What You’ll Need

1/2 cup unsalted butter
1 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
1/2 cup all-purpose flour
1/3 cup cocoa powder
1/4 teaspoon salt
1/4 teaspoon baking powder
1/2 cup mini chocolate chips
1/2 cup frosting (for topping)
Chocolate sprinkles (for garnish)

Ingredient Notes:

Butter: Unsalted butter works best to control the salt levels; feel free to substitute with coconut oil for a dairy-free option.
Sugar: Granulated sugar creates a crispy top while brown sugar can add moisture and richness.
Eggs: Vital for binding; use flax eggs for a vegan swap.
Chocolate Chips: You can experiment with dark chocolate or white chocolate chips for a fun twist.

How to Make This Recipe

1. Preheat Your Oven

Preheat your oven to 350°F (175°C) and grease a baking pan. The warm-up ensures even baking for that perfect chewy texture.

2. Prepare the Butter Mixture

In a mixing bowl, melt the butter and stir in the sugar until combined. The rich aroma of melted butter mingling with sugar creates an enticing base.

3. Add the Eggs & Vanilla

Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract. The batter should be glossy and smooth, with a comforting sweetness starting to emerge.

4. Combine Dry Ingredients

In a separate bowl, combine the flour, cocoa powder, salt, and baking powder. Whisk gently to aerate; the delightful scent of cocoa will fill the air.

5. Mix Wet and Dry Ingredients

Gradually mix the dry ingredients into the wet mixture until well combined. The batter should be thick but still pourable, showcasing a sumptuous chocolate color.

6. Fold in Chocolate Chips

Fold in the mini chocolate chips, adding pockets of melty goodness throughout the batter. This step enhances the texture and flavor dramatically.

7. Pour and Spread

Pour the batter into the prepared baking pan and spread evenly. The thick batter should sit snugly in the corners, promising a perfectly baked brownie.

8. Bake to Perfection

Bake for 20-25 minutes until set. The top should look firm with slight cracks, releasing an incredible chocolate aroma that fills your kitchen.

9. Frost and Garnish

Once cooled, spread frosting on top and sprinkle with chocolate sprinkles. The glossy finish and colorful sprinkles add a festive touch.

10. Cut and Serve

Cut into squares and serve warm or at room temperature. Enjoy the rich, fudgy texture paired with the sweet frosting—an irresistible treat!

Essential Tools

Mixing bowls: For combining ingredients.
Electric mixer (optional): To make blending easier.
Spatula: For scraping down the sides.

Meal Prep & Storage Tips

Store leftover brownies in an airtight container at room temperature for up to 3 days. For longer storage, consider freezing them for up to 3 months. Thaw at room temperature before indulging.
