Prep: Preheat your oven to 350℉. Spray a 10-inch oven-safe skillet or baking dish with nonstick spray.
Make the Batter: Melt the butter in a large mixing bowl. Whisk in the milk and vanilla, then the sugars. Add the salt, espresso powder, flour, baking powder, cocoa powder, and chocolate chips. Fold everything together with a silicone spatula until just combined. Don't over mix. Spread the batter evenly into the prepared pan.
6 tbsp salted butter, 1/2 cup milk, 1 and 1/2 tsp vanilla extract , 1/4 cup light brown sugar, packed, 1/2 cup granulated sugar , 1/4 tsp salt, 2 tsp DeLallo Instant Espresso Powder, 1 cup all-purpose flour, spooned & leveled or weighed out , 2 tsp baking powder, 1/4 cup cocoa powder, 3/4 cup semi-sweet chocolate chips
Add the Topping: Sprinkle the brown sugar and then the cocoa powder over the batter. Don't mix them in. Pour the hot water over the top. Don't stir it in! This is what will create the lava cake like layer on bottom.
1 cup light brown sugar, packed, 3 tbsp cocoa powder, 1 and 1/2 cups very hot water
Bake: Bake for 33 to 39 minutes. The cobbler will be bubbly and a little crinkly around the edges. It will have a slight jiggle when you move the pan, and a toothpick inserted into the center will pull out some moist crumbs. Let the cake rest for 10-15 minutes before serving.
Serve & Store: Serve warm with a scoop of vanilla ice cream or whipped cream. This is best fresh from the oven. But, leftovers can be cooled to room temperature and stored, covered with foil or plastic wrap, in the fridge for 2-3 days.
