- 3 tablespoons 100% pure cocoa
- 1/2 cup buttermilk
- 1 teaspoon baking soda
- 1 1/2 cups miniature marshmallows

Instructions

- Step 3: Remove the saucepan from heat and pour the hot mixture over the flour mixture. Stir with a spoon until combined.
- Step 4: In a small bowl, mix buttermilk and baking soda together, then pour this into the cake batter. Add miniature marshmallows, eggs, and vanilla extract. Stir until evenly mixed. Note that the marshmallows will not melt completely.
- Step 5: Pour the batter into a sprayed 9 x 13 inch baking pan. Bake for 30 to 35 minutes or until a toothpick inserted in the center comes out clean. Let the cake cool slightly before frosting.
- Step 6: For the frosting, bring 1/2 cup butter, 3 tablespoons cocoa, and 6 tablespoons Coca Cola to a boil in a saucepan. Remove from heat, then stir in vanilla and powdered sugar until the frosting reaches a spreadable consistency.
- Step 7: Optionally mix nuts into the frosting or sprinkle them on top. Spread the frosting evenly over the warm cake.
Tips & Variations
- Adding the optional cinnamon enhances the chocolate flavor and adds warmth to the cake’s profile.
- Use regular Coca Cola for the best traditional flavor; diet or flavored sodas may alter the taste.
- For a nut-free version, simply omit the nuts or use seeds like pumpkin or sunflower if desired.
- If you prefer a richer cake, substitute some of the all-purpose flour with cake flour for a softer crumb.
Storage
Store the cake covered at room temperature for up to 2 days or refrigerate for up to 5 days. If refrigerated, let the cake come to room temperature before serving for best texture. Reheat slices gently in the microwave to soften the frosting if desired.
