Ingredients
- 6 tbsp coconut flour
- 1/3 cup brown sugar substitute
- 3 tbsp unflavored whey protein powder
- 1 1/2 tsp baking powder
- 3/4 tsp ground cinnamon
- 1/2 tsp ground ginger
- 1/2 tsp ground nutmeg
- 1/4 tsp salt
- 1/8 tsp ground cloves
- 3 large eggs (room temperature)
- 1/4 cup butter (melted)
- 1/4 cup water (room temperature)
- 1/2 tsp vanilla extract
- 4 ounces cream cheese (softened)
- 1/4 cup butter (softened)
- 1/3 cup powdered allulose, sifted
- 1 teaspoon ground cinnamon (more if you like)
- 1/2 tsp vanilla extract
- 2 tbsp heavy whipping cream (room temperature)
Instructions
- Step 1: Preheat the oven to 350ºF and line a standard muffin tin with 6 parchment or silicone liners.
- Step 2: In a large bowl, whisk together coconut flour, brown sugar substitute, whey protein powder, baking powder, cinnamon, ginger, nutmeg, salt, and cloves.
- Step 3: Stir in the eggs, melted butter, water, and vanilla extract until the batter is well combined and smooth. If the batter is too thick, add water 1 tablespoon at a time until easy to scoop.
- Step 4: Divide the batter evenly among the muffin cups and smooth the tops. Bake for 20 to 25 minutes until golden brown and the tops feel firm to the touch.
- Step 5: Remove from the oven and let the cupcakes cool in the pan for 15 minutes, then transfer them to a wire rack to cool completely.
- Step 6: For the frosting, beat the cream cheese and softened butter together on medium speed until very smooth, about 90 seconds.
- Step 7: Gradually add the sifted powdered allulose and beat until combined. If needed, sift the sweetener to remove clumps.
- Step 8: Add ground cinnamon, vanilla extract, and heavy whipping cream. Beat until smooth, scraping down the sides of the bowl as needed.
- Step 9: Taste the frosting and add more cinnamon or sweetener if desired. Then pipe or spread the frosting onto the cooled cupcakes.
Tips & Variations
- For a stronger spice flavor, increase the ground cinnamon in both the batter and frosting.
- If you prefer a dairy-free version, substitute coconut oil for butter and use a dairy-free cream cheese alternative.
- Make sure your eggs and water are at room temperature to help the batter mix evenly.
- Use silicone liners for easier cupcake removal and less mess during baking.
Storage
Store the cupcakes in an airtight container in the refrigerator for up to 5 days. Allow them to come to room temperature before serving for the best texture. You can also freeze the cupcakes without frosting for up to 3 months; thaw in the refrigerator overnight before frosting and serving.

FAQs
Can I use another flour instead of coconut flour?
Coconut flour behaves differently from other flours because it absorbs more liquid. Substituting with almond flour or regular flour will change the texture and may require different liquid amounts. For best results, follow the recipe as written.
What can I use if I don’t have a brown sugar substitute?
You can use another low-carb sweetener like erythritol or a blend of stevia and erythritol. Just be sure to use a quantity that equals 1/3 cup sweetness and adjust to taste.
