Preheat the oven to 375°F (190°C) and line a baking sheet with parchment paper.
Mix dry ingredients: In a large bowl, whisk together almond flour, coconut flour, baking powder, xanthan gum, salt, and yeast (if using).
Prepare wet ingredients: In a separate bowl, mix the melted butter, apple cider vinegar, and eggs. Then stir in the almond milk.
Combine wet and dry ingredients: Slowly pour the wet ingredients into the dry ingredient mixture, mixing thoroughly until a dough forms. The dough will be slightly sticky but should hold its shape.
Shape the bolillos: Divide the dough into 6 equal portions. Roll each portion into a ball and then shape them into an oval, typical of bolillos. Use a knife to make a small slit on top of each roll.
Bake: Place the shaped rolls on the prepared baking sheet and bake for 20-25 minutes, or until the tops are golden brown and firm to the touch.
Cool and serve: Let the bolillos cool slightly on a wire rack before serving. You can enjoy them with butter, cheese, or your favorite keto-friendly fillings.
Tips:
For extra crispness, spray the rolls with a bit of water before baking.
Adding the yeast is optional since it won’t cause the dough to rise but will add a traditional bread flavor.
