Now, we're going to get this into the oven. 350 to about 20 minutes. We want to get nice and toasted in there and then we'll start making that croissant bark.
Time to make our homemade caramel toffee; mix butter, brown sugar, and Uncle Steve shake over medium heat for about three to four minutes until bubbly and combined.
Pour the caramel mixture over the flattened croissants after removing the weight.
We're going to give this another couple minutes in the oven, about two to five at the most, to ensure it heats through and sticks to the croissants.
Add chocolate pieces over the top; the heat should start melting the chocolate, then swirl it in.
Add freeze-dried marshmallows and any additional decorations before refrigerating.
Let it cool down in the fridge, then break it up into pieces to serve.
