Preheat your oven to 350°F (175°C). Grease an 8x8 inch baking pan and line it with parchment paper, leaving some overhang for easy removal later.
Prepare the salted caramel sauce: In a saucepan, heat the granulated sugar over medium heat, stirring constantly with a whisk or wooden spoon until it melts and turns amber in color.
Add the cannabis-infused butter to the melted sugar and stir until the butter is fully incorporated and the mixture is smooth.
Slowly pour in the heavy cream while stirring constantly. Be careful as the mixture will bubble up.
Remove the saucepan from the heat and stir in the sea salt. Set aside to cool slightly.
Prepare the brownie batter: In a mixing bowl, cream together the cannabis-infused butter and granulated sugar until light and fluffy.
Beat in the eggs, one at a time, followed by the vanilla extract.
In a separate bowl, sift together the cocoa powder, all-purpose flour, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Pour half of the brownie batter into the prepared baking pan and spread it out evenly.
Drizzle half of the salted caramel sauce over the brownie batter in the pan.
Pour the remaining brownie batter over the caramel layer and spread it out evenly.
Drizzle the remaining salted caramel sauce over the top of the brownie batter.
Use a knife or skewer to swirl the caramel sauce into the brownie batter to create a marbled effect.
Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
Allow the brownies to cool completely in the pan before slicing into squares.
Serve and enjoy your Cannabis-Infused Salted Caramel Fudge Brownies!
