Monster Mash Brownies

Nick’s favorite thing…

I love how fun these are to make. They’re made of my fudgy chocolate brownie recipe, but more about that below! What I love most about these is how creative you can be. You can use any candies you like, and you could use this same recipe for different holidays too. Not just Halloween. Heart-shaped message valentines candy anyone?

What do Monster Brownies taste like?

My fudgy brownies are a chocolate lover’s dream! So easy to make, a one-bowl recipe which means they’re easy enough for kids to make. They slice easily, and they’re perfect on their own too without the frosting and candies!

What are the ingredients I need for the Monster Brownies?

All-purpose flour – also known as plain flour.

Cocoa powder – I used unsweetened cocoa powder.

Granulated sugar – this is also called white sugar in some countries. Caster sugar will also work.

Unsalted butter – make sure your butter is slightly cooled once melted.

Dark chocolate – I used Nestle Buttons.

Eggs – I used large eggs.

White and dark chocolate chips – I used the nestle brand ones.

American Buttercream FrostingI have a really great recipe for this that you can grab here! It’s great for cupcake, cakes and buttercream decorations!

Milk – I used cow’s milk but almond milk will work too.

Food gel – I used the chef master brand of food gel.

Liquorice – I just used a roll, but use anything you can find that’s similar.

My Top Tips!

  • Have fun with it! Use your imagination and come up with whichever scary monster you like.
  • These are a great option for other holidays too. Use the brownies as a blank canvas ir even just on their own!

amazing recipe, fun but not so easy. Frosting can be a little challenging, I will try to do them this Halloween.

Hi Arcadio! I understand decorating doesn’t come naturally to everyone. It certainly didn’t to me in the beginning. I’m glad you loved the recipe though! N x

Why do you have a link to save this to pinterest on your recipe here if you report those who do it as copyright infringers?
