Having a young daughter who is a princess-to-be means that everything is always rainbows, sprinkles, sparkles, and fairy tale inspired. She is a true girly-girl to her core! So I wanted to make a special cake inspired by her youthful and girly style. I combined that idea with one of my top favorite desserts to bake, the bundt cake, and twisted them together to come up with the ultimate pink dream of a cake! I made her a sugary, sweet Funfetti Bundt Cake filled and topped with pink buttercream frosting and decorated with colorful rainbow sprinkles! For this particular cake project, I am so glad I chose pink coloring for my frosting because the color really helps give it that extra girly flair for a really girly young lady.
I did run into a few learning curves when I first attempted this funfetti bundt cake though. I ended up having to make this cake 3 times because the cake and sprinkles inside kept sticking to the pan. Now I learned some time ago that the simple solution to removing cooked bundt cakes from their pan without sticking was just to coat the inside of the pan with shortening and flour and then to shake out the excess flour before pouring in the cake batter. However, it wasn’t quite that simple with this particular cake because of the sugary sprinkles. I finally figured out that the solution for the funfetti cake was to use more shortening in the pan and not to shake out the excess flour. You need that extra flour to keep the sprinkles from melting and sticking to the pan. As long as you keep that part in mind this will still be a fun and easy cake to make!
Equipment for Bundt Cake Success:
The first step of any successful baking project is to prepare yourself with the right tools for the job. For this funfetti bundt cake, you will need some usual baking equipment but with a couple of extra tools that you may not have thought to use before. Those special tools are what is needed to be able to easily fill and decorate the cake with buttercream frosting.
Bundt Cake Tools:
- Cooling rack
- Electric hand mixer
- Glass mixing bowls
- Bundt cake pan
- Blending whisk
- Apple Corer
- Piping bags
- Piping bag ties
Bright and Colorful Funfetti Bundt Cake Ingredients
After you have your bundt cake tools and equipment gathered up and ready, it is time to move on to rounding up the ingredients for this sugary sweet cake. To make this particular baking adventure a bit easier on myself I decided to use a store-bought buttercream frosting and just spruce it up at home for a better quality. For the absolute best-tasting cakes I usually like to go completely homemade and make my own Buttercream Frosting from scratch but sometimes there just is not enough time for all of that.
For Funfetti Bundt Cake:
- 3 Cups Cake flour or all-purpose flour – I much prefer using cake flour in my cake recipes because it makes such a wonderful difference in the final cake moisture and texture.
- ½ tsp Salt
- ½ tsp Baking powder
- 6 Eggs
- 1 tsp Vanilla extract
- 1 Cup Butter room temperature
- 2 Cups Sugar
- 1 Cup Sour cream
- ½ Cup Confetti rainbow sprinkles

Baking Up a Perfect Funfetti Bundt Cake
Now we can move on to the super-satisfying part of this baking journey: making and baking the magic! Overall this fancy cake is really easy and fun to make. And with the extra yummy filling the final result is just absolutely fabulous. Just make sure to read over all of the steps before beginning your cake-baking project at home to have a general idea of the different steps you will need to take for this particular cake. Also, keep in mind that there’s a bit more to the coating process for this specific recipe.
Mixing Up the Funfetti Cake Batter:
- First, preheat the oven to 350°F.
- In a medium-sized glass mixing bowl, mix together the cake flour, baking powder, and salt.
- Then, in a separate large mixing bowl, use the hand mixer to beat the butter and sugar together until light and pale in color.
- Next, use the blending whisk to whisk the eggs together in another separate bowl. Then, drop in the vanilla extract and whisk again.
- Then, add in the sour cream and mix well.
- Add the egg mixture, ½ at a time, into the large bowl with the butter/sugar mixture.
- Then, add in the dry ingredients ⅓ at a time into the large bowl with the wet ingredients, mixing well between each addition.
Coating the Bundt Cake Pan:
- Start by greasing the bundt cake pan with the vegetable shortening.
- Then, sprinkle the all-purpose flour over the entire inside of the bundt cake pan and roll the flour around to make sure the entire pan is thoroughly coated. Don’t shake out the excess flour!
- Next, pour the funfetti cake batter evenly into the bundt pan.
- Bake the funfetti bundt cake for 50-65 minutes, or until a toothpick inserted in the center of the cake comes out clean.
- Then, cool the cake for a full 10 minutes before removing it from the cake pan.
- Carefully transfer the cake from the pan onto the cooling wire rack. Cover the cake with a kitchen towel and let it cool again for 30-40 minutes.
- To make this baking project a little quicker on yourself, while the cake is cooling you can start getting the buttercream frosting ready.
- After the cake has cooled completely, flip the cake upside down onto the cutting board. Then, use an apple corer to punch 6 holes into the cake. Do not discard the pieces of cake that were punched out, you will need them for later.
Filling and Garnishing the Funfetti Cake:
- To prep the store-bought buttercream frosting, start by transferring it all into a large mixing bowl and mix on medium speed with the hand mixer for 2-3 minutes.
- Then, use a toothpick to add a small amount of pink food coloring to the frosting and mix until the color is combined evenly.
- Next, transfer ⅓ of the pink buttercream frosting into a pastry piping bag and close it off with a piping bag tie.
- Now, grab a pair of scissors and cut ½ inch from the tip of the piping bag. Pipe the buttercream frosting into the holes you punched out from the cake and then close them back with the cake cut-outs.
- Then, carefully flip the bundt cake onto a cake stand or a cake-sized serving plate.
- Spoon the rest of the buttercream frosting on top of the funfetti bundt cake and spread it until the cake is frosted completely.
- Finally, sprinkle the remaining confetti rainbow sprinkles generously over the top of the finished funfetti bundt cake.
