Bake the brownies. Preheat your oven to 350°F (175°C). Prepare brownie mix according to package directions, pour into a greased baking dish, and bake for 20–25 minutes until a toothpick inserted in the center comes out clean. Let cool completely, then cut into 1-inch squares.
Prep the strawberries. Rinse strawberries under cold water, hull them, and pat dry thoroughly with paper towels. Dry strawberries are key - moisture stops the chocolate from sticking!
Assemble the skewers. Thread one brownie square, one strawberry, and one marshmallow onto each wooden skewer. Repeat the pattern until the skewer is filled. Leave 1–2 inches free at the bottom for easy handling. Place finished skewers on a parchment-lined tray.
Melt the chocolate. Add chocolate chips to a microwave-safe bowl. Microwave in 30-second intervals, stirring after each one, until fully melted and smooth (about 1–2 minutes total). Do not overheat.
Drizzle the chocolate. Use a spoon to drizzle melted chocolate generously over each kabob in a zigzag pattern - or dip the top half of each kabob directly into the chocolate for a bolder finish.
Chill and serve. Refrigerate kabobs for 10–15 minutes until the chocolate sets. Serve on a platter, stand upright in a jar, or arrange on a dessert board. Enjoy!
