Ingredients
  

  • 2 cups (200 g) fine almond flour
  • 2 tablespoons coconut flour
  • 1 tablespoon baking powder (aluminum-free)
  • 1/2 teaspoon fine sea salt
  • 2/3 cup granulated or powdered erythritol/monk fruit blend (adjust to taste)
  • 3 large eggs, room temperature
  • 1/3 cup melted butter (or coconut oil), slightly cooled
  • 1/3 cup sour cream (or full-fat Greek yogurt)
  • 1 teaspoon vanilla extract
  • 1–2 teaspoons orange zest (optional but recommended)
  • 1–2 tablespoons unsweetened almond milk (as needed for batter consistency)
  • 1 cup fresh or frozen cranberries, halved if large
  • Optional: 1–2 tablespoons sugar-free orange marmalade or a few drops orange extract

Method
 

  1. Preheat and prep: Heat the oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or grease well. This helps prevent sticking and keeps edges tender.
  2. Mix dry ingredients: In a large bowl, whisk almond flour, coconut flour, baking powder, salt, and sweetener until no lumps remain. Breaking up clumps helps the muffins rise evenly.
  3. Whisk wet ingredients: In a separate bowl, whisk eggs, melted butter, sour cream, vanilla, and orange zest. Make sure the butter isn’t hot, or it can scramble the eggs.
  4. Combine: Pour wet ingredients into the dry. Stir with a spatula until just combined. If the batter looks too thick (it should be scoopable, not dry), stir in 1–2 tablespoons almond milk.
  5. Fold in cranberries: Gently fold in the cranberries so they’re evenly distributed. If using frozen, do not thaw; add straight from the freezer to avoid bleeding color.
  6. Portion: Divide batter among the muffin cups, filling about 3/4 full. For taller domes, you can slightly mound the batter.
  7. Bake: Bake for 18–22 minutes, or until the tops are lightly golden and a toothpick comes out clean or with a few moist crumbs. Almond flour browns quickly, so keep an eye on them.
  8. Cool: Let muffins cool in the pan for 10 minutes, then transfer to a wire rack. This helps set the crumb and prevents them from breaking apart.
  9. Optional glaze: For a bakery-style finish, whisk 1/3 cup powdered keto sweetener with 1–2 teaspoons almond milk and a few drops orange extract. Drizzle over cooled muffins.
