To prepare a yogurt bark recipe, first you need to gather your ingredients. First, you'll need: 1 cup (240 ml) plain yogurt, 1 tbsp. vanilla extract, and 1 tablespoon (2.5 g) honey. You can use any flavor of yogurt you like, as long as it's not too sweet. If you don't want to use vanilla, then you can skip this step and just use regular yogurt. Mix the ingredients together until they're well combined. Pour the mixture into an oiled parchment paper-lined baking sheet and bake for 20 to 25 minutes, or until the top is golden brown. Allow the bark to cool completely before cutting it into squares.
