Heat a small pan on a burner on medium heat to melt the mozzarella together with cream cheese. You can also do this in a microwave. Make sure to occasionally stir the mixture.
To the pan, add white wine vinegar, egg, almond flour, salt, and garlic powder. Mix them well.
On a baking dish lined with parchment paper, take the dough and shape it into a round crust of 8 inches or 20 cm in diameter.
Prick the crust with a fork, place it in the oven to bake for about 12 minutes. Wait for the bread to turn golden brown. Once cooked, let the bread cool for a little while.
For the spread, take butter, garlic, salt, and rosemary in a bowl and mix them. Spread the garlic and rosemary butter on top of the bread and give it 10 minutes in the oven.
Cut the bread into smaller 8 to 10 pieces and serve when lukewarm.
