Brookie Traybake


For everyone who has ever stood at a bakery counter unable to choose between a brownie and a cookie, this one is for you.

I have never understood why we make people pick. A brownie is fudgy and rich and chocolatey, and a cookie is soft in the middle with that slightly chewy edge, and honestly, why not have both in one bite? That is exactly what this traybake is. A goey chocolate brownie base loaded with protein, topped with soft cookie dough that bakes right into it, so every square gives you a little bit of both worlds.

It looks like a long recipe when you first read it, but it really is just two doughs made separately and layered together. And the payoff is worth every step. This keeps beautifully in the fridge for up to a week, or in the freezer for a month, so I always make a full tray and thank myself later.

This recipe is:

  • Vegan & dairy free

  • Gluten free

  • High protein

  • Refined sugar free

  • Made with wholesome, everyday ingredients

Why This Recipe Works

The two layers do very different jobs and that is what makes this so satisfying. The brownie batter uses oat flour and a chocolate plant protein powder along with mashed banana, so it stays moist and fudgy without needing any butter or refined sugar. The cookie dough layer is made from almond flour and peanut butter, blended until it forms an actual workable dough, which is what gives it that soft bakery cookie texture once it hits the oven.

  • Chocolate plant protein powder gives the brownie layer its fudginess and protein boost

  • Ripe bananas add natural sweetness and moisture without any oil

  • Almond flour cookie dough bakes soft instead of crumbly

  • Walnuts and sugar free chocolate chips add crunch and richness in every bite

  • Freezes beautifully, so you always have a treat on standby

How to Make Brookie Traybake (Overview)


Hand holding a gooey chocolate chip cookie bar over a tray of cut bars, with dark chocolate and crumbly golden center close-up.

This comes together in 3 simple steps:

1. Make the Cookie Dough

Blend almond flour, non-dairy milk, vanilla, peanut butter, and sweetener in a food processor or by hand until a soft dough forms. Fold in the chocolate chips.

2. Make the Brownie Batter

Blend the oat flour, protein powder, cocoa powder, flax eggs, bananas, sweetener, milk, and vanilla until completely smooth. Fold in the walnuts and chocolate chips at the end.

3. Layer and Bake

Pour the brownie batter into a lined tray, flatten small discs of the cookie dough over the top, and bake until just set.


Tips for Best Results

  • Flatten the cookie dough balls slightly before placing them on the brownie batter, so they sit evenly across the tray

  • Bake until the centre is almost fully set. It will continue to firm up as it cools

  • Let the tray cool completely before slicing for the cleanest squares

  • Store in the fridge for up to a week or freeze individual squares for longer
