Ingredients

For the Cookie Crust

• 125g chocolate chip cookies

• 60g softened salted butter

• ¼ tsp ground cinnamon

For the Brownie Filling

• 70g salted butter

• 70g 55% dark chocolate

• 100g caster sugar

• 1 large egg

• 1 tsp vanilla extract

• 15g unsweetened cocoa powder

• 40g plain flour

For the Topping

• 100g mini marshmallows

Method

Step 1 – Make the Cookie Base

Preheat your oven to 170°C (150°C fan) and lightly grease or line a pie dish.

Blitz the chocolate chip cookies in a food processor until they resemble fine crumbs. Stir through the softened butter and ground cinnamon until the mixture resembles wet sand.

Press the crumb mixture firmly into the base and slightly up the sides of your pie dish using the back of a spoon or the base of a glass. Set aside while you prepare the filling.

Step 2 – Make the Brownie Filling

Place the butter and dark chocolate into a heatproof bowl and melt gently over a pan of barely simmering water or in short bursts in the microwave. Stir until smooth and leave to cool for a couple of minutes.

Meanwhile, whisk together the caster sugar and egg until the mixture becomes pale, thick, and fluffy.

Slowly pour the melted chocolate mixture into the egg mixture while whisking continuously. Stir in the vanilla extract.

Sift in the cocoa powder and plain flour, then gently fold everything together until no streaks of flour remain.

Pour the brownie batter into the prepared cookie crust and smooth the surface.

Step 3 – Bake

Bake for 20 minutes.

As soon as the pie comes out of the oven, gently crack the top of the brownie with the back of a spoon. This helps create little pockets for the marshmallows to settle into.

Scatter the mini marshmallows evenly over the top, gently pressing them into the warm brownie.

Use a kitchen blowtorch to toast the marshmallows until golden, or return the pie to the oven for 5–10 minutes until the marshmallows are soft and lightly toasted.

Step 4 – Serve

If serving warm, allow the pie to rest for 20 minutes before slicing. The brownie will still be deliciously gooey and the marshmallows beautifully stretchy.

For a firmer, extra-fudgy texture, allow the pie to cool for one hour before refrigerating for at least 4 hours. Chilling makes it much easier to slice and intensifies the chocolate flavour.

Tips for the Best S'mores Brownie Pie

• Use good-quality 55% dark chocolate for a perfectly balanced brownie that isn't overly sweet.

• Don't overbake the brownie—it should still have a slight wobble in the centre when it comes out of the oven.

• Chilling overnight produces beautifully clean slices with an intensely fudgy centre. Just remember to grease your knife to help slice through the matshmallows.

• Add crushed digestive biscuits, graham crackers, or chocolate chunks over the marshmallows for extra texture.

• Serve with vanilla ice cream, whipped cream, or fresh berries for the ultimate dessert.

Frequently Asked Questions

Can I make S'mores Brownie Pie ahead of time?

Yes! This dessert is ideal for making a day ahead. Simply refrigerate until ready to serve.

Can I freeze it?

Absolutely. Freeze the brownie pie (without the marshmallow topping if possible) for up to three months. Defrost overnight in the fridge before reheating or serving.

Can I use milk chocolate?

You can, but the finished pie will be much sweeter. A chocolate with around 55% cocoa solids gives the best balance against the sweet marshmallows and cookie crust.

How do I get clean slices?

For neat slices, chill the pie for at least four hours, then use a sharp knife dipped in hot water and wiped clean between each cut.

Serving Suggestions

This S'mores Brownie Pie is delicious on its own, but it's even better served with:
