Preheat oven to 425°. Line a rimmed baking sheet with parchment paper or a Silpat.
In a medium mixing bowl, combine the almond flour, baking powder, garlic powder, and onion powder. Mix until well combined. I like to put the mixture through a flour sifter to ensure that all the baking powder gets mixed in with the rest of the ingredients.
Crack one of the eggs into a small bowl and fork whisk. This will be the egg wash for the top of the pretzels. The other two eggs will go in the dough.
In a large microwave safe mixing bowl, combine the mozzarella cheese and cream cheese. Microwave for 1 minute and 30 seconds. Remove from microwave and stir to combine. Return to microwave for 1 additional minute. Mix until well combined.
To the mixing bowl, add the remaining 2 eggs and the almond flour mixture. Mix until all ingredients are well incorporated. If the dough gets too stringy and unworkable, simply put it back in the microwave for 30 seconds to soften and continue mixing.
Divide the dough into 6 equal portions. Roll each portion into a long, thin piece, resembling a breadstick. Fold each one into the shape of a pretzel.
Brush the top of each pretzel with the egg wash.
Sprinkle coarse sea salt over top.
Bake on the middle rack for 12-14 minutes or until golden brown.
