How to Make Chocolate Caramel Marshmallow Ooey Gooey Cake
-
Preheat Oven: Start by setting your oven to 350°F (175°C). This warms up your space and ensures an even bake. Don’t forget to grease your 9×13-inch baking dish to prevent sticking!
-
Combine Ingredients: In a large mixing bowl, mix the chocolate cake mix, eggs, and melted butter. Stir until everything is well combined. The batter should be smooth and slightly thick.
-
Press into Dish: Spread the cake batter evenly into the prepared dish. Use a spatula to create a nice, even layer that will serve as the base for your ooey-gooey goodness.
-
Bake the Base: Place the dish in the preheated oven and bake for 15 minutes. You want the base to be set but not fully baked; it should still be a bit gooey in the center.
-
Add Sweetened Condensed Milk: Remove the dish from the oven and pour the sweetened condensed milk generously over the warm cake base. This will create a delightful, creamy layer underneath!
-
Drizzle Caramel: Spoon the caramel sauce over the condensed milk layer, ensuring it’s evenly distributed. Follow this by sprinkling the mini marshmallows and chocolate chips all over the top.
-
Final Bake: Return the dish to the oven and bake for an additional 20–25 minutes. Watch for the marshmallows to turn a golden brown color, indicating they’re deliciously toasted while the center remains gooey.
-
Cool & Serve: Allow the cake to cool slightly before dusting with powdered sugar if desired. Serve warm, and get ready for a flavor explosion!
Optional: Add chopped nuts for a delightful crunch!

Chef's Helpful Tips
- When making Chocolate Caramel Marshmallow Ooey Gooey Cake, ensure your butter is fully melted to prevent lumps in your batter and achieve a smooth consistency.
- One common mistake is overmixing the cake batter; mix just until combined to maintain a tender texture.
- To achieve the ultimate gooeyness, consider slightly underbaking the base before adding the layers, as it will continue to cook while topped with marshmallows and chocolate chips.
- Keep a close eye on the final bake and remove the cake when the marshmallows are golden brown; this ensures the perfect balance of textures without drying out the center.
Chocolate Caramel Marshmallow Ooey Gooey Cake Recipe FAQs
What should I look for when choosing a chocolate cake mix?

Also, checking the expiration date ensures that you’ll have the best results in terms of flavor and texture.
How long can I store leftover Chocolate Caramel Marshmallow Ooey Gooey Cake?

What if my marshmallows don't turn golden brown?
If your marshmallows remain pale, it may be due to an oven that isn’t hot enough or baking for too short a time. Ensure you preheat your oven correctly and keep an eye on the cake during the final bake. If they still don’t brown, use a kitchen torch to lightly roast them for a few seconds, but be careful not to burn them!
