Ingredients and substitutions
Here are a few quick notes about the ingredients in this recipe. You can see a complete list of ingredients and instructions in the recipe card below.
Ground flaxseed - Mixed with water, ground flaxseed forms a "flax egg," gelling to work as a binder for our egg replacer.
Gluten-free oat flour - If you are Celiac or gluten-intolerant, ensure that you are using certified gluten-free oat flour or certified gluten-free oats to make your own homemade oat flour.
Adding fiber, antioxidants, and more protein to the mix, oat flour supplies whole-grain goodness.
Gluten-free oats - As with the oat flour, make sure you choose certified gluten-free oats if needed. Rolled oats (also known as old-fashioned oats) give our bar a great chewy texture.
Avoid quick oats as they can create a gummy texture.
Peanut butter - All-natural is best for this recipe as its simple ingredients don't have any added sugar or oils.
Almond butter or cashew butter can be substituted but will alter the flavor profile.
Organic cane sugar - This vegan-friendly less refined sugar helps sweeten in combination with coconut sugar.
Coconut sugar - In lieu of brown sugar or light brown sugar, this unrefined sweetener adds depth of flavor.
You can always sub in more organic cane sugar in its place. Do note that cane sugar is sweeter than coconut sugar.
Vanilla extract and ground cinnamon - Pure vanilla extract helps round out the sweet flavors.
Dairy-free chocolate chips - Use your favorite vegan chocolate chips for these chocolate oat bars, mini or regular!
You could even throw some white chocolate chips in there as well.
Before you start: Preheat the oven to 350 degrees Fahrenheit. Grease a 9x9 inch pan with coconut oil and line with parchment paper. Prepare your flax eggs and set aside.
Step 1: In a medium bowl, combine oat flour, baking powder, and salt.
Step 2: In a large mixing bowl, cream peanut butter, cane sugar, and coconut sugar together with an electric mixer until light and fluffy. Mix in flax eggs, and almond milk followed by vanilla extract.
Step 3: Stir in the dry ingredients with the pb mixture. Mix until combined (use your hands if needed). Fold in the chocolate chips.
Step 4: Press the batter into the prepared baking pan. Use an extra piece of parchment paper to press and pack into an even layer.
Bake bars for 25-28 minutes until a toothpick comes out clean. The top should start turning a golden brown.
- For best results, allow bars to cool completely to room temperature before removing them from the pan and slicing.
- Feel free to press in extra chocolate chips on top of the bars before baking or sprinkle flaky sea salt.
- Do not overbake bars as they will become crumbly.
- Add your favorite mix-in's with the chocolate chips like chopped nuts, seeds, or dried fruit!
Store these oatmeal peanut butter bars in an airtight container at room temperature for 2-3 days. You can also wrap them individually in plastic wrap for on-the-go snacks.
They can be stored in the refrigerator for 4-5 days.
If in a glass jar, remove the lid and microwave the jar of peanut butter in short intervals, around 10-15 seconds at a time. Be cautious not to overheat it, as the jar can become hot and may become too runny. Stir between intervals to distribute the heat evenly.
No, rolled oats and quick oats are not the same, although they both come from the same source—oat groats. Rolled oats are made by steaming oat groats and then flattening them with large rollers. Quick oats, or instant oats, undergo additional processing steps. They are pre-cooked, then rolled into thinner flakes.
Yes! In place of eggs, ground flaxseed is used and there are no dairy or animal ingredients.
