DIY Donut Cake

We’ve got a serious donut and “sprinkler” obsession going on in our house right now.  Which, luckily, made it fairly easy when it came to picking a theme for Gracie’s 3rd birthday.  After scouring Pinterest, I decided that I had to at least try to make her a donut shaped cake for the night of her actual birthday.

She had requested strawberry cake, which was easy enough, but the rest made me a little nervous.   I’m not a baker — I tend to leave that to Gracie and Mom Mom.  I can bake just fine, but it’s not my passion.  So when words like fondant are being tossed around, it made hesitate oh so slightly.

In the end, I jumped in, decided to film this adventure, and I’m SO glad I did.  It came out incredibly well and I had a BLAST making it.  Maybe this will be my new thing…once a year, I’ll put on my chef’s hat and make some really cool cake for Gracie’s birthday.

The cake was enjoyed by our family after her birthday dinner and her reaction to the first cake sighting was priceless.  Don’t worry y’all, I caught it on film so go watch our very first day of Vlogmas ever. That’s another story for another day though.

The great thing about this cake was that it’s supposed to just be a donut.  Those aren’t perfect even if they may taste like it, so I wasn’t worried about smoothing out every bump or making the fondant just exactly right.  I felt free to take some artistic license in the creation of this masterpiece.  That’s right, I said it.  It’s a freaking masterpiece.

DIY Donut Cake


  • Donut cake mold
  • 1 box strawberry cake mix
  • 3/4 C milk
  • 3/4 oil
  • 1 cup finely chopped fresh strawberries
  • 4 large eggs
    For the decorations
  • 2 cans fluffy white frosting
  • 1 1/2 teaspoons strawberry extract
  • Wilton Copper & Brown food coloring
  • Powder sugar or corn starch, for dusting your work surface
  • Pink fondant
  • Sprinkles


  1. Preheat your oven to 350 degrees F. Grease and flour your cake mold well.
  2. Add your cake mix, milk, oil, eggs, and strawberries into a large bowl. Beat with an electric mixer on low for about 30 seconds. Stop to scape down the sides of the bowl, and then continue to beat on medium until well combined.
  3. Pour half of your batter into each half of the donut cake mold.
  4. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. *Adjust baking time as needed for your particular mold.
  5. While the cake is cooling, add both cans of frosting to another large bowl. Add in the strawberry extract and stir to combine.
  6. Add in one swirl of Copper food coloring, and then slowly begin adding in the Brown until your desired donut color is achieved. Transfer to a piping bag or large zip lock bag.
  7. Once the cake is completely cool, use a serrated knife to level your cake halves. Pipe a generous amount of frosting onto your bottom cake half and spread it out using an off set spatula until you have an even layer. Carefully place the top half on top.
  8. Frost the entire outside of the cake, using your off set spatula to smooth out the frosting and create a mostly even surface.
  9. Place your frosted cake in the fridge for 30 minutes to allow your frosting to set.
  10. To make your fondant workable, remove from the packaging and pop it into the microwave for about 20 seconds. *Start with 10 and work your way up since microwaves and fondant amounts may vary.
  11. On a piece of wax paper that has been lightly dusted with powder sugar, roll out your fondant until it's approximately 1/8" thick.
  12. Using a sharp knife, cut the edges of the fondant into waves that will resemble the drips of donut glaze. Cut a hole in the center of the fondant that is about the size of the center of your donut cake, and repeat the process of creating drip-like edges.
  13. Gently place your fondant on top of your cake and press down lightly so that it sticks.
  14. Paint the fondant with a little bit of water and add your sprinkles. Work in small sections so that your sprinkles will be evenly distributed.
  15. Enjoy!
