Ingredients

Cookies:

• 1½ cups blanched almond flour
  
  

• ¼ cup coconut flour
  
  

• ½ cup powdered sugar‑free sweetener (erythritol/monk fruit)
  
  

• ¾ tsp baking powder
  
  

• ¼ tsp salt
  
  

• 6 tbsp unsalted butter, softened
  
  

• 2 large eggs
  
  

• ½ tsp vanilla extract
  
  

• ¼ cup sour cream (helps keep them super soft)
  
  

Frosting:

• ¼ cup unsalted (or salted) butter, softened
  
  

• ½ cup powdered sugar‑free sweetener, sifted for smoothness
  
  

• 2 tbsp heavy cream (optional for texture)
  
  

• 1/4 tsp almond extract (or additional vanilla)
  
  

• Natural pink food coloring (optional)
  
  

• Dye‑free sprinkles (optional)
  
  

Directions

1. Preheat your oven to 350 °F (175 °C) and line a baking sheet with parchment.
   
   

2. In a bowl, whisk together almond flour, coconut flour, sweetener, baking powder, and salt.
   
   

3. In another bowl, cream softened butter and sweetener until light. Mix in eggs, vanilla, and sour cream until smooth.
   
   

4. Combine wet and dry ingredients until dough forms. Cover and chill for 1–2 hours to firm up.
   
   

5. Form dough into 12 equal balls, place on the baking sheet, and gently flatten each.
   
   

6. Bake 8–10 minutes, or until the edges just begin to set. Cookies will look pale—avoid overbaking. Let them cool completely.
   
   

7. To make the frosting, beat softened butter until smooth. Gradually add powdered sweetener, heavy cream, and extracts. Mix until creamy and fluffy; add food coloring if using.
   
   

8. Once cookies are fully cooled, spread frosting generously on each. Add sprinkles if desired.
