Ingredients

For the Keto Blueberry Donuts

1 ½ cups almond flour, finely blanched
¼ cup granulated keto-friendly sweetener, such as allulose or erythritol
2 tablespoons coconut flour
1 teaspoon baking powder
¼ teaspoon baking soda
¼ teaspoon salt
2 large eggs, room temperature
¼ cup unsalted butter, melted and slightly cooled
¼ cup unsweetened almond milk
1 teaspoon vanilla extract
½ cup blueberries, fresh or frozen
1 teaspoon lemon zest, optional but highly recommended

Optional Simple Glaze

½ cup powdered keto-friendly sweetener
1–2 tablespoons unsweetened almond milk
½ teaspoon vanilla extract
A tiny squeeze of fresh lemon juice, optional

Ingredient Notes

Almond Flour

Finely ground blanched almond flour gives these donuts their soft, tender texture. Avoid using coarse almond meal if possible because it can make the donuts heavier and grainier.

Coconut Flour

Coconut flour absorbs moisture extremely well, so you only need a small amount. It helps give the donuts structure without using traditional wheat flour.

Blueberries

Fresh blueberries work beautifully, but frozen blueberries are perfectly fine too. If using frozen berries, don’t thaw them first. Tossing them into the batter while frozen can help prevent excessive purple streaking.

Sweetener

Use a keto-friendly sweetener that works well for baking. Allulose tends to produce a softer texture, while erythritol can create a slightly firmer donut.

Lemon Zest

Lemon and blueberry are a classic combination. A little lemon zest brightens the berry flavor without making the donuts taste strongly lemony.

How to Make Keto Blueberry Donuts

Step 1: Prepare the Oven and Donut Pan

Preheat your oven to 350°F (175°C).

Lightly grease your donut pan with cooking spray or melted butter. Make sure you coat the corners and sides of each cavity so the baked donuts release easily.

Place the pan aside while you prepare the batter.

Step 2: Mix the Dry Ingredients

In a large bowl, whisk together the almond flour, coconut flour, keto sweetener, baking powder, baking soda, and salt.

Breaking up any lumps now will help create a smoother, more evenly textured batter.

Step 3: Combine the Wet Ingredients

In a separate bowl, whisk the eggs until smooth.

Add the melted butter, unsweetened almond milk, and vanilla extract. Whisk everything together until the mixture looks creamy and well combined.

If you’re using lemon zest, stir it into the wet ingredients now.

Step 4: Make the Donut Batter

Slowly pour the wet mixture into the bowl of dry ingredients.

Use a rubber spatula to gently fold everything together. Don’t overmix. The batter should be thick, smooth, and scoopable.

Finally, gently fold in the blueberries.

If you’re using frozen blueberries, fold them in carefully to avoid crushing the berries.

Step 5: Fill the Donut Pan

Spoon the batter evenly into the prepared donut cavities.

For the neatest results, transfer the batter to a piping bag or zip-top bag and pipe it into the pan.

Fill each cavity about ¾ full. Avoid filling them all the way to the top because the donuts will puff slightly while baking.

Step 6: Bake Until Golden

Place the pan in the preheated oven and bake for approximately 15–18 minutes.

The donuts should look lightly golden around the edges and feel firm but springy when gently touched.

A toothpick inserted into the thickest part should come out mostly clean.

Try not to overbake them. Because almond flour-based recipes can dry out when baked too long, removing the donuts when they’re just cooked through helps keep the centers soft and fluffy.

Step 7: Cool Completely

Let the donuts cool in the pan for about 5–10 minutes.

Then carefully turn them out onto a wire rack.

Allow them to cool completely before glazing. This is important because warm donuts can cause the glaze to melt and slide right off.

How to Make the Optional Sugar-Free Glaze

For a simple glaze, whisk together the powdered keto-friendly sweetener, almond milk, and vanilla extract.

Add the almond milk gradually until you reach a thick but pourable consistency.

Dip the cooled donuts into the glaze or drizzle it over the top.

For an extra pretty finish, add a few tiny blueberries or a little lemon zest before the glaze sets. 🫐

Serving Suggestions

These Keto Blueberry Donuts are delicious straight from the cooling rack, but there are plenty of ways to serve them.

For Breakfast

Pair one or two donuts with:

Scrambled eggs
Turkey or chicken sausage
Greek yogurt
Fresh coffee
Unsweetened tea

For Brunch

Arrange the donuts on a serving platter with berries, whipped cream, and coffee for an easy low-carb brunch spread.

For Dessert

Warm one donut slightly and serve it with a spoonful of sugar-free whipped cream.

For an extra special treat, drizzle a little melted sugar-free white chocolate over the top.

Pro Tips & Variations

For the fluffiest donuts, measure almond and coconut flour accurately rather than scooping directly from the bag. Too much flour can make the donuts dry.

For stronger blueberry flavor, gently mash a few blueberries before folding them into the batter. You can also add a teaspoon of lemon juice or extra zest for a bright berry-lemon combination.

Want chocolate? Add a small handful of sugar-free chocolate chips. For a cinnamon-blueberry version, add ½ teaspoon of cinnamon to the dry ingredients.

You can also skip the glaze and simply dust the cooled donuts with powdered keto sweetener for an easy everyday breakfast.

Storage Information

Refrigerator

Store cooled donuts in an airtight container in the refrigerator for up to 3–4 days.

Place parchment paper between layers if you’ve added glaze.

Freezer

For longer storage, freeze the unglazed donuts in a freezer-safe container or bag for up to 2–3 months.

For best results, wrap individual donuts before freezing to help prevent freezer burn.

Reheating

Let frozen donuts thaw in the refrigerator or at room temperature.

Warm them gently in the microwave for approximately 10–15 seconds if desired. Avoid overheating because it can make the donuts dry.

Frequently Asked Questions

Are Keto Blueberry Donuts low-carb?

Yes. These donuts use almond flour and coconut flour instead of traditional wheat flour and use a keto-friendly sweetener instead of regular sugar. However, exact carbohydrate counts depend on the ingredients and portion size.

Can I use frozen blueberries?

Absolutely! Frozen blueberries work well. Add them directly to the batter without thawing first.

Why are my keto donuts dry?

Overbaking is one of the most common reasons. Almond flour donuts can become dry if they stay in the oven too long. Remove them as soon as they’re cooked through.

Can I make these donuts without the glaze?

Yes! They’re delicious without the glaze. You can simply add a light dusting of powdered keto sweetener or enjoy them plain.

Can I use another low-carb flour?

Almond flour and coconut flour have different absorption properties, so substituting one directly for the other isn’t recommended. If changing the flour, use a recipe specifically developed for that flour.

Are these donuts good for meal prep?

Yes. Bake a batch ahead of time, cool them completely, and store them in the refrigerator for several days. They also freeze well without the glaze.
