Preheat oven to 350° F.
In the bowl of a stand mixer, combine the melted butter, brown sugar and granulated sugar until well combined.
Reduce the speed to low and add in the eggs, caramel topping and vanilla, mixing until well combined.
Add the flour, cornstarch, salt and baking soda, mixing until a soft dough forms.
Fold in the mini kisses or chocolate chips until evenly distributed.
Portion out the dough into 1/3 cup portions (a heaping #12 scoop), roll into a ball and place in the center of a large round silicone baking mold. (Because these are blondies, like a brownie, we need the pan for them to keep shape, or else they would spread for daaaaayyys).
Bake at 350° F for 12-14 minutes, until the cookies have flattened, spread and are no longer wet and glossy on the top of the cookie. The edges may have started turning golden brown.
Allow the cookies to cool completely in the silicone mold before removing them.
Once completely cool, make the cloud frosting.
