Ingredients Method

Ingredients
  

  • 1 3/4 cups almond flour (finely ground; not almond meal)
  • 1/3 cup unsweetened cocoa powder
  • 2/3 cup granulated erythritol or allulose (or your preferred keto sweetener)
  • 1 1/2 teaspoons baking powder
  • 1/4 teaspoon baking soda (helps lift and balance acidity)
  • 1/4 teaspoon fine sea salt
  • 3 large eggs, room temperature
  • 1/2 cup natural peanut butter (no added sugar; creamy)
  • 1/2 cup unsweetened almond milk (or other low-carb milk)
  • 1/4 cup melted coconut oil or unsalted butter
  • 1 teaspoon vanilla extract
  • 1/3 cup sugar-free chocolate chips (optional but recommended)
  • 1–2 tablespoons extra peanut butter for swirling on top (optional)

Method
 

  1. Prep the pan: Preheat the oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or lightly grease with coconut oil.
  2. Mix dry ingredients: In a large bowl, whisk together almond flour, cocoa powder, sweetener, baking powder, baking soda, and salt until no clumps remain.
  3. Combine wet ingredients: In a separate bowl or large measuring cup, whisk the eggs, peanut butter, almond milk, melted coconut oil (or butter), and vanilla until smooth.
  4. Make the batter: Pour the wet mixture into the dry ingredients. Stir with a spatula until just combined. Fold in the sugar-free chocolate chips if using. The batter will be thick.
  5. Fill the cups: Divide the batter evenly among the 12 muffin cups. If you want a peanut butter swirl, dot a small amount of peanut butter on top of each muffin and swirl with a toothpick.
  6. Bake: Bake for 18–22 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Do not overbake.
  7. Cool: Let muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. They firm up as they cool.
  8. Serve: Enjoy warm or at room temperature. For extra decadence, add a light dusting of powdered keto sweetener or a drizzle of melted sugar-free chocolate.
