Melt each of the chocolates in a separate microwavable bowl. Each can take up to 2minutes to melt. Check and stir frequently (about every 30 seconds) as chocolate can easily burn.
Stir until completely melted and smooth.
Alternating between the two types of chocolate – spoon the melted chocolates onto your prepared baking sheet and carefully spread out into a 14 x 10-in. rectangle.
Swirl the chocolates together to create a marbled effect.
Scatter almonds and dried cranberries evenly over chocolate.
Let stand at room temperature until firm and set (or refrigerate for 1 hour to set).
Break into large pieces and enjoy!
Notes
Keep in an airtight container at cool room temperature or refrigerate up to 1 week.
