How to Make Keto Boston Cream Donuts
Whisk the egg yolks in a small bowl and set aside. This forms the base for your rich pastry cream, ensuring it has a lovely, velvety texture.
Heat the heavy cream and butter on the stove, whisking often, until bubbles form around the edges. This step brings out the flavors and gets the mixture ready for the sweetener.
Combine the sweetener, salt, and xanthan gum with the hot mixture while whisking continuously. Afterward, remove the pot from the heat and add a bit of the hot mix to the egg yolks, whisking quickly to prevent scrambling.
Return everything to the pot and whisk constantly over medium heat for about 2-3 minutes, until thickened. You’ll know it’s ready when it coats the back of a spoon beautifully.
Chill the pastry cream by removing it from the heat and mixing in vanilla extract. Let it cool completely in the refrigerator until you’re ready to fill your donuts.
Preheat the oven to 350 °F, ensuring it reaches the perfect baking temperature for those delightful donuts.
Mix the almond flour, sweetener, baking powder, xanthan gum, and salt in a small bowl. This dry mix will create a solid base for the dough.
Melt the mozzarella in a bowl in the microwave, using 30-second increments until it’s stirrable about one minute total should do the trick!
Incorporate the whisked egg and dry ingredients into the melted mozzarella, mixing until a dough starts to form. This will be the foundation of your donuts!
Knead the dough by hand until well combined; if it’s too sticky, you can microwave it for an extra 10-15 seconds. Aim for a smooth and pliable consistency.
Roll out the dough between two sheets of greased parchment paper to about an inch thick. This ensures that your donuts will have the right shape and thickness for baking.
Cut out circular shapes using a glass, then re-roll the scraps to use up all the dough. You’ll want enough for everyone to enjoy!
Bake the dough cutouts on a cookie sheet for 25-30 minutes until they are golden brown. Keep an eye on them; the aroma will be irresistible!
Slice each cooled donut in half and fill it with the prepared pastry cream. Then, place the top half back on such a beautiful sight!
Prepare the chocolate glaze by heating up the heavy cream in the microwave for 1 minute, then pouring it over the chocolate chips and vanilla extract.
Stir until smooth, microwaving for an additional 10-15 seconds if necessary. You want that gorgeous glaze to be perfectly silky!
Spoon the warm glaze over the top of each donut, spreading it out evenly for a beautiful finish. Get ready for a tasty treat!

Keto Boston Cream Donuts Recipe FAQs
What type of mozzarella is best for the dough?
Absolutely! For the best results, use low-moisture mozzarella; it melts beautifully and creates that lovely chewy texture. Avoid fresh mozzarella, as it contains more moisture and can make the dough too sticky.
How should I store leftover donuts?
You can keep your Keto Boston Cream Donuts in an airtight container at room temperature for up to 2 days. For longer freshness, store them in the refrigerator, where they ll stay good for about 5 days. Just remember, the creamy filling is best enjoyed when fresh!
Can I freeze Keto Boston Cream Donuts?
Certainly! To freeze, wrap each donut tightly in plastic wrap and place them in a freezer-safe bag. They can be stored for up to 2 months. To enjoy, simply thaw overnight in the fridge, and if you like them warm, pop them in the microwave for 10-15 seconds before serving.
What should I do if my dough is too sticky?
If your dough is proving too sticky to handle, simply knead a little more almond flour into it, a tablespoon at a time, until it reaches the desired consistency. Additionally, microwaving the dough for 10-15 seconds can help make it more manageable for rolling and cutting.
Are these donuts suitable for people with nut allergies?
These Keto Boston Cream Donuts contain almond flour, so they’re not safe for individuals with nut allergies. You can try substituting it with a nut-free blend or coconut flour, but keep in mind that you may need to adjust the liquid ingredients for the best texture.
Can pets eat any part of these donuts?
It’s best to keep these donuts away from pets, as the sweetener used (monkfruit/erythritol) might be harmful to them if ingested in large amounts. Sugar-free chocolate can also be toxic to dogs, so it’s safest for our furry friends to stick to their own treats!
