Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish or line it with parchment paper.
In a large bowl, whisk together the flour, cocoa powder, granulated sugar, brown sugar, baking powder, baking soda, and salt.
In a separate bowl, whisk the melted butter, vegetable oil, vanilla extract, eggs, milk, and sour cream until smooth and well combined.
Gradually add the wet ingredients to the dry ingredients and mix until just combined. Be careful not to overmix.
Gently fold in the mini chocolate chips with a spatula.
Pour the batter into the prepared baking dish and spread it out evenly with a spatula.
For the crumb topping, combine 1.5 cups of flour, 0.5 cup cocoa powder, 1 cup granulated sugar, and 1 teaspoon salt in a bowl. Add 0.75 cup (12 tablespoons) melted unsalted butter and mix with a fork until crumbs form.
Sprinkle the crumb mixture evenly over the cake batter.
Bake in the preheated oven for 35–40 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs.
Let the cake cool in the dish for at least 20 minutes before slicing.
Dust the top of the cake lightly with powdered sugar before serving.
