01 -
Heat your oven to 350°F (175°C) and line an 8x8-inch pan with parchment or give it a good coating of butter.
02 -
Grab a medium bowl and mix your melted butter, white sugar, eggs, and vanilla until they're nicely combined.
03 -
Gently fold the flour and salt into your wet mixture. Don't stir too much, just until everything's mixed together.
04 -
Pour your batter evenly into the pan and pop it in the oven for about 20 to 25 minutes. It's done when a toothpick comes out with just a few crumbs stuck to it.
05 -
Let the brownies cool all the way down in the pan. After they're totally cool, cut them into 12 equal squares.
06 -
Slowly melt your white candy melts or chocolate chips in the microwave or using a double boiler until they're smooth and runny.
07 -
Place a big marshmallow on top of each brownie square.
08 -
Drizzle the melted white chocolate over each marshmallow, letting it run down the sides to make the ghost shape.
09 -
While the chocolate's still soft, stick mini chocolate chips on to make eyes and a mouth for each ghost.
10 -
Wait until the white chocolate hardens completely before you serve your spooky treats.
