📖 Recipe Variations
The first time you try any new recipe we recommend that you make it just as it is written on the recipe card since that is how the recipe has been tested. However, the next time you make our recipe, you might want to try one of these ideas:
- sprinkle mini chocolate chips, white chocolate chips, or even peanut butter chips into the batter before baking
- to make these into Halloween candy cookie bars, top with your favorite candies like reese’s pieces, m&m candies, or chop up your favorite candy bars like kit kats, snickers etc.
- look for candy eyes in your local grocery store’s cake aisle for a fun ‘spooky’ addition
🎉 Holiday Variations
These bars can easily be dressed up for any holiday or special occasion.
Simply change the color of the frosting and use sprinkles that match your party theme. Chocolate cookie bars are great for birthdays, graduation parties, and more. Try pastel frosting and sprinkles for Easter or a baby shower. Think pink frosting with red and white sprinkles for Valentine’s day. You could even do red, white, and blue for the 4th of July.
