Description

Fudgy brownies dotted with vibrant M&M’s candies create a festive, chocolatey treat perfect for celebrations.


Ingredients

Scale
  • 1 1/4 cups (285 g) unsalted butter
  • 2 ounces semi-sweet chocolate, chopped
  • 1 1/2 cups (300 g) light brown sugar, packed
  • 3/4 cup (150 g) granulated sugar
  • 4 large eggs, room temperature
  • 1 cup (100 g) Dutch process cocoa powder
  • 1/2 teaspoon salt
  • 3 teaspoons vanilla extract
  • 3/4 cups (95 g) all-purpose flour, spooned and leveled
  • 2/3 cup M&M chocolate candies

Instructions

  1. Preheat oven to 350°F. Spray the bottom of a 8 x 8 baking pan with non-stick baking spray and line with parchment paper. Allow the sides of the parchment to hang over the sides of the pan by an inch or two for easy removal of the brownies once baked.
  2. Melt the butter, chocolate and sugars in a heat safe bowl over a double boiler. To create a double boiler, fill a medium sauce pan with 2 inches of water and place over medium low heat. Place the heat safe bowl over the pan, being careful not to let the bowl touch the water below. Stirring frequently, heat the ingredients until melted. The mixture will be grainy but glossy. Remove the bowl from the heat and set aside to cool slightly.
  3. Add the eggs, one a time, whisking well between each addition. Continue to whisk until the mixture lightens in color and is smooth and shiny.
  4. Add the cocoa powder, salt and vanilla. Stir to combine well.
  5. Add in the flour, folding into the mixture with a large spatula until just a few streaks of flour remain. Do not over mix.
  6. Transfer the batter to the prepared pan and level the top with an offset spatula.
  7. Sprinkle the M&M’s over the top of the brownies.
  8. Bake for 45 to 50 minutes, or until the edges are set and a toothpick inserted two inches from the side of the pan comes out with just a few crumbs remaining. Do not over bake or the brownies will be cake-like and dry instead of fudgy.
  9. Remove the pan from the oven and set on a wire rack to cool. Cool completely before slicing into squares.

Notes

  • Let brownies cool completely before cutting.
  • For cleaner cuts, use a plastic knife.
  • Store in airtight container at room temperature for up to 5 days.

Ingredients and Substitutions

Base Components

Butter builds the foundation for fudgy texture. However, you can substitute coconut oil for dairy-free needs. Use refined coconut oil to avoid coconut taste. Make sure all substitutions measure equal amounts by weight.

Dutch process cocoa delivers deep, mellow chocolate flavor. Natural cocoa works too, but expect slightly sharper taste. Either way, spoon cocoa into measuring cups before leveling to prevent packing.

Sweetness Adjustments

Brown sugar contributes moisture while granulated sugar creates crust. For less refined options, coconut sugar replaces brown sugar beautifully. Alternatively, reduce total sugars by 1/4 cup if preferred.

M&M’s provide decorative crunch. Alternatively, try chopped nuts or freeze-dried berries for different textures. Just press add-ins gently to prevent sinking during baking.

How to Make Happy M&M’s Brownies

Step 1: Prep Work Saves Time

Line your pan with parchment paper flaps. Doing this allows easy lifting after cooling. Greasing the paper prevents sticking. Meanwhile, preheating the oven ensures consistent temperatures. Use these minutes to chop chocolate uniformly.

Step 2: Double Boiler Mastery

Melting ingredients work best with gentle heat. Place butter, chocolate, and sugars in a heat-safe bowl. Set it over simmering water, ensuring no contact between bowl and water. Stir until everything melts smoothly. Let mixture cool slightly while preparing eggs.

Step 3: Egg Incorporation Secrets

Adding eggs one by one prevents scrambling. Whisk thoroughly after each egg. Soon, the batter becomes pale and glossy. Watch the change happen as you work!

Step 4: Dry Ingredient Integration

Sift cocoa powder to eliminate lumps. Combine cocoa, salt, vanilla, and flour beforehand. This step ensures even distribution. Finally, fold until streaks nearly disappear. Overmixing causes tough brownies.

Step 5: Baking Precision

Distribute batter evenly in your pan. Top generously with candies. Bake until edges pull away slightly. A toothpick test near the edge should yield moist crumbs. Cool completely before slicing unless you enjoy messy fingers!

Pro Tips for Success

For glossy tops, dissolve sugars completely during melting. Moreover, proper cooling sets structure. Though tempting, cutting warm brownies squishes layers. Along with patience, use a plastic knife for cleaner cuts through candies.

Flavor Variations

Mint lovers can swap vanilla for peppermint extract. Alternatively, fold crushed Oreos into batter with green M&M’s for seasonal fun. For double chocolate, incorporate mini chocolate chips. Peanut butter fans might swirl nut butter atop batter before adding M&M’s.

Serving Suggestions

Warm squares pair wonderfully with vanilla ice cream. Additionally, drizzle caramel sauce for sophistication. Consider stacking brownie bites between dollops of whipped cream. For contrast, serve alongside savory treats like a broccoli cheese soup copycat during gatherings.

Storage and Freezing Instructions

Store cooled brownies airtight at room temperature for five days. For longer freshness, refrigerate up to two weeks. Freeze layers separated by wax paper three months maximum. Let thaw covered on counters overnight.

When freezing baked goods, consider preparing comforting meals like instant pot rice soup as freezer staples too. Balancing sweet indulgences with wholesome dishes maintains happy kitchens.

FAQs About Happy M&M’s Brownies

Why did my M&M’s crack during baking?

High oven heat stresses candy shells. To prevent cracking, reduce temperature slightly. Additionally, place candies during last five minutes of baking instead.

Can I use different candy types?

Yes! Chocolate candies with similar sizes work well. Avoid overly soft varieties that melt into batter. Press any substitutes gently onto tops for visibility.

Do I need Dutch process cocoa?

Dutch process enhances flavor but standard cocoa works. However, natural cocoa reacts differently with leaveners. Since this recipe uses no baking powder, substitutions succeed easily.

How to prevent dry brownies?

Careful timing prevents overbaking. Check several minutes early using the toothpick test. Remember residual heat continues cooking during cooling periods.

Why are my edges tough?

Dark pans absorb more heat. Consider reducing oven temperature by 25°F when using dark metal pans. Alternatively, insulate edges with foil strips halfway through baking.

Can I double this recipe?

Doubling works perfectly! Use a 9×13 pan instead. Baking time increases roughly ten minutes but monitor closely after 45 minutes.

Final Thoughts

Ultimately, Happy M&M’s Brownies bring delightful simplicity to dessert tables. Their fudgy texture contrasts beautifully with playful candy crunch. Better still, they satisfy chocolate cravings without complicated techniques.

Next time hunger strikes, bake these beauties. Whether celebrating Valentine’s Day or just Wednesday, every bite spreads joy!
