Preheat and prep: Set your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or grease well.
Mix dry ingredients: In a large bowl, whisk 2 cups almond flour, 2 tablespoons coconut flour, 1/2 to 3/4 cup keto sweetener (adjust to taste), 2 teaspoons baking powder, 1/2 teaspoon salt, 2 teaspoons cinnamon, 1/2 teaspoon ground ginger, 1/4 teaspoon nutmeg, and a pinch of cloves.
Whisk wet ingredients: In a separate bowl, whisk 1 cup pumpkin purée, 3 large eggs, 1/3 cup melted coconut oil or butter, 1/4 cup unsweetened almond milk, and 1 teaspoon vanilla extract until smooth.
Combine: Pour the wet mixture into the dry ingredients. Stir gently until just combined.
If using add-ins, fold in 1/3 cup chopped nuts or sugar-free chocolate chips.
Portion: Divide the batter evenly among the muffin cups. The batter will be thick; that’s normal.
Bake: Bake for 18–22 minutes, or until the tops are set and a toothpick comes out mostly clean with a few moist crumbs.
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.
Optional finish: Dust lightly with a keto-friendly powdered sweetener mixed with cinnamon for a “bakery” look.
