Cooking Time & Tips For Marshmallow Brownie Slice
Preparation for Marshmallow Brownie Slice can be both quick and enjoyable. A quick approach means you’ll get to indulge in this delightful dessert in just under an hour, while a slower preparation allows the flavors to meld together beautifully.
To ensure your brownie slice turns out perfectly, consider these practical tips:
- Use Quality Chocolate: The flavor of your dessert largely depends on the chocolate you choose, so opt for high-quality milk chocolate for the topping.
- Don’t Overmix: When combining your dry ingredients with wet, make sure to fold gently. This keeps your brownies from becoming dense.
- Cool Properly: Allow your brownies to cool adequately before adding the topping; this will prevent it from melting and blending into the brownies.
Step-by-Step Directions

- Preheat your oven to 150°C (fan bake) and line a 20 cm square tin with baking paper. This step is crucial for easy removal and clean slicing later.
- Melt the butter in a large microwave-safe bowl until fully liquid. The warm aroma of melting butter will fill your kitchen, making your mouth water in anticipation.
- Stir in the caster sugar, vanilla essence, and eggs until glossy and smooth. Watch as the mixture transforms into a beautiful consistency that’s begging to be baked.
- Sift in the cocoa powder, plain flour, and baking powder; fold until just combined. Be gentle here—overmixing can lead to heavy brownies.
- Spread the batter evenly into the prepared tin, smoothing the top with a spatula for an even bake, and bake for approximately 25 minutes.
- After the timer goes off, cool the brownies in the tin for 15 minutes. This patience ensures the right texture once set.
- For the topping, melt the milk chocolate and coconut oil in a heatproof bowl, stirring until it’s completely smooth and silky. The aroma of chocolate adds to the comfort of baking.
- Stir in the marshmallows, coating them in chocolate, creating a beautiful concoction that’s irresistible.
- Pour the chocolate-marshmallow topping over the cooled brownie base, making sure to spread it evenly.
- Refrigerate for at least 2 hours. This step allows the topping to set perfectly, creating a delicious contrast with the warm brownie.
- Once set, lift from the tin using the baking paper, slice into squares, and serve. Watching others enjoy your creation will be the cherry on top of your baking adventure!
