In a saucepan, add the strawberries, sugar, Lemon juice and Lemon zest.
Let it simmer over medium heat.
Stir frequently mashing the strawberries as you stir.
After 5min, mix the cornstarch with the water (aside) and then add it to the saucepan.
Continue stirring frequently. Cook for another 5min, or until the jam starts to thicken.
When it is done, remove it from the heat ant let it cool down for 5min.
Take out the brownie/ice cream from the freezer and spread an even layer of peanut butter over the ice cream layer, then spread the strawberry jam. Place in the freezer for 1 or 2 hours.
Lift the ice cream slab out of the pan using the parchment. Working quickly, cut into square bars or rectangles. Insert a popsicle stick into one end of each bar. Return to the freezer until frozen solid.
Melt the chocolate and coconut oil together in the microwave until melted and smooth. Let cool 10 minutes. Remove the bars from the freezer and drizzle or dip them in chocolate.
