Prepare brownie mix as directed, bake in a 9x13 pan and let cool completely.

Make the strawberry icing next, by using a mixer to cream together the softened butter and jam in a medium bowl, about 2 minutes.

Add the powdered sugar, one cup at a time till you reach desired consistency. If too dry, add a little milk or a dab more of strawberry jam.

After brownies are cooled, use the heart shaped cutter to carefully cut out two brownie heart shapes. (see above photo for reference) Transfer to wax paper.

Use icing in a bag to pipe two wide outlines around outside edges of one brownie and then carefully spoon some strawberry jam in the center, then put the other brownie heart shape on top

Transfer the stacked brownie cake to a wire rack with wax paper underneath (for easy cleanup.)

Melt your chocolate as directed on the package, using the microwave, or a double boiler until a pourable, thin consistency. Spoon or carefully pour melted chocolate over the stacked brownie cake until covered (or maybe you want just a "poured over-the-top" look, dripping off the edges slightly)

While chocolate is still wet, decorate your brownie cake with sprinkles. If desired, melt some white chocolate and drizzle over the top.

Before serving, microwave the brownie cake for 15-20 seconds to softened chocolate and give the inside a lava-cake experience!
