A donut lover’s cake: made with sour cream and freshly grated nutmeg for an old-fashioned donut taste, wrapped in a divine vanilla buttercream and piled high with mini deep fried donuts!
Donut Cake Inspiration
This may sound strange but sometimes I get baking inspo from from items that belong to my toddler. Maybe it’s because her stuff is so colorful and cute? She has this beautiful lamp in her room with a shade made of a purple and teal ombre colors which I once turned into a buttercream effect on a layered cake. Awhile back, her and I made my hidden rainbow cake using colors from her favorite rainbow pillow (check it out on my instagram highlights).
Recently, I was trying to get her to wear any of her pajamas except for her favorite donut pajamas which were dirty that day (I’m starting to think she might go to college in these pajamas!) and during our negotiation, I looked at the prized pjs in the pile of laundry, and a bizarre thought came into my head: that would make a really cute cake.
The cake of course was going to look like the pajamas had been designed after it (not the other way around… lol), it would be pink, piled high with vanilla glazed donuts, sprinkled with funfetti, just like the pajamas. For flavor, I always want to create some kind of connection to the interior of the cake’s flavor so rather than making another chocolate or yellow cake, I worked with KAF’s tender white cake recipe as a template and turned it into a sort of old fashioned donut flavor, made with sour cream and fresh nutmeg. It’s SO GOOD.
A donut lover’s donut cake
This is a great cake for donut lovers (and I should know, I have birthed the biggest donut lover ever!). Every slice will have not only that lovely taste of a yummy old fashioned donut, but on top, a piece of a fried donut. Also – yeah, you’re gonna make a lot of mini donuts and only use a handful for the cake. Trust me when I say that nobody in your family is going to complain about all those extra donuts!!
I can see this cake being the perfect centerpiece for donut-loving birthday peeps, with lots of yummy donuts for guests to snack on while they wait for the candles to be blown. Thank you toddler world for adorable pajamas that inspire baked goods and that are probably going to be worn until they literally start falling off her =)
sour cream donut cake
There’s a few steps to this cake, and here’s my advice on how to manage your time efficiently: first, make the buttercream a day ahead or more. If it’s only a day, leave it at room temperature in an air-tight container. If more, store it in the fridge and leave it out for a few hours to soften before you use it.
Second, make the cake. Store it, wrapped in plastic wrap and in an airtight container. If you aren’t using it the same day, store it in the freezer. The day before you want to serve the cake, make the donut dough as it needs to develop in the fridge overnight. The morning of, fry your donuts. Leave them to cool while you prep the cake with buttercream. Once the donuts are cool, make your glaze and decorate the donuts. Once the glaze is set, place them on the cake. Voila!

Tips on making Sarah’s mini donuts:
If you measure your flour and are very precise, the dough will be very soft (and wonderfully so!) but also very sticky. Flour your surface really well before you roll out the dough, and before you transfer the cut donut to the parchment paper, gently dust its bottom in flour to avoid it sticking to the parchment paper.
Flouring your donut cutter between each cut will help keep it from sticking.
I don’t have a deep fryer so I did the dutch oven and (in my case) a laser thermometer method. I love my laser thermometers because it doesn’t go into the oil and so, less mess! One thing to keep in mind is that the oil will take time to get to 365 and sometimes with a dutch oven you want to be careful about temperature so as not to damage it. I turn mine on medium-low for about 10 minutes and then up to medium-high to get it to where I want it. It can take a full 15-20 minutes to get to the right temperature; don’t put any donuts in until you get it to 365.
I found that as many as four donuts at a time was more than enough to keep track of when frying – these cook fast!
Sarah is right – the dough you have to re-roll to cut will not be as pretty. Make sure you save the first ones for the cake!
Vanilla donut glaze recipe
- 1 cup organic powdered sugar, sifted
- Pinch salt
- 1 tablespoon milk
- 1 teaspoon vanilla
Sift the powdered sugar into a bowl and add the salt, vanilla, and milk, whisk to combine.
The glaze might seem thick and you may need to add more milk but be very careful adding, you want it quite thick – think elmer’s glue.
Dipping the donuts in face down results in a better coverage rather than spooning it on. Once you’ve dipped, lift it up and move it from side to side for full coverage.
Add sprinkles as soon as you have glazed your donuts – it sets fast.
