Making your own protein bars may sound like a project, but this recipe comes together quickly and doesn’t require turning on the oven. Its greatest appeal, though, is how it combines the crackle of nuts and the creaminess of nut butter with earthy maple syrup. A fat pinch of salt and a touch of pepper bring out the nuts’ toasty bittersweetness. The black pepper sharpens the syrup’s caramel roundness, but try ground chipotle or other dried chiles for a smoky heat. There’s plenty of salt, but if you want even more, sprinkle flakes on top before chilling. Feel free to customize the nuts and seasoning: Just be sure to keep the ratios the same.

Preparation

  1. Step 1

    Line the bottom and sides of a 9-inch square baking pan with parchment paper.

  2. Step 2

    Bring the syrup, salt and pepper to a boil over medium-high in a large saucepan, stirring occasionally. Boil until thickened to the consistency of honey, about 2 minutes. Turn the heat down to low, add the almond butter, and stir until smooth and bubbles just start to pop, about 1 minute longer. Turn off the heat.

  3. Step 3

    Add the oats, nuts and seeds, and stir until everything is very evenly coated. Smash and scrape the mixture as needed to get everything coated; the mixture will be quite stiff.

  4. Step 4

    Scrape the mixture into the parchment-lined pan and press firmly into an even layer. Refrigerate until stiff, at least 1 hour and up to overnight.

  5. Step 5

    Use the parchment to slide the slab out of the pan and onto a cutting board. Cut into 12 even bars. Wrap individually, if you’d like. The bars will keep in an airtight container at room temperature or in the refrigerator for up to 2 weeks.

Tips
  • Peanut butter binds ingredients best, but almond butter works as well. You just need more of it to glue the bars together. Sunflower seed butter can be used, but the bars may crumble. Tahini isn’t quite sticky enough to do the job. All-natural varieties, in which the only ingredients are the nuts or seeds and salt (and, sometimes, oil), deliver the nuttiest flavor.
  • You can use any variety or combination of your favorite nuts. Just make sure they’re raw, or natural, without added oils or salt. Also make sure that they’re chopped small enough so that the bars will hold. Pre-chopped walnuts and pecans and sliced almonds make this recipe come together even more quickly.

Delicious, but very misleading to call them protein bars. Lots of calories (~300) to get to less than 10g of protein.

Genevieve

I tested these with regular rolled oats and they're very tasty, but because they're larger and thicker than quick-cooking oats, the bars don't hold together easily. If you're ok with the bars crumbling a bit, you definitely can use rolled oats!

Could you use honey in the first place (or better yet, Lyle's syrup) rather than boiling maple syrup until it has the consistency of honey?

Janet

This recipe didn't work for me at all. I was left with a pile of crumbles on the cutting board after I removed everything from the pan. The crumbles were tasty, but not even chunky enough to use as granola. I had pressed the ingredients into the pan with the back of a large serving spoon, but it didn't help.

I substituted all the nuts and rolled oats for 1/2 cup of muesli and also added protein powder. I agree with the comments that this is not a protein bar but it's tasty and I was able to reduce the overall calories to around 150 a serving. next time I'll use either honey or less maple syrup. I don't love the syrup flavor but it does make it a sweet treat that isn't as bad as eating a bunch of candy or ice cream.

Would advise against making these bars. They did not hold together, no matter how much almond and peanut butter we added. Consulted with several excellent bakers for help, and am now finally throwing the ingredients out. Agree, it was like sawdust. Please redo the wet ingredients or remove from the file.
