How to Make M&M’s Blondies
-
Preheat oven: Set your oven to 350°F (175°C) and prepare an 8×8 inch baking pan by lining it with parchment paper. This makes for easy removal after baking!
-
Cream butter and sugar: In a large mixing bowl, cream the softened butter and brown sugar together until the mixture is light and fluffy. This step is vital for a nicely textured blondie.
-
Add eggs and vanilla: Incorporate the large egg, egg yolk, and vanilla extract into your butter-sugar mixture. Mix until the blend turns truly light and airy, which adds to the deliciousness of the finished treat.
-
Mix in dry ingredients: Gently add the all-purpose flour and salt to the wet mixture. Stir just until everything is combined; over-mixing can lead to tougher blondies!
-
Fold in chocolate and M&M’s: Carefully fold in the chopped semi-sweet chocolate and the Valentine’s Day M&M’s. Enjoy the cheerful colors and think about the happiness they’ll bring!
-
Spread and top: Pour the blondie batter into your prepared pan, spreading it evenly. Top with a handful of extra M&M’s for that delightful crunch and flair.
-
Bake: Place the pan into your preheated oven and bake for 20-23 minutes. Look for a lovely golden-brown color around the edges—they’ll be soft in the middle.
-
Cool and slice: Once baked, allow the blondies to cool completely in the pan. This prevents them from crumbling when you slice them into squares, ready for indulgence!
Optional: Serve warm with a scoop of vanilla ice cream for an extra special treat!

Simply cover the bowl tightly and refrigerate to maintain freshness. For the best results, fold in the chocolate and M&M’s right before baking for optimal texture and flavor. When you’re ready to bake, pour the chilled batter into the pan, add the extra M&M’s on top, and bake as instructed.

Chef's Helpful Tips
- For making the perfect M&M’s Blondies, always use softened unsalted butter to better control the sweetness and achieve a fluffy texture when creaming with brown sugar.
- When adding flour, be sure to mix gently just until combined to avoid tough blondies, as over-mixing can affect the final product.
- For an added depth of flavor, consider enhancing the mixture with a bit of espresso powder or a pinch of cinnamon alongside the dry ingredients.
- Remember to keep an eye on baking time since ovens can vary; aim for golden brown edges and a slight softness in the center for that perfect chewy consistency.
M&M’s Blondies Recipe FAQs
What type of M&M’s should I use for the blondies?
Absolutely! For a festive touch, use Valentine’s Day M&M’s, which add a pop of color and a hint of fun. Regular or mini M&M’s work beautifully as well, depending on your preference.
How should I store my M&M’s Blondies?
I recommend keeping your M&M’s Blondies in an airtight container at room temperature for up to 5 days. This helps retain their soft, chewy texture and delicious flavor. If you want them to last longer, the fridge is also an option, though they may dry out slightly in there.
Can I freeze M&M’s Blondies for later?
Absolutely! To freeze, wrap each blondie tightly in plastic wrap and place them in a freezer-safe bag. They will keep well for up to 3 months. When you’re ready to enjoy them, simply thaw them in the fridge overnight or on the counter for a few hours.
What should I do if my blondies are too dry?
If your M&M’s Blondies turn out a bit dry, it’s often due to over-baking. So for future batches, I suggest checking them at the 20-minute mark. Keep an eye out for that golden-brown edge and a soft center. If you’ve already baked them, a scoop of ice cream on top can make them delightful again!
Are these blondies safe for people with nut allergies?
Yes, this M&M’s Blondies recipe is nut-free as written! However, always double-check the packaging of your M&M’s and chocolate to ensure they are made in a nut-free facility, especially if allergies are a concern.
Can I use different flavors of M&M’s in this recipe?
Very much! Feel free to experiment with different M&M’s flavors—peanut, pretzel, or even seasonal varieties like pumpkin spice. Each type will bring a delightful twist to your M&M’s Blondies!
