Step-by-Step Instructions
Let’s Get Cooking!
Preheat the Oven
Preheat your oven to 375°F (190°C). Get your 9×13 inch baking pan ready by greasing it well and giving it a dusting of flour. This will help the bars come out easily.Mix the Dry Ingredients
In a large mixing bowl, sift together 2½ cups of flour, ½ teaspoon of salt, 1 teaspoon of baking powder, and 1 teaspoon of baking soda. This step is important for a fluffy texture. Set this aside for now.Cream the Sugars and Butter
Now, in a different bowl (I know, I know, more dishes), beat together 1⅓ cups of softened butter, 1 cup of light-brown sugar, ½ cup of dark-brown sugar, and ½ cup of granulated sugar until it’s light and fluffy. This should take about 3-4 minutes.Introduce the Eggs and Vanilla
Mix in the two eggs, one at a time, ensuring they’re well incorporated, then add in 1½ teaspoons of vanilla, 1 teaspoon of cinnamon, and ¼ teaspoon of nutmeg. Stirring frequently helps everything come together nicely.Combine Wet and Dry
Gently fold the dry flour mixture into the butter-sugar-egg mix until just combined. Don’t overdo it, you’re looking for a smooth batter, not a workout!Add Oats and Raisins
Now, time for the fun part! Add in 2 cups of rolled oats and your 1 cup of raisins. Use a spatula or a spoon to stir everything until evenly distributed, like you’re creating a happy little family reunion in the bowl!Spread in Pan
Spread the dough evenly into your prepared pan. Smooth the top, and if you’re feeling fancy, sprinkle a few extra oats or raisins on top for a garnish.Bake Away!
Pop it in the oven for 30 minutes. After about that time, give your pan a little jiggle, if it wobbles in the center, throw it back in for another 5 minutes. You want it set but still soft. The edges should be golden brown while the middle is just firm.Cool Before Cutting
Once done, remove from the oven and let it cool for about 10 minutes before cutting into squares, trust me, this patience is worth it! These are best served warm, but they cool down deliciously too.
