Stir together the room temp cream cheese, sugar, cornstarch, and vanilla until everything's just blended.

Put flour, baking powder, and salt in a big bowl and set it aside. In another bowl, beat the egg and sugar together. Add in yogurt, oil, and vanilla and mix until it looks light yellow. Pour this wet mix into the dry stuff and stir until everything's mixed well. Carefully add half the blueberries and half the raspberries, making sure not to crush them and turn the batter pink. Save the rest of the berries for the top.

Drop about 1 1/2 tablespoons of batter into each paper cup. Press down a bit in the middle, then add a tablespoon of the cheese mix. Toss some berries on top and fill cups about 2/3 full. Pile on the crumble mix and press lightly so it sticks. Add a few more berries on top if you want.

Stick the muffins in the hot oven and turn the heat down to 350°F (175°C). Let them bake for 30-35 minutes until they're golden on top and firm in the middle.

Let the muffins sit in the pan for 5-10 minutes, then move them to a rack to cool completely. For the sweet drizzle, mix the powdered sugar with a bit of milk or cream. Start with just a teaspoon of liquid and add more until it's runny enough. Drizzle this over the cooled muffins before you eat them.
