An ode to peanut butter…

Peanut butter, how I love you. You’re creamy and crunchy, savory and sweet, full of plant protein and unsaturated fat. You’re affordable and accessible, nutritious and delicious. How did we get so lucky?

It may sound dramatic, but I’m head over heels in love with peanut butter.

I ate so many peanut butter and banana sandwiches when I was younger. And so many scoops straight out of the jar. Now I love having peanut butter on my daily breakfast toast, in a savory soy dressing, in cookies (like these monster cookies), or, years later, still straight out of the jar.

The fact that peanut butter is so tasty and also so nutritious and affordable is literally the coolest thing to me. Don’t you love when all of those things line up?

Two tablespoons of peanut butter is packed with 8 grams (!!!) of protein, 2 grams of fiber, and 12 grams of unsaturated fat. Eat up!

How to Make Vegan Peanut Butter Monster Cookies

Now that I’ve professed my love for peanut butter, let’s talk about this Vegan Peanut Butter Monster Cookies recipe. I tested these a few times to make sure they were chewy and decadent.

I used white whole wheat flour (whole wheat pastry flour also works) to add nutrients and fiber. I’m also using over 1 cup of peanut butter to hold these monster cookies together and add lots of peanut-y flavor. Use your favorite peanut butter brand—I like to bring my own jar and get it in the bulk section!

If you’re vegan, make sure to find vegan chocolate-covered candies and chocolate chips!

I tested these with non-dairy butter and coconut oil, and by far the winner is non-dairy butter. The coconut oil made them too crispy. Objectively, chewy cookies >>> crispy cookies.
