Preheat your oven to 375°F (190°C) and line a muffin tin with paper liners.
In a large mixing bowl, combine the flour, sugar, and baking powder.
In a separate bowl, whisk together the eggs, milk, and melted butter until smooth.
Pour the wet ingredients into the dry ingredients and gently stir until just combined. Avoid overmixing.
Carefully fold in the raspberries, cream cheese chunks, and chocolate chips, being gentle to avoid breaking the raspberries.
Scoop the batter into the muffin tin, filling each cup about 3/4 full.
Bake for 20–25 minutes, or until the tops are golden and a toothpick inserted in the center comes out clean.
Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
