What You’ll Need
Here are the ingredients you’ll need to make these homemade cookie bars at home. See the recipe card located at the bottom of the page for full details and instructions.
- Salted Butter– For most of my recipes I use salted butter, unsalted works fine too.
- White Chocolate Chips– Find the white chocolate chips in the baking isle of the grocery store.
- Brown Sugar– I used light brown sugar for the blondies, dark brown sugar works as well.
- Large Eggs– For consistency, I use large eggs in all of my cooking and baking.
- Pure Vanilla Extract- Use pure vanilla for best tasting results.
- Sour Cream– Use full fat sour cream for the recipe.
- All-Purpose Flour– Flour is the main dry ingredient in the blondies.
- Baking Soda– Baking soda helps the blondies rise during baking.
- Kosher Salt– Kosher salt is a coarse salt commonly used in cooking and baking. I prefer it over table salt.
- Mini Chocolate Chips– If you can’t find mini chocolate chips, regular are fine too.
- Creamy Peanut Butter– Any favorite brand of peanut butter is fine.
