For the Brigadeiro topping:
Combine Cream and Chocolate Powder: In a small saucepan, pour the cream and add the chocolate powder. Whisk the cream and chocolate powder mixture together over medium-low heat. Ensure the chocolate powder is fully dissolved.
Add Condensed Milk and Butter: Once the chocolate powder is dissolved, add the sweetened condensed milk and butter to the saucepan. Continuously stir the mixture over medium-low heat until it thickens and starts to release from the bottom of the pan, about 5 minutes.
Check Consistency: The Brigadeiro should be thick but still pourable.
Pour over Cake: Once thickened, pour the Brigadeiro all over the Brazilian Carrot Cake evenly.
Let Sit: Allow the cake to sit for a few minutes before serving to allow the Brigadeiro to set slightly.
