How to Make It
Preheat the oven to 350°F and line a rimmed baking sheet with parchment paper. Spread the flour onto the baking sheet and bake for 5 minutes (this kills any bacteria). Let cool.
Using an electric mixer, beat the butter, brown sugar, and cream cheese on medium-high until light and fluffy, 2 to 3 minutes. Beat in the milk and vanilla.
Reduce mixer speed to low. Pick up the parchment paper with the flour and fold it to create a funnel. Gradually pour the flour into the mixing bowl and beat until just combined, scraping down the sides of the bowl as necessary. Add the salt and mix until combined.
Stir in the chopped chocolate with a rubber spatula. Scoop onto ice cream cones and top with chocolate sauce, whipped cream, sprinkles, or cherries.
