Frosted Vanilla Custard Donuts (Low Carb, Gluten Free)

Vanilla custard is traditionally made with plenty of egg yolks, which are what make these donuts so rich and delicious. The batter rises up light and airy, so they have a tender crumb. If desired, this recipe would make wonderful cupcakes, but I like using my donut pan and filling each cavity high enough with batter that the hole of the donut disappears as it bakes, creating the perfect little platform for holding the dab of frosting. I just happen to have some decorating icing tips in my kitchen collection, so I had fun making them fancy and appropriate for Valentine’s Day, but that’s not necessary. Anyway you decorate them, these donuts will be both beautiful and delicious!

Frosted Vanilla Custard Donuts

Makes 8 donuts (more or less depending on your donut pan)

1 cup almond flour

1/4 cup erythritol sweetener, granulated

2 tablespoons unflavored whey protein powder

1 teaspoon baking powder

1/4 teaspoon vanilla powder (or seeds scraped from a vanilla bean)

1/8 teaspoon salt

1 large egg

2 egg yolks

1/4 cup heavy cream

1/4 cup almond or coconut milk

2 tablespoons butter, melted

1/2 teaspoon vanilla extract 

Frosting:

2 ounces cream cheese, room temperature

1 tablespoon butter, softened

4 ounces plain mascarpone cheese, room temperature

1/4 cup powdered erythritol (Confectioners), or to taste

1 teaspoon vanilla extract

2 tablespoons heavy cream

1. Preheat oven to 325 degrees F. Spray each cavity of your donut tin with non-stick cooking spray or grease with butter; set aside.

2. In a large bowl, whisk or sift together the almond flour, erythritol, whey protein powder, baking powder, vanilla powder and salt. Whisk to combine and until no lumps remain.

3. In a separate bowl, whisk together the egg, egg yolks, cream, almond milk, melted butter and vanilla extract. Add the wet ingredients to the dry ingredients and whisk well to combine. 

4. Fill each donut cavity to almost full. Be sure to fill each cavity until almost to the top because you want the donuts to puff up and fill in the hole as they bake, so there’s a place in the center of the donut to hold the frosting later. (see photo below) Bake for 14-16 minutes or until the edges are golden brown and the tops are just firm to the touch. Remove from the oven and let the donuts cool 10 minutes in the pan, then flip them onto a wire rack to cool completely.

5. To make the frosting: Whip together the room temperature cream cheese, butter and mascarpone cheese until fluffy using a handheld or standing electric mixer. Add the powdered erythritol and vanilla and beat until combined. Add the heavy cream 1 tablespoon at a time until the desired spreading consistency is reached. Taste and adjust sweetness to your taste. If desired, put the frosting into a piping bag with a decorator tip and pipe (or spoon) a tablespoon or so of the frosting into the center of each donut. (Note: This recipe for frosting will yield more than you need for eight donuts, which allows for dividing the frosting into batches and coloring each differently, if desired. Save any leftover frosting in an airtight container in the refrigerator to use for another recipe.)
