Grasshopper Brownie Bars

Grashopper brownie bars 3Whether you are looking for a festive St. Patty’s Day treat, or just in the mood for the delightful combination of chocolate and mint, this allergy friendly grasshopper brownie bar recipe is sure to please.

I love anything made with chocolate and mint but, why do we call it a “grasshopper”? After a quick Google search, I learned that a popular 50’s after dinner drink made with crème de menthe and crème de cacao is the origin. It got its name due to the green tint in the crème de menthe. Mystery solved!

So, with that little tidbit of history, hop into your kitchen and whip up a batch of these tasty treats. You might even want to put on a little Elvis Pressley or Chuck Berry to set the mood.

Happy Baking!

Melt 1 cup of chocolate chips in microwave on 50% power setting in 30 second intervals, stirring frequently. Once chocolate is melted and smooth, stir in 2 Tb shortening until incorporated. Pour over mint filling and spread with offset spatula until mint filling is completely covered. Chill in refrigerator for another 30 min.



To remove from pan, use foil overhang as handles and simply lift up and out of pan. Place on a cutting board and cut into squares.

Double Chocolate Mint Brownies

Hey there chocolate mint lovers!

Here is a fun and simple twist on our already delicious fudgy brownies. These double chocolate mint brownies remind me of Girl Scout Thin Mint cookies, only chewy… YUMMY!

The trick to making them really minty is in the peppermint oil. It turns out that not all peppermint oil extracts are created equally. My friend and pastry chef, Kim Boos at Tee&Cakes clued me in on this. Kim recommended Lorann Oils Natural Peppermint Oil available locally in Boulder at Peppercorn or online. But take caution… This stuff is CONCENTRATED! It even says on the bottle “keep out of reach of children”. A few drops goes a long way toward mint chocolate perfection.

Prepare brownies as directed on the back of the box, mix in 1/8 tsp of peppermint oil with the vanilla. Add chocolate chips with the contents of cocoa bag. Bake as directed. And remember, brownies are always best when slightly under-done. I always take them out early, then let cool completely to get them to set up (even though it’s hard to resist diving right in when they are warm and gooey).

Happy Baking!
