These Vintage Neiman Marcus Chocolate Chip Oat Cookies, are rich, hearty, and loaded with mini chocolate chips, pecans, and shaved bits of a Hershey bar. The story on this cookie goes way back, both in history and in our family. I’m lucky to have my Nan’s handwritten copy passed down to me.

My vintage inspiration for this cake is from my Nan’s recipe book.
While called the Neiman Marcus cookie, this 90’s version comes from a recipe that circulated via a chain letter, not the official recipe. The cookie became legendary thanks to an urban myth about a customer at Neiman Marcus Cafe who asked for their cookie recipe and was allegedly charged $250 on their credit card, not $2.50 and decided to share it with the public but all a hoax.
In 1997 Neiman Marcus published their own version of an oatmeal cookie recipe which includes the blender oats and espresso powder. Over the years, countless versions have been published, so here is my modern take on it.
Ingredients to make Chocolate Chip Oat Cookies
Dry Ingredients
- All-purpose unbleached flour is made from ground wheat kernels with the bran and germ removed. It has a moderate protein content of 10-12%, making it a versatile option for most baked goods.
- Oats are a whole grain high in fiber and available as whole old-fashioned oats, or quick oats, which are finely cut and partially pre-cooked.
- Baking soda (sodium bicarbonate) is a leavening agent that reacts with acidic ingredients (like lemon juice, buttermilk, or vinegar) creates carbon dioxide gas to make baked goods rise.
- Cornstarch is made from the starchy center of dried corn kernels used as a thickener in sauces and pie fillings, and in baked goods to create a light, tender crumb.
- Pink salt is a type of rock salt found near the Himalayas, that is minimally processed and contains trace minerals.
Wet Ingredients
- Butter is made from churned cream that contains 80% butterfat. European butter is churned longer and has a higher fat content (82%-85%), which is why it yields more flavor.
- Brown sugar is granulated sugar combined with molasses, sold as either light brown sugar (with 3.5% molasses) or dark brown sugar (with 6.5% molasses) for a more robust flavor.
- Sugar is a made by processing the juice of the sugarcane plant. Cane sugar is a natural option that is less processed with a slightly courser texture.
- Eggs are produced by chickens and provide structure and stability in baking, while their proteins trap air, creating natural leavening.
- Vanilla provides warm notes of caramel and spice, enhancing the depth of flavor in baked goods. Choose a pure, all-natural extract made from real vanilla beans with at least 35% alcohol.
Mix-Ins
- Semi-sweet chocolate chips are typically the best choice because they balance the sugar. Milk or dark chocolate chips or any size like regular chocolate chips, mini-chocolate chips or chocolate chunks, will work in this recipe.
- Pecans are a tree nut that grown on pecan trees in the United States and Mexico. They add texture and sweet nuttiness flavor to baked goods.
- chocolate: Use a creamy milk chocolate bar for the perfect balance when paired with the semi-sweet chocolate chips. A standard bar is about 1.5 oz., so you’ll need 2 bars to get close, or use 1 XL Hershey bar (4.4 oz.) for a closer match.
Make your own Ingredients
Vanilla: Purchase Grade B vanilla beans (also called extract-grade), which have less moisture and a more concentrated flavor. Place 8 oz. of bourbon (or vodka) in glass bottle or jar. Split 5-7 vanilla beans down the middle and add to bottle. Let it sit for 3-6 months in a cool, dark place. As you use it, continue to replace the bourbon and add more beans as it keeps for many years.
Dietary Substitutions
For the past 12+ years, I have owned an all-natural specialty bakery converting conventional recipes to gluten free, vegan, wholesome, etc. You can read more about my pro-baking here.
Here are a few basic tips when converting conventional recipes into specialty baked goods.
- Shelf Life: Specialty baked goods tend to dry out faster and have a shorter shelf life than conventional baked goods. Store in an airtight container on counter for 1 – 2 days. For longer storage, freeze up to 6 months. Avoid refrigerating, as it can dry out baked goods.
- Let Batter Rest: Alternate flours can be dense or slightly gritty compared to white flour, so be sure to let the batter rest at least 15 minutes or overnight in the refrigerator before baking. This allows the flour to fully hydrate and produce a lighter, tender crumb.
- Oven Temperature: Alternative flours are delicate and tend to brown faster before the center is cooked through. Reduce oven to 325° and bake “low and slow,” adding a few extra minutes of bake time if needed.
Gluten-Free (no gluten)
- Flour: Swap out the flour with a premium gluten-free flour such as King Arthur Measure for Measure or use a homemade gluten-free flour blend. Be sure the flour blend contains xanthan gum or add 1/4 tsp. to 1/2 tsp. per every 1 cup of flour to the recipe.
