Why You’ll Love This Funfetti Pound Cake

  • It’s incredibly moist and buttery, with that classic pound cake texture.
  • The sprinkles add a pop of color and a fun, festive vibe to every bite.
  • It’s surprisingly simple to make, even for beginner bakers.
  • Perfect for birthdays, holidays, or just a sweet treat any day of the week!

Ingredients You’ll Need

  • Plugrà® Premium European Style Salted Butter: This butter makes a huge difference! Its higher fat content gives the pound cake an incredibly rich flavor and tender crumb. If you can’t find Plugrà, use another high-quality European-style salted butter.
  • Cake Flour: Cake flour is key for a super tender pound cake. It has a lower protein content than all-purpose flour. Don’t skip it!
  • All-Purpose Flour: We use a combination of cake and all-purpose flour to get the perfect balance of tenderness and structure.
  • Buttermilk: Buttermilk adds a lovely tang and helps keep the cake moist. If you don’t have buttermilk, you can make a DIY version by adding 1/2 tablespoon of lemon juice or white vinegar to 3 tablespoons of whole milk and letting it sit for 5-10 minutes until it curdles.
  • Rainbow Sprinkles: Use jimmie-style sprinkles for the best results – they tend to bleed less color into the batter than nonpareils.

How to Make Funfetti Pound Cake Step by Step

First things first, preheat your oven to 325 degrees F and get your 9×5-inch loaf pan ready by lining it with parchment paper. This parchment sling makes it super easy to lift your beautiful cake out once it’s baked. Trust me, it’s a game-changer!

Now for the batter! In your stand mixer, you’ll cream together the room-temperature butter and granulated sugar for a full five minutes. This step is crucial for incorporating air and getting that light, fluffy texture. Scrape down the bowl halfway through to make sure everything is evenly mixed. While that’s creaming, whisk together your eggs, egg yolks, buttermilk, vanilla, and salt in a separate bowl. This ensures everything is well combined before it goes into the butter mixture.

Here’s where the magic happens: slowly add the egg mixture to the butter, one dollop at a time. Let each addition fully incorporate and fluff up before adding the next. Don’t worry if it looks a little split – it’ll come back together. Finally, sift in your powdered sugar and baking powder, mix until smooth, and then gently fold in those colorful rainbow sprinkles. Remember, don’t overmix once the flour is in, or your cake might be tough. Bake it for about 60 minutes, or until a skewer comes out with just a few moist crumbs. Then, let it cool completely before glazing and enjoying!

Funfetti Pound Cake - step by step

My Top Tips for Success

  • Room Temperature Ingredients are Key: I always make sure my butter and eggs are at room temperature. This helps them emulsify better and creates a smoother, more uniform batter.
  • Don’t Skimp on Creaming Time: That 5 minutes of creaming butter and sugar is essential! It incorporates air, which contributes to the cake’s light texture.
  • Measure Flours Correctly: I always use a kitchen scale for flour, or the spoon and level method. Too much flour can make your cake dry.
  • Don’t Overmix: Once you add the dry ingredients, mix just until combined. Overmixing develops gluten, leading to a tough cake.
  • Cool Completely Before Glazing: Trust me on this one! If your cake is warm, the glaze will melt right off. Patience is a virtue here.
  • Use Good Quality Sprinkles: Jimmie-style sprinkles hold their color better than nonpareils, preventing your batter from turning a muddy color.

Common Mistakes to Avoid

  • Using Cold Ingredients: If your butter and eggs are cold, they won’t combine properly, leading to a lumpy batter and a dense cake.
  • Not Creaming Butter and Sugar Enough: This step builds the structure and lightness of the cake. If you rush it, your pound cake won’t be as tender.
  • Overmixing the Batter: After adding the flour, overmixing develops too much gluten, making the cake tough and chewy instead of tender.
  • Opening the Oven Door Too Early: Resist the urge to peek during the first 45 minutes of baking, as this can cause the cake to sink.
  • Glazing a Warm Cake: The glaze will simply melt and run off, creating a mess instead of a beautiful finish.

How to Store Funfetti Pound Cake

  • Countertop: Store the pound cake tightly wrapped in plastic wrap or in an airtight container at room temperature for up to 3-4 days.
  • Refrigerator: To extend freshness, store in an airtight container in the refrigerator for up to 1 week. Bring to room temperature before serving for best flavor.
  • Freezer: Wrap individual slices or the whole cooled cake tightly in plastic wrap, then in aluminum foil. Freeze for up to 3 months. Thaw overnight in the refrigerator or at room temperature.

Frequently Asked Questions

Can I use all-purpose flour instead of cake flour?

You can, but your cake will be a bit denser. Cake flour has a lower protein content, which gives pound cake its signature tender crumb. For best results, I recommend sticking to the recipe’s flour blend.

Why did my sprinkles bleed color into the batter?

This usually happens with nonpareil sprinkles, which have a thin coating that dissolves easily. For vibrant, un-bled sprinkles, use good quality jimmie-style sprinkles and fold them in gently at the very end of mixing.

My pound cake cracked on top, is that normal?

Yes, it’s completely normal for pound cakes to crack on top! This is a classic characteristic. It happens as the cake rises and the outer crust sets faster than the interior.

Can I make this pound cake in a different pan?

You can, but baking times will vary significantly. If using a different size pan, you’ll need to adjust the baking time and monitor for doneness with a skewer.

Can I make the glaze thicker or thinner?

Absolutely! For a thicker glaze, add less milk, or more powdered sugar. For a thinner glaze, gradually add more milk until you reach your desired consistency.

I genuinely hope this Funfetti Pound Cake brings a little bit of extra joy and color to your day, just like it does for me. It’s such a fun and delicious treat to share. If you make it, please let me know how it turns out!

Instructions

  1. Preheat your oven to 325 degrees F.

  5. Scrape the bowl halfway through mixing to ensure even creaming.
  6. Into a medium bowl, add the eggs, egg yolks, buttermilk, 1/2 teaspoon vanilla, and kosher salt.
  7. Whisk quickly to blend these ingredients together.

  15. Bake the cake for 60 minutes.

Notes

Ensure all cold ingredients like butter and eggs are at room temperature for a smooth batter.
Do not overmix the batter once the flour is added, as this can lead to a tough cake.
Always cool the pound cake completely before applying the glaze to prevent it from melting.
Use jimmie-style sprinkles for best results, as they tend to hold their color better during baking.
