Step 1: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan or line it with parchment paper for this witchs cauldron brownies recipe.
Step 2: In a large bowl, whisk together the melted butter and sugar until smooth. Add the eggs and vanilla, beating well to ensure a fudgy texture for your witchs cauldron brownies recipe.
Step 3: Sift in the cocoa powder, flour, and salt. Fold gently until just combined; do not overmix, as this witchs cauldron brownies recipe is best when dense.
Step 4: Pour the batter into the prepared pan and bake for 25-30 minutes. Let the brownies cool completely in the pan.
Step 5: Use a 2-inch round cutter to cut circles from the cooled brownies. This is the base of your witchs cauldron brownies recipe.
Step 6: Gently press down the center of each brownie round to create a small well. Pipe green frosting into the well, letting it ‘overflow’ slightly.
Step 7: Top the frosting with green sprinkles and attach small loops of licorice to the sides as handles to finish your witchs cauldron brownies recipe.
