Spooky Mini Halloween Brownies

These Spooky Mini Halloween Brownies are the ultimate Halloween treat! Rich, fudgy chocolate brownies with a crunchy Oreo biscuit base, topped with creamy chocolate buttercream and fun spooky decorations. Easy to make, deliciously indulgent and perfect for Halloween parties, trick-or-treat celebrations or baking with the kids.

These Spooky Mini Halloween Brownies down an absolute treat with the kids over Halloween. We had a little party after all the trick-or-treating, and I served these up for both the adults and the kids. Needless to say, they didn’t last very long!

Think fudgy, gooey chocolate brownies with a little surprise Oreo biscuit hidden inside, topped with a generous swirl of chocolate buttercream and finished with spooky Halloween decorations. So good!

Fudgy brownies with a surprise Oreo centre

What’s not to love about a chocolate brownie? Add an Oreo biscuit into the mix and you’ve got something even better!

The Oreo gives the brownies a lovely crunchy base, while the brownie itself stays deliciously soft, rich and gooey. Then comes the chocolate buttercream, which adds an extra layer of indulgence.

Perfect for Halloween parties and baking with the kids

We had such a lovely Halloween this year. After a busy evening of trick-or-treating, we had everyone back for a little party. We played the usual Halloween games, including bobbing for apples and put on a movie for the kids.

Of course, no Halloween party would be complete without a few sweet treats!

These brownies were perfect for serving up. They’re easy to make ahead, easy to decorate and just the right size for little hands. They’re also lovely for sharing at Halloween parties, school events or a fun afternoon of baking with the kids.

Make them for any occasion

Although I’ve decorated these with Halloween in mind, the brownie recipe itself is so versatile. You can easily switch up the decorations depending on the occasion.

Try different sprinkles, coloured buttercream or little themed decorations to suit birthdays, Christmas, Easter or any celebration throughout the year.

It’s a lovely little recipe to keep in your baking collection and one you can adapt again and again.

A little balance after Halloween

I have to say, after all the Halloween treats, we definitely needed a little break from the sugar. I’m all about balance, but I think between the trick-or-treating sweets and the party treats, we’d probably consumed enough sugar for a couple of weeks.

We followed it up with a week of no-added-sugar treats, which was a nice change after all the Halloween fun. But that’s what it’s all about, isn’t it? Enjoying the occasions, making memories and having a little fun along the way!


These little brownies are proof that baking doesn’t need to be complicated! The combination of crunchy Oreo, rich fudgy brownie and creamy chocolate icing makes them seriously hard to resist. They’re a lovely one to get the kids involved with too, especially when it comes to decorating! Whether you’re making them for a party, a movie night or just a weekend baking treat, I hope you enjoy them as much as we did. Don’t forget to tag @littleloucooks if you recreate them, I love seeing how you decorate all your bakes.
