Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish or line it with parchment paper.
In a large mixing bowl, cream together the unsalted butter, brown sugar, and granulated sugar until light and fluffy.
Add the eggs and vanilla extract to the mixture, beating well until combined.
In a separate bowl, whisk together the all-purpose flour, rolled oats, baking soda, and salt.
Gradually add the dry ingredients into the wet ingredients, mixing just until combined. Do not overmix.
In a microwave-safe bowl, melt the semi-sweet chocolate chips in 20-second intervals, stirring after each interval, until smooth and fully melted. Set aside.
Spread the oatmeal batter evenly into the prepared baking dish.
Drizzle the melted chocolate over the top of the batter. Use a butter knife to gently swirl the chocolate into the batter, creating a marbled effect.
Bake in the preheated oven for 22-25 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out mostly clean (a few crumbs are fine).
Let the bars cool in the dish for 10 minutes, then transfer them to a wire rack to cool completely before cutting into squares or bars.
Serve and enjoy your delicious Oatmeal Marble Bars!
