Preheat the oven to 350°F and line a baking sheet with parchment. Sticky caramel disasters are not welcome.
Whisk together flour, cocoa powder, espresso powder, baking soda, and salt. No lumps allowed.
Beat melted butter, brown sugar, and granulated sugar until smooth. No shortcuts.
Mix in the egg and vanilla extract until fully incorporated. The dough should look dangerously good.
Slowly add dry ingredients to the wet mixture, stirring until just combined. Overmixing ruins everything.
Fold in chocolate chips and caramel pieces. Try not to eat them all.
Scoop tablespoon-sized portions onto the baking sheet, spacing them 2 inches apart. No overcrowding.
Bake for 12 minutes, or until the edges are set but the centers remain slightly soft. Trust the gooey process.
Cool on the baking sheet for 5 minutes, then transfer to a rack. Or just eat them now.
Pair with coffee, milk, or pure happiness. No regrets.
