Blondie vs Brownie

We have all heard of brownies. They are a very popular treat and dessert. But have you ever had a Blondie?

A blondie is like a brownie but without the chocolate. Sometimes there are chocolate chips added. But blondies are essentially a brownie without the cocoa powder or chocolate added to the batter.

There is also more vanilla in Blondies than in a brownie batter.

M&Ms In Place Of Some of The Chocolate Chips

The addition of M&Ms in these blondies change up the flavour. You can use regular M&Ms or minis. The choice is yours.

Around Christmas, there are special edition M&Ms which are the ones I like to use. Our favourite is the Mint M&Ms that are available around Christmas time only. I have also use the White Chocolate Peppermint M&Ms as well as a combination of the two. These flavours of M&Ms come in red, green and white which add that festive look to the blondies.

Great For Special Occasions

I love to make these and add them to Christmas baskets to give to all my friends. By using Christmas M&Ms, it adds Christmas colours to the blondies, making them more festive.

M&Ms also come in special occasion colours at different times of year. Pink for Valentines Day. Pastel colours at Easter. With all the colours available, these M&M Blondies can be made for any occasion.

Share These M&M Blondies With Friends and Family

This recipe makes a larger batch than a usual blondie recipe. I created this recipe for sharing. It has also been a hit with bake sales for our sons’ football games as well bake sales at school.

We also have a large family (10 children is considered a large family these days). So these don’t last long in our house.

This recipe will make 35 servings. (See how to store below).

Pan For Baking The Blondies

This recipe is baked in a cookie sheet. The best size is a 15″ x 10″ pan with raised edges like a jelly roll pan.

If you don’t have a pan that size, a 13″ x 9″ cake pan will also work. This will make a thicker blondie and the baking time will be longer. If using a cake pan, the baking time should be extended to 30-35 minutes.
