Preheat your oven to 350°F (175°C). This step is crucial to ensure your rolls bake evenly and rise beautifully while infusing your kitchen with delightful aromas.

Mix together flour, cocoa powder, sugar, baking powder, baking soda, and salt in a large bowl. Stir these dry ingredients until well combined, creating the perfect foundation for your dough.

Combine the wet ingredients by whisking milk, melted butter, egg, and vanilla extract in another bowl. Ensure everything is well blended for a rich and moist roll texture.

Blend the wet ingredients into the dry ingredients, stirring gently until just combined. You want a soft, cohesive dough that isn’t overly worked—this will keep your rolls tender.

Roll out the dough into a rectangle about ½ inch thick on a lightly floured surface. Aim for even edges to help with rolling and cooking evenly.

Spread the brown sugar and cinnamon mixture over the dough, ensuring an even layer. This creates that irresistible sweet cinnamon flavor in every bite of your rolls.

Sprinkle chocolate chips on top of the sugar and cinnamon layer. Feel free to add more for an extra chocolatey experience—after all, who can resist?

Roll the dough tightly from one end to the other. Use gentle pressure to maintain evenness and prevent the filling from spilling out. Then, cut into slices that are about 1 inch thick.

Place the rolls in a greased baking dish, leaving space for them to rise. Bake in the preheated oven for 20-25 minutes or until the tops are slightly golden and the delightful aroma fills your home.

Let cool slightly before serving. Trust me, these rolls are best enjoyed warm, allowing the gooey filling to be just perfect!
