Preheat the oven to 300° and line two baking sheets with parchment paper. Set aside.
Separate the eggs. Add the cream of tartar to the whites and beat with a stand mixer or hand mixer until very stiff peaks form. Set aside.
Microwave the cream cheese for about 20-30 seconds, until it can be stirred smooth. Stir smooth and add one egg yolk at a time, stirring until completely smooth. Add the salt, garlic powder and onion powder.
Fold the egg yolk mixture into the egg whites until fully combined. Scoop 1/3 cup portions onto the parchment paper and spread into 4-5 inch circles, making sure to keep it quite tall, about ¾ inch. Leave 2 inches between the circles.
Bake for 20-22 minutes until firm and golden brown. Let cool on the baking sheet before transferring to a cooling rack or serving plate.
