Begin by mixing your brownie mix according to its package’s directions and baking them accordingly. Allow to cool completely.

Cut the brownies into rectangles.

Attach Wilton icing tip #5 to the frosting (both black and white). Begin frosting each brownie.

Start with the black frosting. Frost a vertical line along the left-hand side of each brownie. Add small horizontal lines along the original line.

Add black squiggles all around the rest of the brownie.

On the right-hand side of the brownie, add a dollop of white frosting. Finish it off with the “pupil” by adding black frosting to the centre.
