Instructions:
- Grease a loaf pan (or bundt pan) with butter and set aside.
- In a medium bowl, crush the Maria Biscuits into small pieces and set aside.
- In a separate large bowl, use a hand mixer to whip the heavy cream on high speed until firm peaks form.
- Fold in the sweetened condensed milk and the crushed biscuits until fully combined.
- Pour the mixture into the prepared pan and place in the freezer for at least 4 hours, or overnight.
- For the thick chocolate sauce: Whisk together the milk, sugar, cocoa powder, and cornstarch in a small saucepan. Bring to a boil, then reduce heat and simmer for 2 minutes. Add the butter and vanilla extract and stir until the butter has melted. Serve warm.
- For the thin chocolate sauce: Whisk together the milk, sugar, cocoa powder, and cornstarch in a small saucepan. Bring to a boil, reduce heat, and simmer for 2 minutes. Serve warm.
- When ready to serve, remove the pan from the freezer. If using a loaf pan, scoop directly into bowls. If using a bundt pan, briefly dip the pan into a large bowl of hot water (do not submerge) to loosen, then flip onto a serving dish and cut into slices.
- Drizzle generously with warm chocolate sauce and serve immediately.
Notes: Both chocolate sauces work beautifully with this recipe — the thick sauce is rich and pudding-like, while the thin sauce pours easily over each scoop. Make one or both! Chocolate Bolacha Maria is a delicious variation if you can find it.
