Line the pan: Place paper or silicone liners in a 12-cup muffin tin.
This makes unmolding clean and easy.
Make the crust: In a bowl, mix 1 1/4 cups graham cracker crumbs, 3 tablespoons melted butter, 1 tablespoon brown sugar, a pinch of salt, and a small pinch of cinnamon. Stir until the crumbs feel like damp sand.
Press the base: Divide the mixture evenly among the 12 liners (about 1 to 1 1/2 tablespoons each). Press firmly with the back of a spoon or the bottom of a small glass to compact.
Set aside.
Soften the cream cheese: In a medium bowl, beat 8 ounces reduced-fat cream cheese until smooth and fluffy. This helps avoid lumps later.
Blend the filling: Add 1 cup plain Greek yogurt, 1/3 to 1/2 cup vanilla protein powder (start with 1/3 cup), 2 to 3 tablespoons honey, 1 teaspoon vanilla extract, 1 teaspoon lemon zest, and 1 tablespoon lemon juice. Beat or whisk until silky.
Taste and adjust sweetness or protein powder for thickness. The texture should be creamy but scoopable.
Make the blueberry compote: In a small saucepan, add 1 1/2 cups blueberries (fresh or frozen), 1 to 2 tablespoons honey, a squeeze of lemon juice, and a tiny pinch of salt. Cook over medium heat for 3 to 5 minutes, stirring, until the berries release their juices and soften.
Thicken the compote: Stir 1 teaspoon cornstarch with 1 tablespoon cold water to make a slurry.
Pour into the saucepan and cook 30 to 60 seconds more, until slightly thickened and glossy. Remove from heat and let cool to room temp.
Fill the cups: Spoon the cheesecake filling evenly over the crusts, smoothing the tops.
Swirl the blueberry: Add a spoonful of cooled blueberry compote on top of each cup. Swirl gently with a toothpick or the tip of a knife for a marbled look, or keep it as a neat layer.
Chill to set: Refrigerate for at least 2 hours, ideally 4.
The cups will firm up and the flavors will meld.
Garnish and serve: Top with extra blueberries, a sprinkle of graham crumbs, or a touch of lemon zest. Peel off the liners and enjoy cold.
Make-ahead tip: You can make the compote and crust a day ahead. Assemble the day you plan to serve for best texture.
