Ingredient Notes

A complete list of ingredients with amounts and full instructions is located in the printable recipe card below. This section covers ingredient and substitution considerations.

Visual of all ingredients needed for making peanut butter oatmeal chocolate chip cookies.
  • Banana: Use a ripe banana, it doesn’t have to be overripe, brown or mushy, just ripe or slightly overripe with a few brown spots is perfect.
  • Peanut Butter: Use natural peanut butter. Substitute with almond butter, cashew butter or for nut-free cookies, sunflower seed butter or tahini.
  • Almond Milk: I like unsweetened almond milk but any plant-based milk works.
  • Maple Syrup: Can be substitute with agave syrup or honey (not vegan)/
  • Rolled Oats: You’ll either need oats flour and rolled oats or enough rolled oats to make oat flour. Quick oats are also fine if that’s all you have.
  • Chocolate Chips: I like Enjoy Life or Camino but any dairy-free chocolate chips, morsels or chunks work great. For an extra decadent cookie, try using half chocolate chips and half chocolate chunks! If you want to skip the chocolate, you can substitute raisins, cranberries or chopped dates.

Step-by-Step Instructions

Before You Start: Preheat the oven to 350 F and line a baking tray with parchment paper.

Step 1. If you don’t have oat flour on hand, make that first by adding 1.25 cups of oats to a blender or food processor and blending into a fine flour-like consistency.
