Cookie Bars with Oreos and Gems

If you love Oreos and Gems or M&M’s these bars are for you..!

Hmm..So in short, these bars are for everyone.. because let’s face it who doesn’t like Oreos and Gems?! I made these bars after I came across a recipe on one of my favourite blogs Averie Cooks. Averie made the most gorgeous looking cookie bars with Oreos and M&M’s, and my heart just melted when I saw the pictures! I’ve adapted the recipe completely to fit my taste and to make these bars eggless. They’re chewy, loaded with Oreos and topped with lots and lots and lots of Gems! If you have kids, you must make these..I’m sure they’ll love them!

If you’re wondering what cookie bars are and what they taste like, let me give you some insight. Cookie bars are made by baking cookie dough in a square brownie tin or a rectangular tin until a skewer inserted comes out clean with a few crumbs. You make cookie dough the regular way, only when it comes to baking you will treat them like cake batter. They’re extremely easy so if you’re scared of making cakes you must start with these. Cookie dough has a tendency to turn out great no matter what so you have no reason to worry. These bars will rise! 🙂

In Averie’s recipe she used an egg but a lot of my readers request for eggless recipes so this one’s for them! ❤ If you prefer the texture of eggs in your cookies you can just add 1 egg and skip the milk altogether. Eggs are normally added to give moisture but these bars are moist enough so don’t worry if you’re going the eggless route. You’re safe!

You can add M&M’s to these cookies..I used the Indian equivalent of M&M’s i.e. Gems. They’re slightly sweeter but more or less the same so use whatever chocolate coated candy is available in your country! It doesn’t matter..what matters is taste, which is impeccable! 🙂

RECIPE: Cookie Bars with Oreos and Gems

Makes: 9 bars     Prep Time: 10 minutes      Baking Time: 20 minutes


  • Softened Butter, 100 grams or 1/2 cup
  • Sugar, 100 grams (half powdered white sugar and half dark brown sugar) or 1/2 cup
  • Vanilla Essence, 1 teaspoon
  • Flour, 130 grams or 1 cup
  • Baking Powder, 1 teaspoon
  • Salt, 1/2 teaspoon
  • Milk, 4 tablespoons
  • Oreos, 8-10
  • Gems, 1/2 cup


Preheat oven for 10 minutes at 180 degrees Celsius. Line a square tin with parchment paper or foil and grease it with butter or oil. Set aside to be used later.

In a bowl, whisk butter until light in color and fluffy. The color of the butter will change slightly so don’t look for a dramatic change. Whisking for 2 minutes is enough.

Add in the sugars and whisk again for 2-3 minutes. Add vanilla essence and mix it in.

Add in the flour, baking powder and salt to the wet ingredients slowly and keep folding them in. Keep adding milk to make the dough easy to work with. Do not overmix. Once you no longer see dry flour bits stop mixing.

Toss in the Oreos and gems (leave some for the top) and fold them in. Transfer this dough to the lined tin and top with chopped up Oreos and leftover gems. Make it pretty!

Bake for 15 minutes at 180 degrees Celsius, then take out the tin and  cover it with foil to avoid browning on top. Bake again for 5 more minutes. Allow to cool completely for at least 2 hours before you take them out. They’re really fragile at this point so be careful!

Once cool, cut cookie bars in squares and enjoy!
