This buttery and delicious Funfetti Pound Cake is a twist on my favorite pound cake, but with sprinkles and lots of color! 

Funfetti simply means you get to put lots of colorful sprinkles into the cake batter, which makes for a cake that is sweet to eat AND to look at! This is an especially great cake for parties although I can’t resist throwing sprinkles into our pound cake batter whenever I have some on hand. The buttery pound cake has a fine crumb, it is very moist, and has a hint of lemon and vanilla flavor. 

 

The cake is delicious just as it is, but today I decided to add a buttercream rainbow to go along with our cheerful funfetti theme.

Working with buttercream may seem intimidating at first, but once you get the hang of it, it is a lot of fun. There are so many exciting ways to be creative with it using different piping tips and designs.

 

How to Make a Funfetti Pound Cake

You can find the full, printable recipe at the bottom of this post. Here is a quick look at our steps.

 

• After pre-heating the oven, grease and flour a bundt pan and lower your oven rack to the next to lowest position.

 

• In a separate bowl whisk the flour, salt, and baking powder to combine, set aside for later.

 

• Cream the softened butter (If using a stand mixer, use the paddle attachment) on medium speed until smooth. Then, gradually add the sugar. Beat on medium speed until light and fluffy 3 to 5 minutes.

 

• Add the eggs one at a time blending after each to incorporate.

 

• Add the vanilla extract and lemon extract to the cup of milk. (By the way, lemon extract is optional but if gives just a hint of lemon flavor). Add the flour mixture alternately with the milk mixture to the butter, sugar, egg mixture. Begin and end with the dry ingredients (I do three additions of dry ingredients and two additions of wet.) Mix just until combined– be careful not to overmix!

 

•  The batter will be fairly thick. Next, the funfetti magic happens! Fold in about a cup of rainbow colored jimmies into the cake batter, and then scoop into your prepared bundt pan. I’ve found that the rainbow jimmies tend to bleed less than other sprinkles.

 

 

• Bake at 350 degrees F if using a light pan, bake a 325 if baking in a dark pan. It will be done in about 1 hour to 1 hour 10 minutes (or until the cake springs back when lightly touched and toothpick comes out clean or with just a few crumbs attached).
  

  

 

Decorating the Cake with a Buttercream Rainbow

I cooled my pound cake (still in the pan) for about ten minutes or so before flipping it out onto the cake pedestal. While it continued to cool, I made my vanilla buttercream frosting and divided it into different cups, tinting each a different color of the rainbow, and saving some extra for the white clouds.

Fit your piping bags with whatever piping tips you like. I used star 21 tips for all of my colors, piping shells for some and stars for others. For the clouds, I piped them with a tip 12, although you could also just snip the end of a piping bag for those. I love how it came out! This kind of easy buttercream piping is so fun to do and makes our funfetti pound cake even cuter and more colorful, which I love!

To pipe a buttercream shell, hold the piping bag (fitted with a star tip 21) at a 45 degree angle, slightly squeeze the bag, lift up lightly and come back down again before releasing the pressure. Repeat to create rows. You could also just create simple, colorful stars instead with a star tip (holding the piping bag vertically).

 

 

The puffy clouds are piped with a disposable piping bag with the tip snipped away.
