Ingredients Method

Ingredients
  

  • Blanched almond flour (fine grind)
  • Hazelnut flour or finely ground roasted hazelnuts
  • Unsweetened cocoa powder (Dutch-process or natural)
  • Erythritol, allulose, or a monk fruit blend (granulated)
  • Baking powder (aluminum-free)
  • Fine sea salt
  • Instant espresso powder (optional, enhances chocolate)
  • Eggs (room temperature)
  • Greek yogurt or full-fat sour cream
  • Unsalted butter (melted and cooled) or refined coconut oil
  • Vanilla extract
  • Hazelnut extract (optional but great for aroma)
  • Sugar-free dark chocolate chips or chopped sugar-free chocolate
  • Chopped roasted hazelnuts (optional, for topping)
  • Nonstick spray or silicone muffin liners

Method
 

  1. Preheat and prep: Heat the oven to 350°F (175°C). Line a 12-cup muffin tin with silicone liners or paper liners lightly sprayed with nonstick spray.
  2. Mix dry ingredients: In a large bowl, whisk together 1 1/2 cups almond flour, 1/2 cup hazelnut flour, 1/3 cup cocoa powder, 1/2 to 2/3 cup keto sweetener (to taste), 2 teaspoons baking powder, 1/4 teaspoon salt, and 1/2 teaspoon espresso powder.
  3. Whisk wet ingredients: In a separate bowl, whisk 3 large eggs, 1/2 cup Greek yogurt or sour cream, 1/3 cup melted butter (cooled) or coconut oil, 1 1/2 teaspoons vanilla, and 1/4 teaspoon hazelnut extract if using.
  4. Combine: Pour the wet ingredients into the dry. Stir with a spatula until just combined. The batter will be thick but scoopable. Fold in 1/2 cup sugar-free chocolate chips.
  5. Portion: Divide the batter evenly among the 12 cups. If you like, sprinkle a few chopped hazelnuts and extra chips on top for texture.
  6. Bake: Bake for 18–22 minutes, until the tops are set and a toothpick comes out with just a few moist crumbs. Do not overbake.
  7. Cool: Let muffins cool in the pan for 10 minutes, then transfer to a rack to finish cooling. Keto muffins firm up as they cool.
  8. Serve: Enjoy warm or at room temperature. A smear of butter or a dollop of whipped cream makes them feel extra special.
