Bake Strawberry Cream Cheese Muffins Recipe: tender muffins with cream cheese centers and fresh strawberries.
Preheat the oven to 425°F and line a 9-10 cup muffin tin with white paper liners, setting the prepared tin aside on the painted pine surface. This first action establishes oven temperature and the vessel that will receive the batter; keep the lined tin visible and ready, no baking yet.
Stir together the streusel flour, light brown sugar, and salt in a small bowl until evenly distributed. Pour in the melted unsalted butter and whisk with a fork until coarse, sandy crumbs form and clump slightly when pinched. Transfer the streusel to a shallow dish and set aside to cool and hold its crumbly texture.
In a large bowl whisk together the all-purpose flour, baking powder, and salt until homogenous and aerated. Keep the bowl on the surface and have measuring spoons and a small jar of granulated sugar nearby — everything ready for the wet ingredients to meet the dry.
In a medium bowl whisk the large egg with the granulated sugar until just combined and slightly pale, then whisk in the Greek yogurt, vegetable oil, and vanilla until the mixture is glossy and pale yellow. The texture should be smooth and slightly thick, with the oil fully emulsified into the yogurt-egg base.
Pour the wet mixture into the large bowl of dry ingredients and gently fold everything together by hand with a rubber spatula until there are no long streaks of flour. The batter should be thick, slightly coarse, and elastic — not over-mixed — with a pale yellow base that will become studded with fruit.
Using a rubber spatula, fold in the diced fresh strawberries until evenly distributed, leaving bright red flecks throughout the batter; reserve 2–3 tablespoons of diced strawberries to press on top of the muffins before baking. The batter is now the central in-progress result: glossy, speckled with fruit, and ready to be portioned into the lined cups.

Beat the room-temperature cream cheese with granulated sugar, cornstarch, and vanilla just until smooth and combined — a silky, slightly tangy filling that holds its shape but will soften when baked. Transfer to a small bowl or ramekin for easy scooping.
Spoon approximately 1 tablespoon of the strawberry batter into each paper-lined cup, creating a shallow base. Drop a not-quite-full tablespoon of the cream cheese mixture into the center of each cup so it sits above the batter base.
Cover each cream cheese dollop with more batter so each cup is about two-thirds to three-quarters full. Generously sprinkle the prepared streusel crumbs over each muffin, pressing a few reserved diced strawberry pieces gently into the crumbs so they cling and peek through the topping.
Place the filled muffin tin into the preheated oven (reduce the oven to 350°F as you slide it in) and bake 22–25 minutes, or until the tops are golden brown and the centers are set. Look for a firm, domed top with toasted streusel and strawberry accents.
Allow the muffins to rest in the pan for 5–10 minutes so the cream cheese centers settle, then transfer the muffins to a cooling rack to cool completely. The muffins should retain a moist interior, a crackled streusel crown, and visible pockets of softened strawberry.
Whisk the powdered sugar with 1 to 2 teaspoons of milk or cream, adding more liquid a drop at a time until a pourable, glossy glaze is achieved. Drizzle thin zigzag lines of glaze over the cooled muffins just before serving to add a bright white contrast and delicate sheen.
