Why Should You Make This Recipe

I love making overnight oats for a quick and easy, filling and protein filled breakfast. My Peanut Butter Overnight Oats, Apple Cinnamon Overnight Oats, Tiramisu Overnight Oats, Blueberry Overnight Oats and Pumpkin Overnight Oats are overnight oats recipes that I absolutely adore. This protein overnight oats recipe is another healthy, protein packed breakfast recipe I know you will love just as much as I do. 

  • Quick and healthy dessert for breakfast. This chocolate chip overnight oats recipe takes about 5 minutes to assemble using a handful of simple ingredients. Simply mix everything together and allow the oats to soak overnight. The result is a delicious, healthy and hearty breakfast that tastes like cookie dough.  
  • Perfect for meal prep. Overnight cookie oatmeal is perfect for making at the beginning of the week and enjoying for a healthy, filling and delicious breakfast for the next 3 - 4 days. 
  • You need an eggless, gluten free and high protein breakfast idea. Oats are filled with fiber and slow digesting, complex carbs. Add chia seeds, milk, some sweetener and protein powder and you’ve got a simple and filling breakfast that tastes like cookie dough!

Ingredients

This cookie dough oatmeal recipe requires only a handful of basic pantry ingredients which makes them perfect for busy mornings. Here’s what you will need.

Gather Oats, chia seeds, milk, yogurt, protein powder, nut butter, maple syrup and chocolate chips.

Gather oats, chia seeds, milk, yogurt, protein powder, nut butter, maple syrup and chocolate chips.

Substitutions 

Here are my recommended substitutions to make this cookie dough overnight oats if you need them.

  • Oats: Heartier types of oats such as old fashioned, rolled oats or steel cut oats are better options for overnight oats. If needed, use gluten free oats to make these overnight protein oats gluten free. 
  • Chia Seeds: I like adding chia seeds to overnight oats for a thicker and creamier consistency. Feel free to omit or use flax seeds if you like. 
  • Milk: Use any milk you like. Plant based milk also works well in this recipe if you would like to make these overnight oats vegan. For an extra boost of protein, use protein milk. 
  • Yogurt: Use a good greek yogurt you like. If you would like to make this vegan, use a plant based yogurt. 
  • Protein Powder: Use your preferred vanilla or chocolate protein powder. I personally love this one. 
  • Maple Syrup: Honey or agave work well to sweeten these protein oats. 
  • Nut Butter: Feel free to use your preferred runny or creamy nut butter or dried nut butter powder. 
  • Chocolate Chips: Adding some chocolate chips to the overnight oats gives the taste of chocolate chip cookie dough. Feel free to use chocolate chips or any other mix-ins that remind you of your favorite cookies.

How To Make

Learn how to make cookie dough overnight oats in a few easy steps.

  1. Grab 2 containers with lids to prepare the protein overnight oats recipe. Add 2 tablespoons rolled oats to each container. This is to give the overnight oats a thicker texture. Feel free to skip or add all the oats (1 ½ cups total) straight into the blender. Add the milk, yogurt, protein powder, maple syrup, rolled oats, chia seeds and nut butter to a blender. Blend the ingredients together on low or medium for about 30 - 60 seconds or until your desired texture. 
  2. Evenly pour the cookie dough oats mixture into each of the containers.Add chocolate chips and mix well. Cover the containers and transfer the overnight protein oats to chill in the fridge for at least 4-6 hours or overnight. When it’s time to serve, top the cookie dough oats with your preferred toppings and enjoy. I love topping mine with more chocolate chips.

How To Make Ahead, Store and Serve

  • Make Ahead: Cookie overnight oats are perfect for meal prep. Prepare the oats according to the recipe through to the chilling step. The oats will keep well in the fridge for up to 3 days. Wait to top the overnight oats until right before serving. 
  • Store: Place the overnight cookie dough oats in an airtight container in the fridge for up to 3 days.
  • Serve: Top the overnight chocolate chip cookie oats with your preferred toppings. To keep them more in line with chocolate chip cookie dough, I recommend adding more chocolate chips. You can also add a dollop of lightly sweetened yogurt, fruit like berries, a drizzle of nut butter, chopped nuts and/or a dusting of cinnamon right before serving.

M’s Expert Tips

  • Mix the ingredients directly into individual containers. The easiest and more precise way to make overnight oats is to mix the dry and wet ingredients directly into the individual containers.
  • For more cookie dough flavor use protein powder. Use a vanilla flavor, chocolate flavor or cookie dough flavored protein powder to help give these overnight oats even more chocolate chip cookie flavor. 
  • Use the right kind of oats. Rolled oats, old fashioned oats or steel cut oats are good for making overnight oats. Use gluten free oats if needed. 
  • Use a blender. Part of what helps to create the cookie dough texture is blending the oats so they are a finer texture. If you want to skip the blender, use quick cooking oats in place of the rolled oats. 
  • Add chia or flax seeds. The addition of chia or flax seeds adds healthy omega-3 fats and creates a thicker more pudding like consistency to the overnight oats. 
  • Add toppings before serving. Top these cookie overnight oats with your preferred toppings. To keep them more in line with chocolate chip cookie dough, I recommend adding more chocolate chips. You can also add a dollop of lightly sweetened yogurt, fruit like berries, a drizzle of nut butter, chopped nuts and/or a dusting of cinnamon right before serving.

FAQs

Does cookie dough overnight oats actually have cookie dough in it?

No, this recipe for cookie dough overnight oats takes the same flavor notes as an edible cookie dough and creates a healthy oatmeal based breakfast or snack. To create the texture of cookie dough, oats are blended with other ingredients. Vanilla extract, vanilla protein powder and chocolate chips help to create the chocolate chip cookie dough flavor.

What can I add to overnight oats to increase protein?

Add a scoop of protein powder, greek yogurt, nut butter and/or protein milk to boost the protein content for any overnight oats recipe.

Are overnight oats actually healthy?

Yes, overnight oats have a whole host of benefits to keep your body healthy. Soaking the oats breaks down starches and phytic acid, making the nutrients and vitamins easier to absorb. The addition of chia seeds adds a boost of omega-3. Adding a scoop of protein powder adds more satiating protein to keep you fuller for longer. Top these high protein oats with fruit for even more vitamins and minerals.
