Brookie Muffins (Brownie + Cookie in One)

Every family has its Great Dessert Argument, and in ours it ran for years. My younger brother was a brownie man — fudgy, dark, no toppings, no debate — while I was firmly team cookie, all golden edges and melting chocolate chips. Birthdays were a negotiation. Whoever was baking quietly won, and the other one sulked into their slice.

Then one year I was roped into making something for my niece’s school bake sale, panicking the night before about what would actually sell, and I did the lazy, obvious thing: I poured brownie batter into muffin cups and dropped spoonfuls of leftover cookie dough on top. They came out as these tall, craggy muffins — fudgy brownie underneath, chewy cookie on top — and they sold out before the table was even properly set. My brother ate three “for quality control.” The argument, after all those years, was finally over.

That’s the whole charm of a brookie: it refuses to choose. You get the deep, gooey richness of a brownie and the buttery, chocolate-chip chew of a cookie in the same bite, baked into a neat tulip-wrapped muffin that’s made for sharing — a lunchbox, an office desk, a party table, or a bake sale that needs a guaranteed sell-out.

Why you’ll love these brookie muffins

Two desserts, no compromise

A rich, fudgy brownie base and a chewy chocolate chip cookie top, baked together — so nobody has to pick a side. Every muffin has both textures in one.

Bakery-tall and shareable

Baked in tulip parchment cups, they rise into proper café-style muffins that lift out cleanly and look impressive with zero decorating. Perfect for handing round.

Gooey in the middle

Pulled from the oven while the brownie centre is still soft, they stay fudgy and molten inside under that golden cookie crust — best of all slightly warm.

Ingredients

You’re really making two easy batters — a quick cookie dough and a fudgy brownie — from everyday baking staples. Here’s everything laid out:

For the cookie dough: melted butter, brown and white sugar, an egg, vanilla, flour, baking powder, salt and chocolate chips.

For the brownie batter: butter, dark chocolate, eggs, sugar, flour, cocoa, salt and a few more chocolate chips.

How to make brookie muffins

1. Line the tin. Line a 12-hole muffin tin with tulip parchment cups and heat the oven to 180°C / 350°F.

2. Make the cookie dough. Whisk the melted butter with both sugars, then the egg and vanilla. Stir in the flour, baking powder and salt, then fold in the chocolate chips. Set aside.

   

3. Melt for the brownie. Gently melt the butter and dark chocolate together — in short microwave bursts or over a pan of simmering water — and let it cool slightly.

4. Whisk the brownie base. Beat the eggs and sugar until pale and thick, then stir in the melted chocolate mixture.

   

5. Finish the brownie batter. Fold in the flour, cocoa and salt, then the chocolate chips, until just combined.

6. Layer the bottom. Press a small ball of cookie dough into the base of each parchment cup.

   

7. Add the brownie. Spoon the brownie batter over the cookie layer, filling each cup to about three-quarters full.

8. Top with cookie dough. Dot small pieces of the remaining cookie dough over the brownie batter.

   

9. Bake. Bake for 18–20 minutes, until the cookie tops are golden and the brownie is set with a soft, fudgy centre. Cool in the tin before lifting out.

Tips for perfect brookies

Don’t overbake: pull them while the centre still looks slightly soft — the fudgy middle sets as they cool. Overbaking turns the brownie cakey.

Keep the cookie dough chunky on top: rough little pieces give that craggy, golden bakery look rather than a smooth lid.

Cool before lifting: let them set in the tin for at least 15 minutes so the soft brownie firms up enough to hold its shape.

Warm to serve: a few seconds in the microwave brings back that molten-chocolate, fresh-baked moment.

Make ahead, store & freeze

Make ahead: both batters can be made a few hours ahead and kept chilled; assemble and bake when you need them fresh.

Store: keep in an airtight container for up to 3 days — they’re brilliantly fudgy on day two.

Freeze: cool completely, wrap individually and freeze for up to 2 months. Thaw at room temperature or warm briefly to bring back the gooey centre.

Easy variations

• Triple chocolate: use a mix of dark, milk and white chocolate chips throughout.
• Nutty: add chopped walnuts or pecans to the brownie batter, bakery-style.
• Stuffed: push a square of chocolate or a little spoon of hazelnut spread into the brownie centre.
• Shortcut version: use a boxed brownie mix for the base and just make the cookie dough — ideal for a bake sale.
• More chocolate fixes: if you love a gooey bake, our thick chocolate chip cookies are the natural next one to try.

Brookie muffin FAQ

What is a brookie?

A brookie is a brownie and a cookie baked together — the best of both in one bite. In these muffins, a fudgy chocolate brownie is layered with chocolate chip cookie dough, so you get a rich, gooey brownie middle and golden, chewy cookie on top. If you can never decide between the two, brookies are the answer.

Why bake them in tulip parchment cups?

Tulip cups hold the soft batter, give the muffins their tall bakery shape, and make them easy to lift out and serve with no greasing or sticking. You can use regular muffin cases or a well-greased tin instead, but the parchment tulip wraps give that café-style look and stop the gooey edges sticking.

How do I know when they’re done?

The cookie tops should be golden and just set, and the brownie should look baked at the edges but still soft in the centre — a skewer will come out with a few moist crumbs, not wet batter. They firm up as they cool, so don’t overbake them or you’ll lose the fudgy middle.

Can I make brookie muffins ahead or freeze them?

Yes. They keep in an airtight container for up to 3 days and actually taste wonderfully fudgy on day two. You can also freeze them once cooled — wrap individually and freeze for up to 2 months, then thaw at room temperature or warm briefly so the chocolate goes melty again.

Can I use a brownie box mix to make it easier?

Absolutely. If you’re short on time, prepare a boxed brownie mix for the brownie layer and just make the cookie dough from scratch (or use shop-bought cookie dough). The layering and baking stay exactly the same — it’s a great shortcut for a school bake sale or last-minute treat.
