Key ingredients
These are the key ingredients and everything you need to know about why we use them or any substitutions. You can find the full list of ingredients in the recipe card below.
- Chocolate - I like to use dark chocolate for my brownies, but if it is too much for you, semi-sweet or a mix of both would work very well.
- Cocoa powder - I typically use Dutch-processed cocoa powder, but natural unsweetened cocoa powder is a suitable substitution.
- Cornstarch - This plays a critical role in giving us thicker brownies that remain nice and fudgy. It also helps give us that delicious crinkle top.
- Butter & Oil - Unlike most brownies, I like to use a mix of both butter and oil, but you can use just butter in these brownies too with amazing results.
- Sugar - For brownies that are on the chewier side, I like to use a mix of granulated and brown sugar. You can choose to use just one or the other.
- M&Ms - You can use any of your favorite m&m candies. mini m&m or regular m&m candies are traditional, but you can also use any of the m&m flavors to match your mood
How to make
The best part about making these M&M brownies is just how quick and easy it is
- Line your 8x8 inch baking pan with parchment paper and preheat your oven to 350F. Add your butter, chocolate, and sugar together into a large saucepan. Heat until the butter and chocolate are half melted. Remove from heat and stir until the butter and chocolate are fully melted and mixed well together.
- Add in the oil, egg and vanilla extract into your melted butter mixture. Beat vigorously with a wire whisk for at least 3 minutes.
- Mix in the all-purpose flour, cocoa powder, cornstarch, and salt into your wet ingredients and stir until your dry ingredients are just combined. Fold in the M&Ms.
- Pour the batter into your prepared pan and add more M&Ms to the top of the brownie batter. Bake for roughly 35 - 40 minutes.
Expert baking tips
- The most important way to ensure you get the best brownies is to make sure you are correctly measuring your ingredients, particularly the flour. You should fluff up the flour and then spoon it into your measuring cup then sweep of the excess. If you want to make sure you get consistent results, you can convert the recipe to metric and use a kitchen scale.
- Make sure your ingredients are at room temperature. If you need to quickly bring eggs to room temperature, you can leave them in a bowl of warm water for five minutes before using.
- For brownies with that glossy top, you need to really beat the eggs and sugar together very well. It also helps to add the sugar to the hot butter before adding the eggs.
- Don't forget to line the baking pan with parchment paper for easy removal once your brownies have cooled down.
- Use a light-colored metal pan. Dark pans encourage fast browning which can leave you with burnt brownies and glass pans do not conduct heat as well leaving you with brownies that longer to bake and are a lot more dense.
- Don't mix in the M&Ms too much as the color from the candies will bleed out and make it harder to see how deliciously colorful they are when you slice them.
- Change out the colors of the M&Ms to match any special occasions or holidays!
Storage info
M&M brownies can be stored in many ways as long as they are in an airtight container. At room temperature, they should be good for up to five days. They will last for about a week in the refrigerator. If stored in the freezer, they should last for over a month. Thaw in the refrigerator overnight.
Place parchment paper between the layers of your brownies if you plan on freezing them.
