Ingredients You’ll Need
To make a S’mores Loaf Cake, gather:
- 1 ½ cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ½ cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- ½ cup buttermilk
- ½ cup milk
- 1 cup semi-sweet chocolate chips
- 1 cup mini marshmallows
- ½ cup graham cracker crumbs
- Optional: chocolate ganache or drizzle for topping
How to Make Mouthwatering S’mores Loaf Cake
Step 1: Prepare the Oven and Pan
Preheat your oven to 350°F (175°C). Grease a loaf pan and line it with parchment paper for easy removal.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
Step 3: Cream Butter and Sugar
In a large bowl, beat the softened butter and granulated sugar until light and fluffy. Add eggs, one at a time, beating well after each addition. Stir in vanilla extract.
Step 4: Combine Wet and Dry Ingredients
Alternate adding the flour mixture and buttermilk to the butter mixture, beginning and ending with the flour. Mix until just combined. Stir in milk and chocolate chips.
Step 5: Assemble the Loaf Cake
Pour half of the batter into the prepared loaf pan. Sprinkle a layer of graham cracker crumbs and mini marshmallows over the batter. Add the remaining batter on top, then top with more marshmallows and graham cracker crumbs.
Step 6: Bake the Cake
Bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean (marshmallows may melt, but that’s part of the magic!). Allow the cake to cool slightly in the pan before removing.
Step 7: Optional Topping
For an extra decadent touch, drizzle melted chocolate or chocolate ganache over the cooled loaf. Serve slices with a glass of milk or coffee for the ultimate indulgence.
