Start by greasing a 22cm aluminum cake pan with unsalted butter softened to room temperature, add the chocolate sprinkles, and spread them evenly across the entire pan.
Add the sweetened condensed milk and set the cake pan aside.
In a large bowl, add the eggs, the refined sugar and mix until the sugar is completely dissolved.
Add the vegetable oil, the milk and mix again until well combined.
Next, add the wheat flour, the cocoa powder and mix until smooth and well combined.
Add the baking powder and gently mix to incorporate.
Pour all the batter into the cake pan we prepared earlier.
Take the dessert to a preheated oven at 180° C (350° F) and bake it for 45 minutes.
Serve.
