Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
In a large mixing bowl, combine almond flour, baking powder, garlic powder, onion powder, and salt. Mix well.
Add Greek yogurt and eggs to the dry ingredients, and mix until a dough forms. Knead the dough gently until smooth.
Divide the dough into 4 equal pieces and shape each piece into a bagel by forming a ring with a hole in the center.
Place the bagels on the prepared baking sheet, brush with a little olive oil, and sprinkle sesame seeds on top.
Bake in the preheated oven for 20-25 minutes or until golden brown.
Remove from the oven and let them cool slightly before serving.
