set aside.
Step 3: Cream Butter and Sugar

In a large mixing bowl, beat the softened butter and brown sugar until light and fluffy about 2–3 minutes. Add eggs one at a time, mixing well. Then, add mashed sweet potatoes and vanilla extract.
Step 4: Combine Wet and Dry
Add the dry ingredients to the wet mixture alternately with sour cream (or Greek yogurt). Mix until just combined don’t overmix, or the cake may lose its tender texture.
Step 5: Make the Streusel
Combine brown sugar, flour, cinnamon, and cold butter. Use a fork or pastry cutter to mix until crumbly. Stir in chopped pecans if you want that coffee bundt cake crunch.

Step 6: Assemble
Pour half the batter into a greased 9×9-inch pan. Sprinkle a layer of streusel, then top with remaining batter. Finish with another layer of streusel on top.
Step 7: Bake
Bake at 350°F (175°C) for 40–45 minutes, or until a toothpick inserted in the center comes out clean. The top should be golden brown and fragrant.
Step 8: Cool and Glaze
Let the cake cool for 20 minutes before drizzling with the glaze. The slight warmth will help it soak in beautifully, giving it that glossy coffee-shop finish.
