How to Make Oatmeal Raisin Bars

Now, grab your favorite mixing bowls and let’s get cooking!

Preheat the Oven: Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking pan. Feel free to line it with parchment paper for easy removal.
Mix Dry Ingredients: In a mixing bowl, sift together the flour, salt, baking powder, and baking soda. This step is super important; it aerates the flour and ensures everything mixes evenly.
Beat Butters and Sugars: In another bowl, beat the softened butter and both sugars until light and fluffy. The smell will just start to tantalize your senses, trust me; it’s divine!
Incorporate Eggs: Mix in the eggs one at a time, ensuring they are fully incorporated before adding the next one. Then add in that glorious vanilla extract, cinnamon, and nutmeg.
Combine Dry and Wet Ingredients: Gently fold the dry ingredients into the wet mixture until just combined. Don’t overmix! You want it to be combined but still tender.
Mix in Oats and Raisins: Stir in the rolled oats and raisins, creating a thick, doughy mixture that’s loaded with texture. Seriously, it’s like a hug in a bowl!
Spread in Pan: Spread the mixture evenly into the prepared pan. It might feel a bit thick, but just press it down gently; it will spread while it bakes.
Bake to Perfection: Bake for about 30 minutes, or until golden brown and set. You can check their doneness by giving the pan a little shake; if it wiggles a lot, let it bake a bit more.
Cool Before Cutting: Let the batch cool for about 10 minutes before cutting into squares. If you can resist the temptation to dig in right away it’s hard, I know!

FAQs

Can I use quick oats instead of rolled oats?
Definitely! Just keep in mind that quick oats will make the bar softer and slightly less chewy.

Can I leave out the raisins?
Absolutely! Feel free to swap them for your preferred dried fruit, nuts, or even chocolate chips.

What if I want to reduce sugar?
You can cut back on the sugars by a quarter cup, or even use alternatives like honey or maple syrup, just watch the liquid ratios!

How can I tell when it’s done?
Look for a golden-brown color around the edges, and if you give the pan a gentle shake, it shouldn’t wobble too much.
