Heat your oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment paper, leaving some overhang on the sides for easy removal, or lightly grease the pan if you don't have parchment.

Add the rolled oats, salt, and cinnamon (if using) to your wet mixture. Stir until everything is evenly incorporated. If you're using any optional add-ins like chocolate chips, raisins, or chopped nuts, gently fold them in now.

Spoon the mixture into your prepared baking pan. Use a spatula or the back of a spoon to press it down firmly and evenly, making sure to spread it into the corners. Smooth the top for an even surface.

Let the bars cool in the pan for about 10 minutes, then use the parchment paper to lift them out onto a wire rack to cool completely. Once fully cooled, cut into 12 bars or whatever size you prefer.
