Line a large baking sheet with parchment paper.
In a large saucepan over low heat, melt the almond bark until completely smooth.
Pour half (eyeball it) of the melted chocolate into a heatproof bowl.
Add the strawberry cake mix to that half, and stir until combined.
Spread it evenly onto the parchment paper.
Place in the freezer for 5 minutes.
Meanwhile, add the funfetti cake mix to the remaining chocolate.
Remove the pan from the freezer, and spread the funfetti chocolate evenly over the strawberry chocolate.
Decorate with sprinkles.
Allow to set completely, placing in the fridge to speed up the process, if desired, and then break into pieces.
