Ingredients for Keto Blueberry Donuts

These simple ingredients combine to create a delicious low-carb donut.

For the Donuts

• 2 cups almond flour

• ¼ cup coconut flour

• ½ cup keto sweetener (erythritol or monk fruit)

• 1 teaspoon baking powder

• ¼ teaspoon salt

• 3 large eggs

• ¼ cup melted butter or coconut oil

• ½ cup unsweetened almond milk

• 1 teaspoon vanilla extract

• ½ cup fresh or frozen blueberries

Optional Keto Glaze

• ¾ cup powdered keto sweetener

• 2–3 tablespoons almond milk

• ½ teaspoon vanilla extract

Equipment Needed

To prepare this recipe successfully, you’ll need:

• Mixing bowls

• Whisk or electric mixer

• Donut pan

• Spatula

• Cooling rack

A donut pan helps create the classic donut shape, but you can also use a muffin tin if you don’t have one.

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Grease your donut pan lightly with butter, coconut oil, or cooking spray to prevent sticking.

Step 2: Combine the Dry Ingredients

In a large mixing bowl, whisk together:

• Almond flour

• Coconut flour

• Keto sweetener

• Baking powder

• Salt

Mix well so that the ingredients are evenly distributed.

Step 3: Prepare the Wet Ingredients

In a separate bowl, whisk together:

• Eggs

• Melted butter or coconut oil

• Almond milk

• Vanilla extract

Mix until the ingredients are smooth and fully combined.

Step 4: Mix the Batter

Slowly pour the wet ingredients into the dry ingredients while stirring gently. Continue mixing until a smooth batter forms.

Once the batter is ready, gently fold in the blueberries. Be careful not to overmix, as this can break the berries and discolor the batter.

Step 5: Fill the Donut Pan

Spoon or pipe the batter into the donut pan, filling each cavity about three-quarters full. Smooth the tops slightly with a spoon.

Step 6: Bake the Donuts

Place the donut pan in the oven and bake for 15–18 minutes, or until the donuts are lightly golden and a toothpick inserted into the center comes out clean.

Allow the donuts to cool in the pan for about 5 minutes, then transfer them to a cooling rack.

Making the Keto Glaze

For a sweet finishing touch, prepare a simple keto glaze.

In a small bowl, combine:

• Powdered keto sweetener

• Almond milk

• Vanilla extract

Whisk until smooth. If the glaze is too thick, add a small amount of almond milk until the desired consistency is reached.

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

Tips for Perfect Keto Donuts

Use Fine Almond Flour

Finely ground almond flour produces the best texture for baked keto goods.

Avoid Overbaking

Overbaking can cause keto baked goods to become dry, so keep an eye on the donuts during the final minutes.

Fold the Blueberries Gently

Mixing too vigorously can crush the blueberries and turn the batter purple.

Let the Donuts Cool Before Glazing

If the donuts are too warm, the glaze may melt and slide off.

Flavor Variations

These keto blueberry donuts are delicious on their own, but you can easily customize the recipe.

Lemon Blueberry Donuts

Add 1 teaspoon lemon zest to the batter and a little lemon juice to the glaze for a refreshing citrus flavor.

Cream Cheese Blueberry Donuts

Mix 2 tablespoons softened cream cheese into the batter for a richer texture.

Cinnamon Keto Donuts

Add ½ teaspoon cinnamon to the batter for a warm spice flavor.

Chocolate Blueberry Donuts

Add a handful of sugar-free chocolate chips to the batter for a decadent twist.

Storage Instructions

Proper storage helps keep the donuts fresh and delicious.

Room Temperature

Store the donuts in an airtight container for up to 2 days.

Refrigerator

Refrigerate the donuts for up to 5 days.

Freezer

You can freeze the donuts for up to 2 months. Thaw them overnight in the refrigerator and warm slightly before serving.
