Ingredients Notes
To make these cookie bars, you’ll need self-rising flour, brown sugar, and your choice of melted butter or coconut oil. For those who wish to adjust the sweetness, consider using dark brown sugar for a deeper flavor. If you can’t find self-rising flour, you can make your own by adding 1 ½ teaspoons baking powder and ¼ teaspoon salt per cup of flour. Be sure to melt the butter or coconut oil completely for a smooth and even mixture.
Recipe Steps
Step 1
Preheat your oven to 350°F (175°C). Grease a 9×9 inch baking pan or line it with parchment paper to prevent sticking.
Step 2
In a large mixing bowl, combine 2 cups of self-rising flour and 1 cup of brown sugar. Use a wooden spoon or spatula to mix the dry ingredients thoroughly.
Step 3
Slowly add 1 cup of melted butter or coconut oil into the flour mix. Stir until everything is well combined and a dough forms.
Step 4
Transfer the dough into the prepared baking pan. Use a spatula to spread it evenly, pressing it gently to ensure a smooth top.
Step 5
Bake for 20-25 minutes or until the edges turn golden brown. Let it cool in the pan for 10 minutes before slicing into bars.
Storage Options
To keep these cookie bars fresh, store them in an airtight container at room temperature for up to five days. For longer storage, freeze them individually wrapped in plastic wrap and placed in a zip-top bag for up to three months. Simply thaw them at room temperature for about an hour before enjoying or zap them in the microwave for a few seconds for a warm treat.
Variations & Substitutions
Feel free to customize these cookie bars to your liking. Substitute the brown sugar with honey or maple syrup for a different sweetness profile. Add a handful of chocolate chips, dried cranberries, or chopped nuts for a unique twist. For a vegan version, choose coconut oil and a plant-based baking spread instead of butter.
Serving Suggestions
These versatile cookie bars are perfect for various occasions. Serve them at room temperature with a glass of cold milk for a classic snack. Dress them up with a scoop of Ice Cream and a drizzle of caramel sauce for an indulgent dessert. They also make a delightful addition to lunchboxes or picnic baskets on sunny days in the park.
Frequently Asked Questions
Can I make these cookie bars gluten-free? Absolutely! You can substitute the self-rising flour with a gluten-free baking mix that includes similar leavening agents. Ensure the mix is labeled ‘gluten-free’ to cater to those with dietary restrictions.
What if I only have regular flour? No worries! You can create a homemade self-rising flour mix with all-purpose flour. Simply add 1 ½ teaspoons of baking powder and ¼ teaspoon of salt for every cup of all-purpose flour to achieve similar results.
How can I tell if the cookie bars are ready? Your cookie bars are ready when the edges are golden brown and have pulled away slightly from the sides of the baking pan. A toothpick inserted in the center should come out mostly clean, with a few moist crumbs.
