Ingredient Notes and Substitutions

Here are some notes on ingredients. For a full list of ingredients, check out the recipe card below.

  • Butter- I use unsalted butter and leave at room temperature for 2 hours before baking.
  • Sugar- I like to use a combination of granulated sugar and light brown sugar. It creates a moist and chewy texture and a hint of caramel flavor from the molasses.
  • Eggs- Pull the eggs out at room temperature 1-2 hours before baking.
  • Mini chocolate eggs- I use an assortment of colorful M&M Mini Eggs. They have a nice crackly shell which makes these bars extra delicious. You can use any type of Easter chocolate candy, such as peanut M&M’s, Cadbury Mini Eggs, butterscotch chips, or peanut butter chips. Just make sure it’s colorful and tasty!
  • Kosher salt- Salt helps balance out the sweetness and enhances the flavor.
  • White chocolate chips- I use Ghirardelli Premium White Chocolate Chips. They hold their shape when baking and do not taste artificial.

Expert Baking Tips

Make sure to line baking pan with parchment paper. This will make it so simple to remove cookie bars from the pan and then easily cut into squares.

Spread your cookie dough evenly. This will ensure even baking and avoid areas that are over baked and areas that are under baked.

Do not over bake. These cookie bars have crisp edges but are slightly under done in the middle.

Halfway during baking, sprinkle the remaining chocolate chips and mini chocolate eggs on top. This will help make a beautiful and colorful presentation.

To get the perfect slice, dip a sharp knife inside a tall glass or container of hot water for 20-30 seconds. Wipe blade with paper towel to remove excess water. Slice into even squares.

Frequently Asked Questions

How do I know when my cookie bars are done?

Test with a wooden toothpick. If it comes out with just a few cookie crumbs, the bars are done. Each oven is different but I suggest checking at 25 minutes and add additional time if needed.

How long should I let cookie bars cool?

I suggest letting the bars cool for a minimum of 30 minutes. Removing them too soon can cause them to break. You can also place them in the refrigerator or freezer to speed up the process.

How do I keep the bars soft and chewy?

Avoid overbaking, as this can make them dry and crumbly. Remove them from the oven when the edges are golden, but the center still looks slightly underbaked. They will continue to set as they cool.

Can I add other mix-ins?

Yes, you can. Chopped nuts, sprinkles or even shredded coconut can add extra flavor and texture. Just be mindful not to add too many mix-ins, as it could change the consistency of the bars.

How do I get clean cut for each bar?

Score the bars with your knife before you make a complete cut. This will help you visually see your squares and avoid any mistakes.

Storing and Freezing

You can store these Easter Mini Egg Cookie Bars inside an airtight container for up to 1 week.

Freezing

Wrap your cookie squares well with plastic wrap. If planning to stack them, make sure to place a piece of parchment in between each bar to prevent them from sticking. Freeze cookie bars for up to 3 months.

Thaw bars overnight inside refrigerator and bring to room temperature before serving.