- Hydration: Gluten free flours can make baked goods dense. Add 1 tablespoon of additional extra liquid (the same liquid called for in the recipe) to help lighten the texture.
- Fat: Add up to 1 to 2 Tbsp of additional fat, such as butter or oil to the recipe.
Vegan/Dairy Free (no animal products)
- Butter: Use unsalted vegan butter sticks such as Violife for best flavor and texture.
- Dairy: Replace dairy with unsweetened plant based milk such as oat, coconut or almond milk.
- Eggs: Replace each egg by adding 1 tsp. baking soda to the batter, then pour 1 Tbsp. white vinegar over it. Add the vinegar last though, to keep the leavening reaction.
- Fat: Add up to 1 to 2 Tbsp of additional fat like oil or vegan butter to the recipe.
- Use dairy-free chocolate chips Nestle plant based chips.
Keto (low carb, high fat)
- Flour: Swap the white flour for almond flour or coconut flour.
- Sweetener: Replace sugar with Lakanto Monkfruit Sweetener which calls for a 1:1swap that mimics granulated sugar.
- Dairy: Replace dairy with unsweetened plant based milk such as coconut or almond milk.
- Hydration: Almond flour can make baked goods dense. Add 1 -2 tablespoons of additional extra liquid (the same liquid called for in the recipe) to help lighten the texture. Add 1 additional egg to help bind the batter.
- Fat: Add up to 2 Tbsp of additional fat, such as butter or oil to the recipe.
- Use no-sugar chocolate chips such as Lily’s.
Wholesome (minimally processed)
- Flour: Swap out 1/3 to 1/2 of the white flour with King Arthur white whole wheat flour or King Arthur 100% whole wheat flour or Bob’s oat flour.
- Sweetener: Replace white sugar with maple syrup or honey. Use 3/4 c. honey for every 1 c. sugar. You can also swap out the white sugar with 1:1 swap using natural cane sugar, coconut sugar or date sugar.
- Dairy: Replace dairy with unsweetened plant based milk such as oat, coconut or almond milk.
- Lower Fat: For every 1 c. of butter, use 3/4 c. heart-healthy oil (like canola or extra-light olive) OR 1/2 c. unsweetened applesauce + 1/2 c. oil.
Allergen Free (none of the 9 allergens)
- Flour: Swap out the flour with a premium gluten-free flour such as King Arthur Measure for Measure or use a homemade gluten-free flour blend that does not contain tree nuts or soy. Be sure the flour blend contains xanthan gum or add 1/4 tsp. to 1/2 tsp. per every 1 cup of flour to the recipe. Here is a list of some other gluten-free flours to try.
- Butter: Use unsalted vegan butter sticks such as Violife for best flavor and texture. Add up to 1 to 2 Tbsp of additional fat like oil or vegan butter to the recipe.
- Dairy: Replace dairy with unsweetened plant based milk such as oat or coconut milk. Check the labels to make sure they are soy-free and nut-free.
- Eggs: Replace each egg by adding 1 tsp. baking soda to the batter, then pour 1 Tbsp. white vinegar over it. Add the vinegar last though, to keep the leavening reaction.
- Nuts: Omit all peanuts and tree nuts (almonds, brazil nuts, cashews, hazelnuts, macadamia nuts, pecans, pine nuts, pistachios, or walnuts.
Storage & Freezing
Pre-baked cookies:
- You can make the batter and store until ready to bake.
- Short-term, scoop the batter into cookie pucks/balls and place in storage container until use.
- Long-term, place all of the mixed batter into a ziploc bag or storage container and let the batter come to room temperature before scooping into cookie pucks/balls.
Baked cookies:
- Store baked cookies in airtight container on counter 1-2 days.
- Seal in in freezer safe container for up to 6 months. Place cookies in layers lined with parchment paper. You can also individually heat seal cookies and place them in a larger container.
- To thaw frozen cookies, allow them to come to room temperature before opening the container.
FAQ’s
For thick cookies you need to chill the batter and bake on Silpat baking mat to ensure less spread. For thin and crispy cookies, scoop out cookie dough and put straight into the oven.
Yes, if you are looking for more flavor, toast the nuts before adding to the cookies. Rough chop them in mini food chopper and put on a baking sheet and bake at 350° for 5 minutes.
If you don’t have quick oats, you can make them by putting old-fashioned oats into a small food processor and pulse into a course texture.
Grate the chocolate using a box grater, so you can choose the size of shreds. A microplane will make a powder. Freeze the chocolate bar a few minutes before use, so that it remains firm while grating.
