Instructions

• Preheat the oven to 350°F (175°C). Line an 8-inch square baking pan with parchment paper, leaving some overhang for easy removal.
• In a large bowl, add 2 eggs, 1 cup peanut butter, and ⅓ cup pure maple syrup. If using, add 1 tsp vanilla extract. If your peanut butter is cold or very firm, microwave it for 20–30 seconds before measuring to make mixing easier. Whisk or beat until the wet ingredients are smooth and well combined.
• Add 1 ½ cups rolled oats, ¼ tsp baking soda, 1/2 tsp ground cinnamon (if using), and 1/2 tsp sea salt to the wet mixture. Stir until a thick, evenly combined dough forms.
• Fold in 1 cup chocolate chips if using.
• Transfer the dough to the prepared pan. Use a spatula or the back of a spoon to spread and press the mixture into an even layer. If you like, sprinkle extra chocolate chips or flaky sea salt on top before baking.
• Bake on the center rack for 20–25 minutes, or until the edges are slightly golden and the center appears set (not jiggly).
• Remove from the oven and let the bars cool in the pan for at least 15 minutes. Use the parchment overhang to lift the bars from the pan and place on a cutting board.
• Slice into bars and serve. Store any leftovers in an airtight container.
