Brookie Slice

This Brookie slice unites two of our favourite things. It starts with a chocolate chunk cookie dough that is baked in to the base. Then a gooey brownie is added on top with marshmallows, peanut butter and coconut for a textural overload. The result is a delight of different textures and flavours that you can swap for your favourite things.

A close up shot reveal three pieces of Brookie slice that have been stacked on top of each other. The shot reveals the cookie base, the brownie centre with peanut butter and chocolate and the marshmallow topping.

This Brookie Slice is a whānau favourite. I don't always get on board with food trends but a slice that combines chocolate chip cookies and brownie is always going to be good. This is such a good recipe to make with tamariki (children) too! Me tākaro tātou (let's play)!

Ingredient tips for the Brookie Slice:

A round wooden board sits on a rustic cloth, on a wooden table. On the board is an array of small vintage plates and vases. Ingredients are added to each one, in view are salt, vanilla, mini marshmallows, almond butter, butter, chocolate, sugar and coconut.
  • Butter: I prefer salted pata (butter) because of the deep flavour but unsalted works. 
  • White sugar: I use huka one (caster sugar) in this recipe but if you prefer huka hāura (brown sugar), go for it.
  • Flour: Plain or high grade flour both work in this recipe.
  • Nut Butter: I add this on to the base and the topping because I am addicted to pata pīnati (peanut butter) but it can be omitted completely if you want.
  • Chocolate: I prefer tiakarete parauri (dark chocolate) but use what you love.
  • Eggs: I always use free-range hēki (eggs) but use what you have.
  • Cocoa: I used to be a big advocate of only using dutch processed cocoa but the price has hiked up these days so use what you have.
  • Marshmallows: Both mini or chopped normal sized ones work for the topping but they are not your vibe, don't use them.
  • Coconut: The kokonati (coconut) on top is just a textural addition and can be omitted if you want.

EXPERT ADVICE:

Take the time to whip the pata (butter) and huka (sugars) for the specified time when making the biscuit base. This will ensure a nice rise to the slice and give the sugars time to dissolve into the butter.

STEP BY STEP INSTRUCTIONS FOR THE BROOKIE SLICE:

Note: The full recipe card with the full list of ingredients, instructions and step by step video are found at the bottom of this page.

9. Add the Dry Ingredients:

Stir it with a whisk just until it is all incorporated and no more. 

10. Add it to the Biscuit Base:

Pour it on top of the paparanga pihikete (biscuit layer) and smooth it out.

A vintage baking tin is lined with brown baking paper. In it is the unbaked brownie part of the brookie slice. It has chunks of chocolate and almond butter all over the top. Naomi is adding more nut butter with a teaspoon and it is dripping off. A wooden table is in the background.

11. Decorate the top of the Brookie Slice: 

Then add the remaining tiakarete (chocolate) and pata nati (nut butter), dividing it evenly on top. 

Sprinkle over the kokonati (coconut) and māngohe (marshmallows) until the slice becomes a textural explosion.

A close up shot reveals the brookie slice topping that has been baked. There is chunks of dark chocolate, shredded coconut, cookie crumbs and toasted pink and white marshmallows.

12. Bake the Brookie Slice:

Bake in a 160 degree oven for 25 minutes until golden and glorious.

Remove it from the oven and allow it to sit for 10-15 minutes in the tin before slicing in to delicious pieces.

Three pieces of Brookie slice have been stacked on top of each other. The shot reveals the cookie base, the brownie centre with peanut butter and chocolate and the marshmallow topping. There are coconut and cookie crumbs all over the board that the brookie slice is on.

Store the Slice:

This will keep well in a sealed container for up to a week.

But wait, there's more...
