Making Father’s Day special with cookies

This photo below is of my dad and me. I love my dad with all my heart and soul. He would do anything for his little girl! I called him this morning to wish him a Happy Father’s Day and he was hammering away in the house (my parents have been doing a renovation project).

When I saw Dad last Sunday I gave him these Banana Walnut Chocolate Chunk Cookies because I knew this week we probably wouldn’t be able to go anywhere as Grumpy was on call for work. I wish my dad the best day ever – although I know he is doing what he would do any other day of the week – keeping busy! My dad doesn’t sit around idle doing anything!

Banana Walnut Chocolate Chunk Cookies – A Special Father’s Day treat

One of dad’s least favorite foods is peanut butter and this has always been a teasing point for all of us kids – and it also became one for my kids! My little boys would do what they could to “trick” poppa into eating something that had peanut butter in it and then get him to say he liked it!

However, my Dad LOVES anything with bananas, nuts, and chocolate, so I knew these Banana Walnut Chocolate Chunk Cookies would be a hit with him.

My other “daddy” is my father-in-law (Grumpy #1). He also has my heart. For Grumpy #1 loves me too even though he wouldn’t admit it (not too often anyway!). There is something about these Grumpy men that I just seem to have a soft spot for! I made sure he received some of these Banana Walnut Chocolate Chunk Cookies too!

I recently bought Martha Stewart’s Cookies Cookbook and went through it to mark all the cookie recipes I want to try. These Banana Walnut Chocolate Chunk Cookies were first on my list because I had one single overripe banana on my countertop.

Grumpy didn’t eat his banana in his lunch on Friday so I had it sitting on my counter getting really ripe since it sat in his lunch box all day Friday and Saturday (I wasn’t home to empty his lunch box until Saturday night!)

I didn’t follow her recipe exactly, but the cookies turned out very tasty with my adjustments. These cookies turn out to be a soft cookie. (meaning Grumpy will like them).

What you need to make Banana Walnut Chocolate Chunk Cookies

Bananas: Overripe bananas are best. They are softer, easier to mash, and sweeter than one that is just ripe enough to eat.

Flour: I like to use white whole wheat flour for baking cookies. This brand is my favorite brand.

Sugar: Granulated sugar is the type of sugar I used in this recipe. I’m good with any brand of cane sugar that I can buy on sale and don’t really think it makes a difference in baking.

Chocolate Chunks: Any type of chocolate you want to use. We love bittersweet chocolate chunks.

Walnuts: I like to buy my walnuts in halves and chop them myself with this handy nut chopper.

Insulated Cookie Tray: this is my very FAVORITE Insulated Cookie Tray. It’s large and will bake a lot of cookies at once.

Silpat Baking Mat: It is the best invention ever. It keeps your cookies from sticking and is very easy to clean.
