Make the ice cream by placing the coconut milks and coconut sugar in a pot over medium-low heat on the stove. Stir until the sugar has dissolved and no coconut milk clumps remain; let cool. Stir in the vanilla extract and mint extract.
13.5 oz can lite coconut milk, 1 7.4- oz can sweetened and condensed coconut milk, 2 tablespoon coconut sugar, 1 teaspoon vanilla, ½ teaspoon mint extract
Transfer the ice cream mixture to an ice cream machine (see notes for no-churn version) and churn in accordance with manufacturer instructions. Once the ice cream is almost done, add the chocolate chunks and stir to incorporate. Pour the ice cream into a container and place in freezer for at least an hour to harden.
¾ cup chocolate chunks
Prepare the brownies in accordance with the instructions, however, use a 9 x 13 inch baking pan to get thinner brownies. Bake for 17 - 20 minutes until the edges are crispy (we are looking for slightly underdone in the middle so that they will remain nice and fudgy once chilled); let cool them place in freezer for at least 30 minutes to firm up.

To assemble, slice the hardened brownie sheet in half, leaving two 9 x 6.5 inch brownie sections. Turn one of the brownie sections over and scoop ice cream on top. With a flat edged knife, spread the ice cream into a large ice cream block covering the entirety of the brownie. Place the other brownie section on top of the ice cream then place in freezer for another hour to solidify (this makes cutting them much easier.
Slice the brownies into 8 small rectangles. To do this, cut the brownies in half down the long-edge side. Rotate the brownies and make another cut down the middle of the short-edge then cut those halves in half again leaving 8 rectangular sandwiches. Enjoy immediately or store in an airtight container lined with parchment paper in the freezer for up to 2 weeks.
