In a large bowl, add the cookies, the warm milk and let them soak for 2 minutes.
After this time has passed, mix everything very well until the cookies are completely dissolved.
Add the unsalted butter at room temperature and mix everything very well until combined.
Next, add the baking powder and mix gently.
Transfer all this batter to a baking pan greased with butter and wheat flour and spread it out.
Add the chocolate truffles, spreading them over the batter.
Take to a preheated oven at 180° C (350° F) and bake for 40 minutes.
In a medium bowl, add the semi-sweet chocolate.
Place it in the microwave on high power and melt it in 30-second intervals, always stirring in between until fully melted.
Next, add the whipping cream and mix everything very well until smooth.
After the cake has baked, drizzle the mixture we prepared all over it and spread it out.
Finally, add chocolate sprinkles to taste.
Serve.
