Make the blueberry swirl: In a small pan over medium heat, warm 1 cup blueberries with 1–2 teaspoons sweetener and a squeeze of lemon. Cook 3–4 minutes until juicy and slightly thick.
Set aside to cool.
Cook the oats: In a saucepan, combine 1 cup rolled oats, 1 1/2 cups milk, a pinch of salt, and 1/2 teaspoon vanilla. Simmer 5–7 minutes, stirring, until creamy and most liquid is absorbed. Remove from heat.
Whisk the cheesecake base: In a bowl, mix 1/2 cup Greek yogurt, 2 tablespoons light cream cheese (softened), 1 scoop protein powder, 1/2 teaspoon vanilla, 1–2 teaspoons sweetener, and 1/2 teaspoon lemon zest.
Stir until smooth. If it’s too thick, add 1–2 tablespoons milk.
Combine: Stir the cheesecake base into the warm oats until fully blended. If you like it thicker, add 1 teaspoon chia seeds and let it sit 5 minutes to gel.
Swirl and serve: Spoon the blueberry mixture over the oats and swirl gently.
Top with extra fresh berries. For the full “cheesecake” touch, sprinkle a little crushed graham cracker or chopped nuts on top.
Overnight option: Skip cooking. In a jar, mix 1 cup oats, 1 cup milk, 1/2 cup Greek yogurt, 2 tablespoons light cream cheese, 1 scoop protein powder, 1 teaspoon vanilla, 1–2 teaspoons sweetener, 1 teaspoon chia seeds, and lemon zest.
Stir well, top with blueberries, and chill 4 hours or overnight. Stir before eating.
