There are plenty of reasons to make your own protein bars. First, it’s economical! You’ll save a lot of money, particularly if you have a habit of buying single bars one a time. Even better, you can customize your bars to your taste preferences, avoid any allergens, and leave out ingredients you don’t want. You can make a bar with high quality protein, whole grains, real nuts or fruit, flaxseeds, whichever sweetener you prefer, and skip all the long-named chemical ingredients (preservatives and fortifications) that you may not need or want in your snack. Plus, they taste awesome if you have a good recipe! You can also cut the bars into different sizes, depending on how substantial a meal/snack you want the bar to be. These bars provide healthy fats from natural peanut butter and flaxseed. Plus, thanks to whole grain oats, they give you 4 grams of fiber.

    Just made these tonight…didn’t have an 8×8 pan so I put them in cupcake liners and just divided the batter in 6. Had to increase the cooking time by 5 minutes, but they came out awesome! They’re so yummy! Not dry or spongey at all, the peanut butter keeps it very moist! My new fave protein recipe!! Thank you 🙂

    Without trying it, my guess is no. Wouldn’t thicken up the same!
