Ingredient Notes
- All-Purpose/Plain Flour: Use regular all-purpose flour for this recipe. It can be found in the baking aisle of any grocery store.
- Salt: Regular table salt works perfectly fine for this recipe.
- Baking Powder: Ensure your baking powder is fresh to achieve optimal rise and texture.
- Baking Soda/Bicarbonate of Soda: Ensure your baking soda is not expired for effective leavening.
- Butter: Unsalted butter is recommended to have better control over the saltiness, but salted butter can be used if it’s all you have.
- Light-Brown Sugar: Opt for light-brown sugar to add a subtle caramel flavor to the bars.
- Dark Brown Sugar: Dark brown sugar provides a richer, deeper flavor. If unavailable, you can use an equal amount of light-brown sugar.
- Granulated Sugar: Regular granulated sugar is suitable for this recipe.
- Eggs: Use large eggs at room temperature for better incorporation into the batter.
- Vanilla Extract: Pure vanilla extract adds a delightful aroma and enhances the overall flavor.
- Cinnamon: Ground cinnamon provides warm and comforting notes. Look for it in the spice aisle.
- Nutmeg: Ground nutmeg adds a hint of warmth and earthiness. It can be found in the spice section.
- Rolled Oats: Use old-fashioned rolled oats for the best texture in these bars.
- Raisins: Sweet and juicy raisins provide bursts of natural sweetness. Feel free to substitute them with dried cranberries or chopped dates.
Which Oats Are Best
Oatmeal takes center stage in every oatmeal cookie recipe, yet the varieties and names of oats vary across countries. I’ve incorporated two types of oats commonly found in the United States in this particular recipe. Firstly, American old-fashioned oats, also known as jumbo porridge oats internationally, add a delightful chewiness and a nutty texture reminiscent of a granola bar. Secondly, American quick-cook oats, also referred to as porridge oats or rolled oats worldwide, yield a slightly less textured cookie while still delivering exceptional results. It’s important to note that instant oats should be avoided regardless of your location, as they won’t provide the desired outcome.
Step By Step Instructions
Preheat the oven to 375°F (190°C). Grease and flour a 9×13-inch baking pan, ensuring all sides are coated to prevent sticking.
Sift together 2½ cups of all-purpose/plain flour, ½ teaspoon of salt, 1 teaspoon of baking powder, and 1 teaspoon of baking soda/bicarbonate of soda into a large mixing bowl.
In another large mixing bowl, beat 1? cups of softened butter, 1 cup of packed light-brown sugar, ½ cup of packed dark brown sugar, and ½ cup of granulated sugar until fluffy and well combined.
Add 2 large eggs, one at a time, to the butter-sugar mixture, beating well after each addition. Then, stir in 1½ teaspoons of vanilla extract, 1 teaspoon of cinnamon, and ¼ teaspoon of nutmeg until evenly incorporated.
Gradually mix in the flour mixture until just combined, ensuring not to overmix the batter.
Stir in 2 cups of rolled oats by hand, followed by 1 cup of raisins, distributing them evenly throughout the dough.
Mix into the dough by hand until combined.
Spread the dough evenly into the prepared pan, using a spatula to smooth the top.
Bake for approximately 30 minutes. After 30 minutes, gently shake the pan. If the center jiggles, continue baking and check every 5 minutes until there is no longer any movement.
Once baked, remove from the oven and let the bars cool for 10 minutes before cutting into squares or rectangles.
These Oatmeal Raisin Bars are best enjoyed warm, but they are equally delightful when cooled.
Erren’s Top Tips
- Read the recipe thoroughly: Familiarize yourself with the recipe and its instructions before you begin. This will help you understand the process and avoid any surprises along the way.
- Use accurate measurements: Baking is a science, so measuring the ingredients accurately is crucial. Level off the flour with a straight edge, and use measuring cups and spoons for precise amounts.
- Soften the butter properly: Softened butter should be at room temperature for easy creaming with the sugars. Take the butter out of the refrigerator beforehand, but avoid microwaving it, as it may melt unevenly.
- Cream the butter and sugars well: Creaming the softened ones until fluffy and well combined helps create a light and tender texture in the bars. Beat them together until the mixture becomes light and pale.
- Gradually add the dry ingredients: When incorporating the dry ingredients, such as flour, salt, baking powder, and baking soda, into the butter mixture, do so gradually. This ensures even distribution and prevents overmixing.
- Mix the dough gently: Once you’ve added the dry ingredients, mix the dough just until combined. Overmixing can result in tough bars, so stop mixing as soon as the ingredients are fully incorporated.
- Incorporate oats and raisins by hand: When adding the rolled oats and raisins, switch to a spatula or wooden spoon and fold them into the dough by hand. This helps prevent overmixing and ensures the raisins are evenly distributed.
- Preheat the oven properly: Make sure to preheat the oven to the specified temperature before baking the bars. This ensures they bake evenly and achieve the desired texture.
- Check for doneness: Give the pan a gentle shake after the recommended baking time. If the center of the bars still jiggles, continue baking and check every few minutes until there is no longer any movement. This helps avoid underbaking.
- Let the bars cool before cutting: Allow them to cool in the pan for about 10 minutes before cutting them into squares or rectangles. This allows them to set and makes slicing easier.
FAQs
Can I use instant or quick-cooking oats instead of rolled oats?

Can I substitute the raisins with other dried fruits?
Absolutely! Feel free to experiment with dried cranberries, chopped dates, or even currants for different flavor variations.

While butter offers the best flavor and texture, you can use margarine as a substitute. Keep in mind that the taste and consistency may be slightly different.
