Set up your base: In a medium bowl, whisk 1 cup plain Greek yogurt with 1 scoop (about 25–30 g) protein powder. Mix until smooth and no dry patches remain. If it looks thick, that’s fine.
Warm the liquid: In a small saucepan, add 1 cup milk and 2–3 tablespoons salted caramel sauce.
Warm over medium-low heat, stirring until fully combined. Do not boil.
Thicken it (choose your method): Cornstarch: Stir 1 tablespoon cornstarch with 2 tablespoons cold milk to make a slurry. Whisk into the warm caramel milk.
Cook 2–3 minutes, stirring, until slightly thickened.
Gelatin: Sprinkle 1 teaspoon unflavored gelatin over 2 tablespoons cold milk. Let bloom 5 minutes. Stir into the warm caramel milk until dissolved.
Add vanilla and salt: Remove from heat.
Stir in 1/2 teaspoon vanilla extract and a pinch (about 1/8 teaspoon) fine sea salt. Taste and adjust sweetness with a little maple syrup or sweetener if needed.
Combine and smooth: Slowly whisk the warm caramel mixture into the yogurt-protein bowl. Add it gradually to prevent lumps.
Whisk until glossy and uniform.
Chill to set: Pour into 4 small jars or bowls. Cover and refrigerate at least 2 hours (cornstarch) or 3–4 hours (gelatin), until set and creamy.
Finish and serve: Stir briefly before serving. Top with a drizzle of caramel, a sprinkle of flaky salt, and any extras like nuts or dark chocolate shavings.
