US Customary - Metric

Instructions

Line an 8x8 pan with parchment paper.
Combine the 1 cup creamy peanut butter and ½ cup honey in a glass measuring cup or medium heat-safe mixing bowl. Microwave in 30-second intervals, until bubbles begin to form, whisking between intervals. If your peanut butter is unsalted, add ½ teaspoon kosher salt to this mixture.
In a large mixing bowl, combine 3 cups rolled oats with the peanut butter and honey mixture. Using a wooden spoon, spatula or handheld mixer on low speed, mix until evenly incorporated.
Transfer the mixture to the prepared baking dish and use an additional piece of parchment paper to press the oat mixture into an even layer in the prepared pan. Chill the bars for 10-30 minutes in the refrigerator to allow the bars to be easier to cut into squares.
After chilling, remove the bars from the baking dish. Cut the bars into 12 squares and enjoy.

Notes

Peanut Butter: Use either natural refrigerated or shelf-stable peanut butter for this recipe.

Oats: Use rolled old-fashioned or quick-cooking oats. Do not use steel-cut oats. Be sure your oats are certified gluten-free if needed.

Salt: Feel free to add a pinch of kosher salt, even if your peanut butter is salted to help enhance flavors. Omit altogether if on a low-sodium diet.

Honey: Feel free to replace the honey with maple syrup for a vegan-friendly peanut butter bar.

Storage: Store bars in an airtight container in the refrigerator for up to 5 days.
