1. To make the shortcake dough, mix baking mix, melted butter, and heavy cream in a large bowl. Roll the dough into walnut-size balls (if you're doing this well before the party, refrigerate them until dessert time).
2. At the cookout, flatten and shape a dough ball onto one end of a stick as shown so that it's about 1/4 inch thick, then roast it over a fire pit or charcoal grill until it's golden and cooked through.
3. Crumble the shortcake into a bowl and top with strawberries, sugar, and whipped cream.
