Unveiling the Enchanting Ingredients Behind the Best Halloween Brownies!

Just a handful of baking staples are all you need to make this Halloween brownies recipe come to life! 

  • Granulated Sugar – Regular granulated sugar helps sweeten the batter, eliminating any bitterness from the cocoa. 
  • All-Purpose Flour – We have not tested this recipe with any alternative flour. However, if needed a 1:1 gluten-free all-purpose flour should work. 
  • Cocoa Powder – This is crucial to creating the rich, fudgy flavor we look for in brownies! 
  • Cornstarch – This acts as a thickening agent and prevents gluten formation. As a result, it creates dense, moist, fudgy brownies that are absolutely to die for! 
  • Dark Chocolate Chips – Feel free to substitute semi-sweet or white chocolate chips, if preferred. Dairy-free options also work! 
  • Sea Salt – Just a sprinkle helps enhance the flavor of the cocoa and the sweet flavor of the batter. 
  • Large Eggs – These are crucial to create the fudgy consistency and help the brownies hold their shape! 
  • Butter – This contributes to the taste and texture of the brownies. Unsalted is best! If needed, you can substitute a dairy-free butter.
  • Vegetable Oil – When combined with butter, this practically guarantees that your brownies always turn out unbelievably moist and tender. 
  • Vanilla Extract – Use a high-quality, pure vanilla extract. 
  • Toppings – We use M&Ms, sprinkles, and candy eyeballs for festive, spooky faces. Feel free to get creative with any edible toppings and candies you have on hand!

Creepy, Crawly, and Delicious: The Ultimate Guide to Making Halloween Brownies

These brownies might look and taste gourmet, but they’re just as easy to make as your favorite store-bought boxed blend. 

  1. Prepare. Before you begin, preheat your oven, line a baking pan with foil or parchment paper, and grease it with nonstick cooking spray. Make sure you get the corners! 
  2. Melt. In a large microwave-safe bowl, add the butter and sugar, and microwave just until the butter melts. Add the oil, and stir to combine. 
  3. Whisk the wet ingredients. In the same bowl, add the eggs and vanilla, and whisk until smooth. 
  4. Mix the dry ingredients. Sift the flour, cocoa powder, cornstarch, and sea salt into the bowl of wet ingredients. Gently stir just until no streaks remain. Be careful not to overmix!
  5. Add the chocolate. Gently fold in the chocolate chips. 
  6. Decorate. Spread the brownie batter in an even layer in the prepared pan, and sprinkle your toppings of choice on top.  
  7. Bake. Place the pan in the preheated oven, and bake just until the brownies are set and a cake tester or toothpick can be inserted into the center and comes out clean or with just a few moist crumbs attached. Be super careful not to overbake! 
  8. Cool. Remove the brownies from the oven, and allow them to cool completely in the pan. This step is important! Otherwise, they’ll crumble and fall apart.
