Preheat and Prepare: Set your oven to 350°F (175°C). Line the baking sheet with parchment paper.
Combine Dry Ingredients: In a mixing bowl, whisk together almond flour, coconut flour, flaxseed, baking soda, and sea salt.
Blend Wet Ingredients: In a separate bowl, beat the eggs and add apple cider vinegar. Mix well.
Create Dough: Combine the wet and dry ingredients, forming a dough. If it's too sticky, add a bit more almond flour.
Shape the Bagels: Divide the dough into equal portions and shape them into rings, placing them on the prepared baking sheet.
Bake to Perfection: Bake for 25-30 minutes or until golden brown. Optional: Sprinkle sesame or poppy seeds on top before baking.
Serve and Enjoy: Allow the bagels to cool before slicing. Pair them with your favorite spreads or toppings.
