We’re still celebrating The Speckled Palate’s sixth birthday today, and what better way to do that than by republishing one of my first recipes ever?

These Sour Cream Funfetti Cupcakes are just as good today as they were six years ago.

But I’m going to go out on a limb and guess most of y’all weren’t here to check ’em out six years ago, so I decided to give the post a bit of a facelift.

    That’s how we roll for birthdays, y’all.

    This recipe was inspired by a family friend’s wedding cake.

    While I didn’t attend the wedding, I heard about their cake. Specifically, a FUNFETTI layer.

    How cool is that?!?

    And why the heck didn’t we request that for our wedding cake?

    My stomach growled when my mother told me about the cake, and promptly after I hung up, my stomach requested something funfetti.

    However, I didn’t want to go to the store to get the boxed mix. Instead, I dug around in my pantry and discovered I had ingredients to make funfetti. Specifically, sprinkles. Because those are essential in funfetti.

    Funny story: The sprinkles I found in my kitchen that day? They were from my bachelorette party. And that’s all I’m gonna say about ’em. 😉

    The one problem I ran into: I didn’t have cream cheese for the icing, and cream cheese icing is my favorite.

    So I did some digging in the fridge and found some sour cream.

    Similar enough, right?


    Yes, I know. It sounds bizarre, but the sour cream balances out the sweetness of the cupcakes and powdered sugar here, and it works like a charm!

    These Sour Cream Funfetti Cupcakes are fluffy and moist. They’re not saccharine sweet, and neither is the frosting.

    Which is exactly what I love in a baked good.

    Making funfetti from scratch? Ain’t a thing. And if you’ve got the ingredients, they’re super easy to pull together!

    Now who wants a cupcake of their own?

    I wish I could share mine with each and every one of you — this is technically a birthday party — but alas.

    Sour Cream Funfetti Cupcakes

    Let’s bake today… and use sour cream to make these homemade Funfetti Cupcakes even more decadent! Instead of using the traditional boxed mix, we’ll cream together butter, sour cream, sugar, eggs and pure vanilla extract then add unbleached all-purpose flour, baking powder, milk and rainbow sprinkles to the batter. Dollop them into a cupcake tin before baking for 20 minutes. Once cooled, we’ll top them with tart Sour Cream Icing! These cupcakes are a sweet recipe for the weekend baker.

    Make the Cupcakes

    • Preheat oven to 350°F. Line a cupcake pan with cupcake liners, and spritz with nonstick cooking spray. Set aside.
    • In a large glass bowl, cream the sour cream, butter and sugar together.
    • Once the sour cream, butter and sugar are a smooth consistency, add the two eggs and the vanilla extract, mixing thoroughly.
    • Pour in the milk, and gently stir into the other wet ingredients until smooth.
    • In another bowl, sift together the flour, baking powder and salt. 
    • Add the dry ingredients to the wet ingredients, stirring until just combined.
    • Stir the rainbow sprinkles into the batter, careful not to overmix.
    • Dollop the batter into the prepared cupcake liners. Fill ¾ of the way full with a cookie scoop. 
    • Bake the cupcakes for 22-28 minutes, or until tops are light brown and a toothpick comes out clean.

    Make the Sour Cream Frosting

    • While the cupcakes bake, measure out the sour cream, powdered sugar, vanilla and salt into a glass mixing bowl.
    • Using a hand mixer, whip the icing until combined, smooth and shiny.
    • When the cupcakes have cooled, decorate with the frosting, and enjoy!

    1. Oooh, yummy! Love the new blog! Where did the name of it come from? It’s super adorable 🙂

      1. Thanks so much, Angela!

        The name actually was inspired by Lucy, our pup. Her palate is pink and black and is speckled, and we’ve laughed about this for years. So when it came time to figure out a name, I was drawn to The Speckled Palate… mostly because of her and partially because the foods we enjoy and cook are all over the board.

    2. I think I’m really going to love this new blog of yours. 😀

      I’m totally a cupcake girl. Not only do I love eating them, but I’ve become “famous” for making them in my family. I’m just starting to branch out from boxed mixes (I know, I know), so I’m always on the look-out for easy, from-scratch recipes. Thanks for sharing this one!

    3. Yum! I made homemade funfetti cupcakes for my birthday but they were on the dry/dense side. I need to give these a go because sour cream makes everything better. (Loving the new blog!)

    4. I make fun of my friends who use boxed mixes. These sound fabulous and I have some sprinkles in my pantry that need to be used. Fantastic new blog, dear!

    5. I just scrolled through all of your posts to show my husband your beautiful photos- we had a nice conversation about your talent. Also, Funfetti is my favorite.

    6. Looks so delicious, i love cakes made with sour cream! and i love funfetti, so really, this is win-win 🙂

    7. I am REALLY intrigued by using sour cream in this. I’ve also heard a can of Sprite works too to avoid the oil. I will have to definitely try this now

    8. Is there anything more festive than a funfetti cupcake? They are just so fun! I bet the sour cream makes the cake perfect!

      1. I’m with you, Dorothy. I don’t think there is anything more festive than funfetti. And the sour cream is SUCH a nice touch to the cake and icing – we’re big fans!

    9. These cupcakes look adorable and so yummy! I’m sure the sour cream works even better than the cream cheese to balance the sweetness!

    10. I think it’s so sweet that you were inspired to make these from a friend’s wedding. I have definitely used sour cream for baking but never for frosting so I will definitely try this! When I do, I will be sure to give you full credit. 🙂
