It’s an extraordinary chocolate cookie recipe—we hope you enjoy it. We have a sneaking feeling you’ll have a hard time going back to plain ol’ chocolate chip after you make these.

Ingredients

1 cup granulated sugar
1 cup brown sugar
1 cup margarine
1 cup vegetable oil
1 egg
3 1/2 cup all-purpose flour
1 teaspoon vanilla extract
1/2 teaspoon salt
1 teaspoon baking soda
1 teaspoon cream of tartar
1 cup chocolate chips
1 cup rice krispies
1 cup oatmeal

When you try a recipe, and it doesn’t work out as well as expected – there usually are 3 reasons why: 1) you aren’t working with the same brands for the ingredients, 2) you aren’t using the same tools, or 3) you’ve knowingly or unknowingly made substitutions (i.g. margarine vs. butter).

Preferred Brands

For the ingredients in this particular recipe, you can use your favorite brands. Here are a few of our go-tos:

Flour – Wheat Montana All-Purpose Flour
Margarine – Blue Bonnet or Gold ‘n Soft
Vegetable oil – Crisco
Chocolate chips – Tollhouse Milk Chocolate Chips

Baking Supplies

Here are the baking supplies we use for this recipe to help make it as repeatable and predictable as possible:

Ceramic stoneware baking sheet by Pampered Chef – the ceramic material cooks evenly, and you won’t have the dark brown cookie bottoms you may have with dark nonstick pans.
Cookie scoop – makes each cookie the same size every time.

How to Make Chocolate Chip Cookies with Oatmeal and Rice Krispies

Follow these simple steps to make these delicious cookies.

Step 1 | Preheat oven to 375°F

Preheat your oven to 375 degrees.

Step 2 | Combine all ingredients except for mix-ins

In a large bowl, mix the brown sugar, granulated sugar, margarine, vegetable oil, egg, all-purpose flour, vanilla extract, salt, baking soda, and cream of tartar.

Step 3 | Mix well to make cookie dough

Mix well, just until the ingredients are blended. A stand mixer works really well for this dough.

Step 4 | Add mix-ins

Fold in the chocolate chips, rice krispies, and oatmeal.

You should have something really close to this mixture. Look at that beautiful cookie dough.

Step 5 | Drop by Spoonfuls onto baking sheet

Drop by spoonfuls onto a baking sheet. We received this stainless steel cookie scoop as a gift a few years ago. It works fantastic for measuring just the right amount.

We ordered this ceramic stoneware baking sheet from Pampered Chef. It took us the longest time to use it because we often get stuck in our own ways. However, it makes a big difference when baking cookies – allowing for even cooking. And a bonus – the bottom of the cookies don’t get dark like they tend to do with nonstick metal pans.

Step 6 | Bake for 8 to 10 minutes

Bake at 375 degrees for 8 to 10 minutes. You don’t want to overbake these cookies unless you like a crunchy cookie. Be sure to cool completely and store in an airtight container.

Frequently Asked Questions

Here are answers to commonly asked questions about making these cookies.

How to check if your cookies are done?

If your cookies are light golden brown on the top and the bottom, they are done. Do not overbake these cookies, especially if you don’t like a hard cookie. Try to stick to the 8 to 10 minute time recommendation, even if the cookies don’t look completely done. (Of course, this also depends on your oven.)

What to do with leftover chocolate chip cookies?

This is a large batch recipe making around 4 dozen. With any leftover chocolate chip cookies, you can freeze and save for holidays or unexpected guests, crumble over ice cream for a yummy dessert, freeze half the cookie dough before you bake the cookies…the delicious options are endless.

What variations can you make with this recipe?

This recipe is tasty as-is, but if you’d like to change it up a bit, add one cup mini Tollhouse chocolate chips or chocolate chunks instead of one cup of regular milk chocolate chips to add a different texture. For more of an oatmeal raisin cookie – add one cup raisins. For a fall version, add craisins, white chocolate chips, and walnuts.

How do you keep cookies from getting hard after baking?

Store your cookies in an airtight container to keep them from getting hard after baking them. We prefer plastic Tupperware to keep our baked goods from getting hard and dried out.

Can you undercook cookies?

Yes, you can undercook cookies, and it can cause your cookies to be too soft and fall apart. Another concern is food safety. Raw dough may contain bacteria, and you’ll want to make sure all food prepared with eggs and/or flour is cooked and handled correctly, according to the CDC, to avoid bacteria that can cause disease.
