How to Make S’mores Cake | Bite It Quick

1. Preheat your oven to 350°F and grease a 9×13-inch baking pan with butter or non-stick spray.
2. In a large bowl, sift together the flour, cocoa powder, sugar, baking powder, baking soda, and salt to ensure even mixing.
3. In a separate bowl, whisk the eggs, milk, vegetable oil, and vanilla extract until smooth. Gradually add the wet ingredients to the dry ingredients, stirring until just combined.
4. Slowly pour in the boiling water, stirring carefully; the batter will be thin. Pour the batter into the prepared pan and bake for about 30-35 minutes or until a toothpick inserted in the center comes out clean.
5. While the cake bakes, mix 1 cup of graham cracker crumbs with melted butter until crumbly; set aside.
6. Once the cake is done, remove from the oven and immediately sprinkle the mini marshmallows evenly over the top. Return to the oven and bake for an additional 3-5 minutes until marshmallows puff and turn golden.
7. Remove from the oven and quickly sprinkle chopped chocolate over the marshmallows, letting the heat melt the chocolate slightly.
8. Sprinkle the remaining 1/2 cup graham cracker crumbs over the top to add a crunchy texture.
9. Allow the cake to cool for at least 20 minutes before slicing and serving to let the marshmallow topping set nicely.

Tips for the Best Results

• Use fresh cocoa powder for the richest chocolate flavor.
• Don’t overmix the batter to keep the cake light and fluffy.
• Watch the marshmallows closely during the last bake—they brown fast.
• For extra gooeyness, add a layer of chocolate chips under the marshmallows.
• Let the cake cool slightly before cutting to prevent marshmallow sticking.

Storage and Reheating

Store leftover s’mores cake in an airtight container in the refrigerator for up to 4 days. Keep it covered to prevent the marshmallow topping from drying out.

To reheat, warm slices in the microwave for about 15 seconds or until soft and gooey again. Avoid overheating to keep the marshmallows from toughening.

Frequently Asked Questions

Can I use a different type of chocolate for this s’mores cake?

Absolutely! Milk chocolate or dark chocolate works well depending on your taste preference. Just chop it finely so it melts evenly over the marshmallows.

Is it possible to make this cake gluten-free?

Yes, substitute the all-purpose flour with a gluten-free baking blend. Make sure your baking powder is gluten-free, too, for the best results.

Can I prepare this cake ahead of time?

Yes, you can bake the cake base a day in advance and add the marshmallows topping right before serving. This keeps the marshmallows fresh and gooey.

What’s the best way to cut the cake without sticking?

Use a sharp knife warmed under hot water and wiped dry before slicing. This helps cut cleanly through the marshmallow layer without sticking.
