Set your oven to 375°F (190°C) and prepare a muffin tin with paper liners.
In a mixing bowl, combine the flour, baking powder, and salt by whisking them together.
In a separate bowl, beat the eggs with sugar until creamy, then add vanilla, heavy cream, and melted butter.
Combine the dry ingredients into the wet and stir until just mixed.
Fold in diced strawberries and optional cream cheese gently.
Divide batter evenly into the muffin cups, filling about ¾ of each.
Bake for 20 to 22 minutes, or until the tops are golden and a toothpick inserted in the center comes out clean.
Let cool on a rack and serve slightly warm or at room temperature.
