Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners.
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
In a large bowl, cream the softened butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.
Mix in the sour cream until fully combined.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Gently fold in the diced peaches.
In a separate bowl, beat the cream cheese until smooth.
Add the honey, lemon juice, and cinnamon, mixing until well combined.
Fill each cupcake liner about halfway with the batter, then add a spoonful of the cream cheese mixture on top, followed by more batter to fill the liners about ¾ full.
Bake for 18-20 minutes or until a toothpick inserted into the center comes out clean.
Allow to cool in the pan for 5 minutes before transferring to a wire rack to cool completely.
