Gear Checklist

Before you start baking, ensure you have the following gear on hand:

• Mixing bowls – For combining ingredients.
• Measuring cups and spoons – Accurate measurements are key.
• Whisk or electric mixer – To make mixing quick and easy.
• 9×13 inch baking pan – The perfect size for these brownies.
• Parchment paper – For easy removal and cleanup.
• Cooling rack – To cool your brownies evenly.

How to Prepare Homemade Cosmic Brownies

Now that you have everything you need, let’s get into the step-by-step process of making these delightful brownies.

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). This step is crucial to ensure even baking.

Step 2: Prepare the Baking Pan

Line your 9×13 inch baking pan with parchment paper, leaving some overhang on the sides for easy removal later. This will make cutting and serving your brownies much easier.

Step 3: Mix the Wet Ingredients

In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until well combined. Add the eggs and egg yolk one at a time, mixing well after each addition. Stir in the vanilla extract and vegetable oil until everything is smooth.

Step 4: Combine the Dry Ingredients

In another bowl, whisk together the flour, cornstarch, cocoa powder, salt, and baking soda. This ensures that all the dry ingredients are evenly distributed.

Step 5: Combine Wet and Dry Ingredients

Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can make the brownies tough.

Step 6: Add Chocolate Chips

Fold in the semi-sweet chocolate chips gently until they are evenly distributed throughout the batter.

Step 7: Pour and Bake

Pour the brownie batter into the prepared baking pan and spread it evenly. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

Step 8: Prepare the Frosting

While the brownies are baking, prepare the frosting. In a small saucepan over low heat, melt the 6 tbsp of butter. Once melted, stir in the milk and cocoa powder until smooth.

Step 9: Frost the Brownies

Once the brownies are done baking, remove them from the oven and let them cool in the pan for about 10 minutes. Then, pour the frosting over the warm brownies and spread it evenly. Sprinkle the rainbow chips on top while the frosting is still warm, so they stick.

Step 10: Cool and Slice

Allow the brownies to cool completely in the pan on a wire rack. Once cooled, lift them out using the parchment paper and slice them into squares. Enjoy your Homemade Cosmic Brownies!

Substitutions by Diet

If you have dietary restrictions or preferences, here are some substitutions you can make:

• Vegan: Use plant-based butter and replace eggs with flax eggs (1 tbsp ground flaxseed + 2.5 tbsp water per egg).
• Gluten-Free: Substitute all-purpose flour with a gluten-free flour blend.
• Dairy-Free: Use almond or coconut milk instead of regular milk and dairy-free chocolate chips.
• Reduced Sugar: You can use a sugar substitute that measures 1:1 for granulated sugar and brown sugar.

Getting the perfect brownie can take a bit of trial and error, but here’s a rough timeline to help you perfect your Homemade Cosmic Brownies:

• First Attempt: Test the basic recipe as outlined.
• Second Attempt: Adjust baking time if necessary; some ovens vary.
• Third Attempt: Experiment with different types of chocolate chips or add-ins.
