How to Make S’mores Cake | Bite It Quick

1. Preheat your oven to 350°F and grease a 9-inch round cake pan, then line the bottom with parchment paper for easy removal.
2. In a large bowl, sift together the flour, baking powder, baking soda, salt, and cocoa powder for an even chocolate base.
3. In a separate bowl, beat the sugar and eggs until light and fluffy. Add the buttermilk, oil, and vanilla extract, mixing well.
4. Gradually add the dry ingredients to the wet ingredients, alternating with boiling water, stirring gently until smooth and fully combined.
5. Pour half of the batter into the prepared pan. Dollop the marshmallow fluff over the batter, spreading gently but leaving some texture. Pour the remaining cake batter over the marshmallow layer, smoothing the top.
6. Mix the crushed graham crackers, melted butter, and chocolate chips together to create the crumble topping, then sprinkle evenly over the cake.
7. Bake for 35 minutes or until a toothpick inserted near the edge comes out clean (avoid the marshmallow center). The top should be golden and slightly crispy.
8. Allow the cake to cool in the pan for 15 minutes before transferring it to a wire rack to cool completely. This helps the marshmallow set perfectly inside.
9. Slice and serve your s’mores cake with a scoop of vanilla ice cream or a drizzle of chocolate sauce for extra indulgence.

Tips for the Best Results

• Use room temperature ingredients to ensure smooth batter and even baking.
• Be gentle when layering the marshmallow fluff so it stays distinct inside the cake.
• Don’t overbake; the marshmallow layer should remain gooey and soft.
• For extra chocolatey flavor, use a high-quality cocoa powder and semi-sweet chocolate chips.
• Toast the graham crackers lightly before crushing for a deeper, nutty flavor in the crumble topping.

Storage and Reheating

Store the s’mores cake in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days. Keep it covered well to prevent the marshmallow from drying out.

You can freeze the cake for up to 2 months by wrapping it tightly in plastic wrap and aluminum foil. Thaw overnight in the refrigerator before serving. Reheat slices gently in the microwave for 10-15 seconds to revive the gooey marshmallow texture.

Frequently Asked Questions

Can I use marshmallows instead of marshmallow fluff?

Yes, you can use mini marshmallows instead of marshmallow fluff by layering them between the cake batter. They may melt differently, so expect a slightly different texture but still delicious results.

Is this cake suitable for kids?

Absolutely! The s’mores cake is a fun and sweet dessert that kids love. Just be mindful of any allergies to ingredients like dairy or gluten.

Can I make this cake gluten-free?

To make it gluten-free, substitute the all-purpose flour with a gluten-free baking blend and use gluten-free graham crackers. The texture may vary slightly but will still be tasty.

How do I get the marshmallow layer gooey but not runny?

Layer the marshmallow fluff carefully and avoid overbaking the cake. Baking near the center toothpick test helps keep the marshmallow gooey and soft without it becoming too liquid.
