No birthday is required in order to enjoy this best ever Funfetti Cake that starts with a boxed cake mix!
Sometimes we just need some colorful sprinkles in our life, am I right? Especially right now, with hard things happening in the world, I’m trying to look for the positive and happy. Funfetti Cake is one of those things!
My son turned ten last week! Where has the time gone? He’s such a kind brother and a smart, fun-loving, talented kid. We’re so glad he’s a part of our family! We celebrated at home in a big way! I asked him what he’d like me to make for dinner and it was Pizza Rolls. I asked him to choose what kind of cake and ice cream he’d like as well. I thought for sure he’d pick our favorite layered chocolate mint cake, but he surprised me and asked for a Funfetti Cake! I was so glad. In this gloomy time, we need a little extra happy in our day!
I happened to have a boxed white cake mix in my cupboard, so I decided to doctor it up to make it taste homemade, but without all the work!
I love a tender cake crumb and the buttermilk in this recipe really helps achieve this! The homemade vanilla buttercream frosting really takes it to the next level! It’s not short on sprinkles, either! Sprinkles in the cake batter plus sprinkles on top of the frosting really make this cake cheery and yummy!
Even if it’s not your birthday or someone’s birthday you know, any day is a great day for Funfetti Cake! This cake comes together so quickly and simply, starting with a boxed white cake mix as the base, yet tastes like you made it from scratch!
The Best Funfetti Cake Starting with a Boxed Mix
- 15.25 oz Classic White Cake Mix my favorite is Duncan Hines
- 3/4 cup buttermilk make your own by adding just enough white vinegar or lemon juice to cover the bottom of the 3/4 measuring cup, then filling the rest with milk; let it sit for a few minutes to turn sour
- 3 large eggs
- 1/2 c. butter melted
- 1 tsp. pure vanilla extract
- 1/2 c. colorful jimmies
- 1/2 c. butter softened
- 3 1/2 c. powdered sugar
- 1 tsp. pure vanilla extract
- Approximately 4 Tbsp. milk just enough for thinning; add it slowly
- Colorful jimmies for garnish
- Preheat the oven to 350 degrees Fahrenheit and grease a 9"x13" metal cake pan.
- In the bowl of an electric mixer, mix white cake mix, buttermilk, eggs, melted butter, and vanilla. Add sprinkles and quickly mix just until incorporated.
- Spread batter evenly into prepared pan.
- Bake for approximately 20-22 minutes, or just until a toothpick inserted into the center comes out clean. Don't over bake.
- Allow the cake to cool completely on a cooling rack.
- Make the frosting by creaming together softened butter, powdered sugar, vanilla, and just enough milk for thinning (add 1 Tbsp. at a time and mix in between) in the bowl of an electric mixer. Cream it for 2-5 minutes to make sure it's nice and creamy and fluffy!
- Frost the cooled cake, add extra jimmies on top for garnish, and enjoy!
