Plus, it’s versatile enough to dress up for special occasions or keep casual for cozy Sundays.

Ingredients

Before we dive into the kitchen, let’s gather what we need:

  • 1 cup mashed sweet potatoes (about 2 medium sweet potatoes)
  • ½ cup unsalted butter, softened
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 ½ cups all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon nutmeg
  • ½ cup buttermilk

Steps

Step 1: Preheat Your Oven

First things first—preheat your oven to 350°F (175°C). While that’s warming up, you can prep your sweet potatoes. If you haven’t already, peel and boil them until tender, then mash away. This little step will fill your kitchen with that nostalgic aroma we all love.

Step 2: Cream That Butter!

Next, in a large mixing bowl, beat the softened butter and sugar together until creamy and smooth. This is where the fun begins! You might want to imagine you’re in an epic baking competition as you stir—though, let’s be real; there’s no shame in wearing your favorite fuzzy slippers while doing it!

Step 3: Add the Eggs and Vanilla

Crack those eggs into the mix and pour in the vanilla extract. Beat until they’re fully incorporated. I always like to take a moment to appreciate the mixture at this stage—it’s beautiful!

Step 4: Combine Dry Ingredients

In a separate bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg. This spice mix is what will make your taste buds dance! Slowly add the dry ingredients to the wet ingredients, alternating with buttermilk. It gets a little thick, so don’t be shy when mixing it all together!

Step 5: Sweet Potato Magic

Now, fold in your mashed sweet potatoes. This is where the magic happens! The sweet potatoes will add a lovely moisture and a subtle sweetness that is absolutely divine.

Step 6: Bake, Baby, Bake!

Pour your batter into a greased 9×13 inch baking pan. Pop it in the preheated oven and let it bake for about 30-35 minutes or until a toothpick comes out clean. The anticipation is real, my friends!

Step 7: Cool and Serve

Once it’s out of the oven, let it cool for a bit—if you can! Serve it as is or drizzle a little glaze (a simple mix of powdered sugar and milk) on top for some extra flair. I won’t judge if you sneak a slice before it cools down completely—some things are just too good to resist!

Cooking Tips for Success

  • Sweet Potato Shortcut: Feel free to use canned sweet potatoes if you’re short on time. Just make sure to drain them well before mashing!
  • Customize Your Spices: If nutmeg isn’t your favorite, feel free to swap it out for something else—ginger can be an excellent choice for an extra kick!
  • Don’t Skimp on the Butter: Seriously, this is a butter cake, and butter makes everything better—just don’t tell your doctor!

FAQs

Can I substitute butter with oil?
You can, but the rich flavor may not be as pronounced. Consider using a butter-flavored oil for a close match!

How can I store leftovers?
Store your cake in an airtight container at room temperature for up to 4 days. Just try to resist the urge to devour it all in one sitting—if you can!

Can I freeze this cake?
Absolutely! Wrap it well and freeze for up to 3 months. Just be prepared for everyone to ask for the recipe once they taste that deliciousness!

It’s amazing how a simple recipe can carry so much love and nostalgia, isn’t it? Grandma’s Famous Sweet Potato Butter Cake is more than just a dessert; it’s a slice of family tradition, a ticket to memory lane, and a reason to gather around the table. So grab your apron, channel your inner baker, and let’s keep the sweet traditions alive one slice at a time!
