Peanut Butter Oatmeal Cookie Shake

Well, hello gorgeous! It’s already been one hot summer here in Chicago and I’ve been dreaming about all my healthy smoothie recipes to sip on. In fact, my daily summer breakfast of choice is typically a smoothie or shake because it’s refreshing, there’s no cooking involved, and I can make them as healthy as I’d like.

Lately, I’ve been obsessed with recreating smoothies that taste like cookies. Because why the hell not. Remember my tahini snickerdoodle smoothie? Everyone agrees that it totally tastes like a snickerdoodle cookie. And now, I’m here to introduce my latest and greatest creation: peanut butter oatmeal cookie shake…or smoothie. Call it what you want, but I liked the sound of shake better.

Peanut butter oatmeal cookie shake ingredients

This easy, healthy peanut butter cookie shake is made with under 10 ingredients that you might already have in your fridge and pantry. Plus, it’s naturally sweetened without any banana! You’ll need:

• Medjool dates: I love using dates as a natural sweetener in smoothies, shakes and desserts. You’ll only need three and they pack in a great fiber boost! Feel free to only do 2 if you prefer it less sweet.
• Almond milk: feel free to use any milk you’d like. I prefer an unsweetened vanilla almond milk, but coconut, cashew or oat milk would also be super yummy.
• Frozen cauliflower: yes, this oatmeal cookie shake recipe has cauliflower in it! You’ll get a nice boost of veggies but won’t be able to taste the cauliflower at all. PROMISE!
• Oats: for that delicious oatmeal cookie flavor. I recommend using rolled oats or quick oats and feel free to use gluten free. Do not use steel cut oats, they will not blend properly.
• Peanut butter: you’ll love the creamy peanut butter blended with all of these ingredients. You can also use any other nut butter you’d like.
• Vanilla extract: for a little additional flavor boost.
• Cinnamon: the hint of cinnamon really brings out the oatmeal cookie flavor.
• Salt: a pinch of salt makes this taste AMAZING.

The result is a creamy shake that tastes just like a peanut butter oatmeal cookie, with a pinch of sea salt on top. DAMN GOOD INDEED.

Optional peanut butter cookie shake nutrition boosters

• Flaxseed meal: this is one of my favorite ingredients to add to shakes and smoothies for a little boost of fiber and minerals. It’s especially great for nursing mamas as flaxseed can help increase milk supply. Usually a tablespoon is plenty! Here’s a brand I love.
• Chia seeds: add in a tablespoon of chia seeds for a boost of healthy fats and fiber.
• Hemp seeds: feel free to throw in those hemp seeds lurking in your cupboard for a boost of healthy fats, omegas and minerals.
• Organic spinach: if you’re looking to get more greens in your shake or smoothie, try adding a few cups of spinach. It may turn the smoothie a slightly off-putting color, but you won’t be able to taste the spinach at all.
• Greek yogurt: add a boost of protein with a scoop of Greek yogurt (or your favorite dairy free yogurt). You may have to reduce the almond milk to 3/4 cup in this recipe when adding yogurt.
• Protein powder or collagen peptides: another great way to add some protein. I recommend a plain or vanilla flavored protein powder in this recipe. Here is a great plant-based option.
• Cacao powder: this would add a delicious, chocolate-y flavor to the peanut butter cookie smoothie along with a great source of antioxidants. I recommend 1 tablespoon.

Tips for making this oatmeal cookie shake

Here are a few of my favorite tips for making this oatmeal cookie shake creamy and delicious:

1. Using frozen cauliflower as it helps keep the smoothie cold and thick. Sometimes ice doesn’t blend as well, so it’s best to skip unless absolutely necessary.
2. Don’t be afraid to add more liquid if your smoothie is too thick or won’t fully blend. High powered blenders tend to blend frozen ingredients much better, so if you have a regular or personal size blender, you may need to add more milk.
3. Start the blender on low speed, then gradually increase the speed to high to help blend all ingredients. End with the blender on low speed.
4. Add your favorite toppings like extra peanut butter, a sprinkle of oats, the above mix-ins or a handful of homemade granola!

How to soften your dates

You’ll simply soak your pitted dates in 1 cup of warm water for at least 5 minutes. This will help them soften up and make sure that you can easily blend them into the shake.
