🕒 Time & Servings

• Prep Time: 15 minutes

• Cook Time: 20 minutes

• Total Time: 35 minutes

• Servings: 4 buns

• Best For: Breakfast, Brunch, Dessert

• Season: Great year-round

🧺 Ingredients

Dough:

• 1 ½ cups shredded mozzarella cheese

• 2 tablespoons cream cheese

• 1 cup almond flour

• 1 tablespoon coconut flour (optional)

• 1 large egg

• ½ teaspoon baking powder

• Pinch of salt

Filling:

• 2 tablespoons unsalted butter, softened

• 2 tablespoons brown sugar substitute (Swerve or Lakanto Golden)

• 1 tablespoon ground cinnamon

• ½ teaspoon vanilla extract

Frosting:

• 2 oz cream cheese, softened

• 1 tablespoon unsalted butter, softened

• 1 tablespoon powdered erythritol

• ¼ teaspoon vanilla extract

• 1–2 teaspoons heavy cream (adjust for texture)

🥣 Step-by-Step Instructions

1. Preheat and Prepare

Begin by preheating your oven to 375°F (190°C). Line a baking dish with parchment paper or lightly grease it with butter or coconut oil.

2. Melt the Cheese

In a microwave-safe bowl, combine the shredded mozzarella and cream cheese. Heat for 60 seconds, stir, then microwave for another 20–30 seconds until the mixture is fully melted and smooth.

3. Combine and Knead

Separately, whisk together the almond flour, coconut flour, baking powder, and salt. Pour the dry ingredients into the cheese mixture along with the egg. Stir well, then knead the dough with clean hands until fully combined. If the dough is sticky, refrigerate it for 5–10 minutes to firm it up.

4. Roll the Dough

Place the dough between two sheets of parchment paper. Roll it out into a rectangle approximately ¼ inch thick.

5. Make the Filling

In a small bowl, stir together the softened butter, brown sugar substitute, cinnamon, and vanilla. Spread this mixture evenly over the rolled dough.

6. Roll and Slice

Carefully roll the dough into a log shape, starting from the short edge. Once rolled, use a sharp knife or unflavored dental floss to cut the log into four equal buns.

7. Bake the Buns

Arrange the buns in the prepared baking dish. Bake for 18–20 minutes, or until the tops are golden and the edges firm up slightly.

8. Frost While Warm

As the buns bake, prepare the frosting by mixing all ingredients in a bowl until smooth and fluffy. Adjust consistency with a touch of cream, if needed. Let the buns cool slightly before spreading the frosting on top.

💡 Tips for Better Buns

• Sticky dough? Pop it in the fridge for a few minutes.

• Extra gooey rolls? Increase the butter in the filling slightly.

• Nut allergy? Swap almond flour with sunflower seed flour.

• Make-ahead option: These store well and reheat beautifully.

📦 Storage & Reheating

Store leftovers in an airtight container in the fridge for up to 4 days. For the best results, reheat them gently in the microwave (15–20 seconds) or a warm oven.

You can also freeze the buns before frosting. Thaw in the refrigerator overnight and frost before serving.
