I absolutely love celebrating all those little holidays like sister day, pie day, etc. One of our favorites around this time is Doughnut Day. I often come up with my own donut recipe every year around this holiday just to mark the occasion. This time around, I whipped up these strawberry custard doughnuts and they were a hit. Of course, I just had to share them with you because I knew a good doughnut recipe couldn’t be kept a secret. By the way- do you say donut or doughnut?
Did you know that National Doughnut Day started in 1938 as a fundraiser for the Salvation Army? Many of us celebrate these holidays without even knowing the real meaning behind them. Of course, I’m all for celebrating a holiday around sweets, but I’m all for the fact that it also celebrates such a good cause. Especially because the Salvation Army still exists to this day and does so much for those in need. So, when you’re eating your custard-filled donut, think about “doughnating” as well (see what I did there?).
How to Make Strawberry Custard Filled Doughnuts
- Prepare the strawberries - In a bowl, mix together the diced strawberries and a tablespoon of sugar. Set them aside for later use.
- Get the custard simmering - In a small heavy-bottomed pot, combine the heavy cream, milk, and salt. Mix and bring to a simmer before removing from heat.
- Make the egg mixture - In a bowl, mix eggs and sugar until they’re pale yellow. Slowly add the milk mixture to the egg mixture, consistently stirring until it’s all incorporated, then add in the cornstarch mixture and mix well.
- Return to the heat - Place the egg and milk mixture back over the heat for about three minutes or until it’s thickened and glossy. Remove it from the heat and mix in the butter and vanilla.
- Add strawberries and chill - Add the strawberries to the custard, stir, then chill until it’s ready to be used.
- Prepare donuts - In a small bowl, combine yeast and warm milk and wait until it “blooms” or looks foamy. Stir in melted butter, sugar, and eggs. Then add the flour and salt. Knead dough until smooth.
- Let dough rise and cut - Place dough in a bowl, cover, and allow to rise. Once risen, roll out to about ½-inch thick and cut out doughnuts with a 3-inch biscuit cutter. Cover doughnuts and allow them to rise again until double their size.
- Fry donuts - Fill a fryer with about 2 inches of oil, heat to 375 degrees, then fry each doughnuts, about 1 minute on each side. Remove from the fryer, place on a paper towel to drain, then toss in cinnamon and sugar.
- Fill donuts - Place custard in a piping bag and fill each doughnut, serve, and enjoy!
Tips and Variations
- Make custard ahead - The strawberry custard can be made up to 2 days ahead of time, if desired. This will save some time in the process.
- Don’t rush the yeast - Make sure the yeast has time to do its thing. If not, your doughnuts won’t rise right, if at all, and you’ll have to start over and nobody wants that.
- Make it quicker - To make the process quicker, use a mixer fitted with the hook attachment to knead the dough quickly. I love using my KitchenAid for this as it cuts the kneading time in half! As mentioned, you can also make the custard ahead of time.
- Flour your surfaces - When you’re kneading or rolling out your dough on a counter, make sure whatever surface you’re using is floured so the dough doesn’t stick to everything, making a mess.
- Cut out the doughnut rounds- Use a simple round cookie cutter or a water glass. Then, let the rest and rise again.
- Fry them- You want your oil to be approximately 375 degrees. While a thermometer is your best bet to get the optimal temperature, you can also test a small amount of dough. You want it to be a nice golden brown after about 1 minute.
- Roll in sugar- Let the doughnuts cool on a paper towel for a few minutes, then roll them in sugar, and allow to cool completely.
- Fill with custard- fill the cooled doughnuts by making a hole down the center and inserting the pastry bag filled with the custard.
- Enjoy immediately- You'll want to eat these fresh and the same day for optimal flavor.
Common Questions About Strawberry Custard Filled Doughnuts
What Are Custard Filled Donuts Called?
Each type of custard-filled donut can have various names. However, custard-filled doughnuts are popularly referred to as Bavarian cream donuts or Boston cream doughnuts. This is because the custard in doughnuts is largely similar to a Boston cream pie. However, everyone has their own nickname for these types of donuts, especially since the flavors can largely vary between custards and styles.
What Can I make with Leftover Egg Whites?
Keep those egg whites to make a delicious Swiss Meringue Buttercream, Angel Food Cake, Pavlova, or just a simple egg white omelet. Egg whites can also easily be frozen for future use.
