Ingredients for this Crumbl hazelnut mudslide cookie recipe

Here are the ingredients you will need to make these. Make sure to scroll down to the recipe card for the full detailed ingredient measurements.

• Butter– You can use salted or unsalted butter as long as it is softened.
• Imperial Sugar brown sugar & Imperial Sugar granulated sugar– This cookie uses two types of sugar to really bring out the depth of flavor as well as keep the cookie extra moist.
• Egg– Use an egg at room temperature for this cookie recipe.
• Vanilla extract– I know vanilla extract sounds odd when making a chocolate cookie, but it elevates it so much!
• Flour– AP flour works great for this recipe.
• Cocoa powder– Dutch-processed cocoa powder is best for this cookie recipe but if you don’t have it and don’t want to wait until you get it, use regular cocoa powder.
• Baking soda– This is the leavening agent of this recipe.
• Salt– Always use a little salt in your baked goods to bring out the sweetness of the cookie even more.
• Hazelnut– The hazelnuts are used for the outside of the cookie and they add a delicious nutty flavor and a crunchy texture.
• Nutella– You can use Nutella or any hazelnut spread for this part.

WHY IMPERIAL SUGAR?

For this recipe, I am using Imperial Sugar because I wanted the best results possible. When making copycats, I think using high-quality ingredients will make your baked good just as good and maybe even better than the real thing and that’s why I went with Imperial Sugar!

The fine Imperial Sugar granulated sugar mixes so well with the butter to create a lighter cookie base, perfect for holding your banana cream pudding on top!

Frequently asked questions – FAQ

How to store these cookies?

You can store these cookies in an air-tight container for up to 4 days at room temperature.

I also like to store these in the fridge so they can last longer. Keep them in an airtight container for up to 7 days. Warm them up in the microwave when you’re ready to enjoy these so that they’re ooey-gooey again.

Can I freeze these Crumbl hazelnut mudslide cookies?

Yes! Make sure to flash freeze these cookies if they are topped with the Nutella though so that it doesn’t become a giant block of cookie afterward.

Here’s how you can flash freeze these cookies. Place them on a baking sheet or a plate and freeze for an hour or two then transfer to an airtight container and freeze for up to 2 months.

Once ready to enjoy these, thaw them on a late surface in the fridge overnight or on the countertop for a few hours.

How to make smaller mudslide cookies?

To make these cookies smaller, make 14 smaller cookies instead of 7 larger ones. Fill them up with about 1-2 tsp or Nutella, and bake them at 350F for 8 minutes.

Can I use something other than Nutella?

Absolutely! If you don’t have Nutella or don’t want to use Nutella, you can use any other Hazelnut chocolate spread.

There are even versions that are nut-free which will make this cookie a lot more allergy-friendly. Of course, don’t roll the cookie dough in the hazelnuts if you want to make this recipe nut-free.
