Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
Baked Donuts
1 1/2 cups almond flour
1/4 cup coconut flour
1/3 cup granulated sugar-free sweetener (erythritol or monk fruit blend)
1 1/2 teaspoons baking powder
1/4 teaspoon salt
3 large eggs
1/3 cup unsweetened almond milk
1/4 cup unsalted butter, melted
1 teaspoon vanilla extract
1/2 cup sugar-free chocolate chips
1/4 cup heavy cream
1 tablespoon unsalted butter
Directions
Preheat your oven to 350°F (175°C). Lightly grease a donut pan or use a silicone donut mold.
In a large bowl, whisk together almond flour, coconut flour, sugar-free sweetener, baking powder, and salt.
In a separate bowl, beat the eggs. Add almond milk, melted butter, and vanilla extract. Mix until smooth.
Combine the wet ingredients with the dry ingredients and stir until fully incorporated. The batter should be thick but pipeable.
Spoon or pipe the batter evenly into the donut molds, filling each cavity about 3/4 full.
Bake for 15–18 minutes or until the donuts are lightly golden and a toothpick inserted comes out clean. Allow them to cool completely before filling.
To make the pastry cream, heat the almond milk in a saucepan over medium heat until it begins to steam, but do not boil.
In a separate bowl, whisk egg yolks, powdered sweetener, and cornstarch until smooth.
Slowly pour the warm milk into the egg mixture while whisking constantly to prevent scrambling.
Return the mixture to the saucepan and cook over medium-low heat, stirring continuously, until thickened (about 3–5 minutes).
Remove from heat and stir in butter and vanilla extract. Let the cream cool completely, then refrigerate for at least 1 hour to thicken further.
Transfer the pastry cream to a piping bag fitted with a small round tip. Insert the tip into the side or bottom of each donut and fill generously.
For the chocolate glaze, heat heavy cream in a small saucepan until warm. Remove from heat and add sugar-free chocolate chips and butter. Let sit for 2 minutes, then stir until smooth.
Dip the top of each filled donut into the chocolate glaze and place on a rack to set.
Allow the glaze to firm up before serving.
Servings and timing
Servings: 8 donuts
Preparation time: 20 minutes
Cooking time: 18 minutes
Cooling and filling time: 1 hour 15 minutes
Total time: Approximately 1 hour 50 minutes
Variations
For a dairy-free version, replace butter with coconut oil and use full-fat coconut milk instead of heavy cream.
To make them extra rich, add 1/2 teaspoon vanilla bean paste to the pastry cream.
For a mocha twist, mix 1 teaspoon instant espresso powder into the chocolate glaze.
You can also make mini donuts using a mini donut pan and reduce the baking time to 10–12 minutes.
Storage/Reheating
Store the filled donuts in an airtight container in the refrigerator for up to 4 days. Because of the pastry cream filling, refrigeration is necessary.
Before serving, let them sit at room temperature for 10–15 minutes for the best texture and flavor.
These donuts are not ideal for microwave reheating once filled, as the cream may separate. If you want to warm them slightly, heat the unfilled donuts briefly and fill afterward.
You can freeze the unfilled baked donuts for up to 2 months. Thaw completely before filling and glazing.
FAQs
Can I fry these donuts instead of baking them?
