Monster Brownies

Posted by

If you're looking for something cute to bake for Halloween these Monster Brownies are it! I had such a fun time creating these Monster Brownies for ColorKitchen using their amazing all natural plant based food dyes. You can make these Monster Brownies funny, spooky or just plain weird - which I absolutely love. 

Monster Brownies | Makes 14 Brownies


  • 284 g. organic sugar
  • ½ tsp. organic vanilla bean
  • 57 g. organic Dutch cocoa
  • 57 g. organic dark chocolate chunks
  • ½ cup boiling water
  • ½ cup organic canola oil

  • 1 organic large egg yolk
  • 255 g. organic flour

  • 1 organic vanilla extract

  • Decorating Tips #2, 8, 32, 21, 133, 26, 48


Preheat oven to 350 degrees.

Line a 9 x 13 baking pan with parchment paper.

In a mixing bowl, add the flour, baking powder and sea salt and whisk together. Set aside.

In the bowl of your stand mixer fitted with paddle attachment, add the sugar, cocoa, chocolate chips, vanilla bean and water. Mix on low until combined and all the chocolate has melted.

Add the egg, egg yolk, canola oil and the flour mixture.

Mix on low until all ingredients are combined. Do not over mix.

Pour batter into baking pan and spread evenly.

Bake for 12-14 minutes or until a wooden pick inserted in center comes out clean.

Once the brownies have cooled, remove from baking pan. Cut them into squares, rectangles or triangles. It’s fun to make them all different.

Next, start the frosting. In the bowl of your stand mixer fitted with paddle attachment, add the butter, powdered sugar, vanilla extract and water. Mix on low until all ingredients are combined then speed mixer up to high for 1 minute or until light and fluffy.

Separate the frosting into eight small dishes. Add the below colors to create different colors, and leave one dish uncolored for the eyes.

Blue – ½ tsp. ColorKitchen Blue Dye

Green – ½ tsp. ColorKitchen Green Dye

Orange – ½ tsp. ColorKitchen Orange Dye

Pink – ½ tsp. ColorKitche Pink Dye

Purple – ¼ tsp. ColorKitchen Blue Dye + ¼ tsp. ColorKitchen Pink Dye

Yellow – 1 tsp. ColorKItchen Yellow Dye

Chocolate – 5 g. organic Dutch cocoa

Add each of the frostings into piping bags. Use tip #2 for the chocolate, tip #8 for the white, tip #32 for purple, tip #21 for pink, tip #133 for blue, tip #26 for orange, tip #48 for yellow and for green I just spread with a knife.

Once all the frosting is in piping bags, just pipe different designs on each brownie to create different kinds of monsters! This part is so fun because you can do anything!

Once all the monsters are colored, add eyes by piping white circles onto each one. Then add a small chocolate dot in the center.

Create mouths with the chocolate or with gummy worms, and add hair with any of the colors!

Store in an airtight container.

Baker’s Note: To make these brownies gluten free, just substitute the organic flour for an organic gluten free flour blend, my favorite is Namaste Organic Perfect Flour Blend.
