In a medium saucepan over medium high heat, combine the heavy cream, cocoa powder, sugar and salt. Bring to a boil while whisking to dissolve the cocoa and sugar.

Put the dark chocolate morsels in a large bowl. Once the cocoa mixture has reached a boil, remove from heat and pour over the dark chocolate morsels. Let sit for 5 minutes, then whisk until smooth. Add the whole milk, vanilla extract and raspberry liquor and whisk to combine. Chill for at least 2 hours.

Freeze the chilled mixture in an ice cream machine according to manufacturer's instructions. While the ice cream is churning, place a large bowl in the freezer. Once ice cream is done, use a spatula to layer the ice cream with drizzles of raspberry puree and brownie chunks.

Freeze for 2-3 hours before serving.

In a medium saucepan over medium heat, melt the dark chocolate morsels and butter, whisking occasionally. Once melted, remove from heat and whisk in sugar and salt. Whisk in the eggs one at a time until incorporated. Add the vanilla extract. Add the flour and fold in gently.

Pour batter into the prepared baking pan and bake for 30-35 minutes until edges are set. Let cool to room temperature, then remove from pan and chill completely in the fridge for several hours. Break brownies into small chunks and keep cold.

Use a food processor or blender to puree all ingredients. Pass mixture through a mesh strainer to remove seeds. Chill for at least 2 hours and keep cold.
