Key Ingredients & Substitutions
Unsalted Butter: Using unsalted butter gives you control over the saltiness of the brownies. If you only have salted butter, just reduce the added salt to a pinch.
Granulated Sugar: This sugar helps create the brownie’s texture. For a different flavor, you can use brown sugar instead, which adds a slight caramel note.
Eggs: Eggs provide moisture and structure. If you’re looking for an egg alternative, consider using unsweetened applesauce or a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water, let it sit to thicken).
All-Purpose Flour: This gives structure to the brownies. If gluten-free, use a 1:1 gluten-free baking flour that contains xanthan gum.
M&M Candies: They add color and crunch! You can swap them for other chocolates, nuts, or even dried fruits for a different twist.
How Do I Achieve the Perfect Fudgy Texture?
The secret to fudgy brownies is in the mixing and baking time! Follow these steps to get that perfect dense, chewy texture:
- Mix the butter and sugar fully, ensuring they’re combined well before adding the eggs.
- Be cautious not to overmix when adding the dry ingredients. Stir just until combined to keep them gooey.
- Bake at 350°F (175°C) and check for doneness at 25 minutes. Underbaking slightly ensures that fudgy texture, so look for a few moist crumbs on the toothpick, not wet batter.

How to Make Fudgy M&M Brownies
Ingredients You’ll Need:
Main Ingredients:
- 1 cup (2 sticks) unsalted butter
- 2 cups granulated sugar
- 4 large eggs
- 1 tablespoon vanilla extract
- 1 cup all-purpose flour
- 3/4 cup unsweetened cocoa powder
- 1/2 teaspoon salt
- 1/2 teaspoon baking powder
- 1 cup M&M candies (plus extra for topping)

How Much Time Will You Need?
This delicious recipe will take about 15 minutes to prepare and then 25-30 minutes to bake. After baking, allow the brownies to cool before cutting. You’ll be enjoying these scrumptious treats in no time!
Step-by-Step Instructions:
1. Prepare the Oven and Pan:
Start by preheating your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper or grease it well with a bit of butter or cooking spray to prevent sticking.
2. Melt the Butter:
In a medium saucepan over low heat, melt the unsalted butter completely. Once melted, take it off the heat and let it cool slightly.
3. Mix in Sugar and Eggs:
Stir the granulated sugar into the melted butter until it’s well combined. Next, add the eggs one at a time, mixing well after each addition to create a smooth batter. Add in the vanilla extract and give it another good mix.
4. Combine Dry Ingredients:
In a separate bowl, whisk together the all-purpose flour, cocoa powder, salt, and baking powder. This helps distribute the dry ingredients evenly!
5. Mix Together Wet and Dry Ingredients:
Gradually add the dry mixture to the wet mixture. Stir just until everything is combined; don’t overmix, as this can make your brownies tough.
6. Add the Goodies:
Gently fold in the M&M candies (and chocolate chips if you want extra gooeyness). This will give your brownies that colorful crunch!
7. Pour and Spread:
Pour the brownie batter into the prepared baking pan and spread it out evenly to ensure every corner gets that fudgy goodness.
8. Top with M&Ms:
Sprinkle a few extra M&M candies on top for added color and charm!
9. Bake the Brownies:
Pop the pan into the preheated oven and bake for about 25-30 minutes. Keep an eye on them! You want a toothpick to come out with a few moist crumbs, not wet batter for that fudge texture.
10. Cool and Cut:
Once done, remove them from the oven and let them cool completely in the pan on a wire rack. Once cooled, slice into squares and serve!
11. Enjoy!
Your fudgy, colorful M&M brownies are ready to be enjoyed! Perfect for sharing, or keep them all to yourself—you deserve it!

Can I Use Different Types of Chocolate?
Absolutely! You can substitute the unsweetened cocoa powder with dark cocoa powder for a richer flavor. Additionally, feel free to use milk chocolate or dark chocolate chips instead of M&M candies for a different twist!
How Should I Store Leftover Brownies?
Store any leftover brownies in an airtight container at room temperature for up to 3 days. For longer storage, you can refrigerate them for up to a week or freeze them for up to 3 months. Just thaw them at room temperature when you’re ready to enjoy!
Can I Make These Brownies Without Eggs?
Yes! You can replace the eggs with 1/4 cup of unsweetened applesauce per egg, or use a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water). Let the mixture sit for a few minutes until it thickens before adding it to the batter.
What Should I Do If My Brownies Are Too Dry?
If your brownies turn out dry, it might be due to overbaking. Next time, start checking for doneness a few minutes early. If they’re already baked, try to serve them with ice cream or whipped cream to add moisture and richness!
