Ingredients You’ll Need
- ½ cup salted butter, melted and slightly cooled: This adds richness and ensures a luscious texture. Unsalted butter works too if you prefer to control the saltiness.
- ⅔ cup creamy peanut butter: Choose your favorite creamy variety for the best consistency and flavor. Crunchy peanut butter can also be used for a bit of texture.
- 1 ⅓ cups packed light brown sugar: Brown sugar lends the deep, caramel notes, making these blondies moist and chewy. You can substitute with granulated sugar, but the flavor and texture will be different.
- 2 large eggs, at room temperature: Room temperature eggs blend better and help achieve that perfect chewy texture.
- 2 teaspoons pure vanilla extract: This enhances the sweet flavor; always opt for pure extract for the best taste.
- 1 ½ cups all-purpose flour, spooned and leveled: Proper measuring ensures the right balance. For a gluten-free option, use a 1:1 gluten-free flour blend.
- ¾ teaspoon baking powder: This is crucial for giving the blondies a slight lift while keeping them soft and chewy.
- ½ cup butterscotch chips: These provide a rich, melty sweetness that contrasts beautifully with the nutty flavor of peanut butter.
- ½ cup white chocolate chips: They add another layer of sweetness and creaminess, making every bite delightful.
How to Make Decadent Peanut Butter Blondies
Preheat and Prepare the Pan: Start by preheating your oven to 350°F. Prepare an 8-inch square pan by greasing it or lining it with parchment paper. Leaving some parchment overhanging will make it easier to lift out the blondies once they’re baked.
Mix Dry Ingredients: In a mixing bowl, whisk together 1 ½ cups all-purpose flour and ¾ teaspoon baking powder. This step ensures even distribution of the leavening agent, leading to perfect blondies.
Combine Wet Ingredients: In another bowl, stir together ½ cup melted butter, ⅔ cup creamy peanut butter, and 1 ⅓ cups packed light brown sugar until the mixture is smooth and glossy. This combination brings the rich flavor base for your blondies.
Add Eggs and Vanilla: Incorporate 2 large eggs, one at a time, ensuring each is fully mixed in before adding the next. Then fold in 2 teaspoons of pure vanilla extract. This adds warmth and depth to your batter.
Combine Wet and Dry Ingredients: Gently fold the dry ingredients into the peanut butter mixture until just combined. Be careful not to overmix to keep that soft, chewy texture.
Add Chips: Stir in ½ cup butterscotch chips and ½ cup white chocolate chips, reserving a few to sprinkle on top if you like. This adds delicious pockets of melted sweetness in every bite.
Bake the Blondies: Pour the batter into your prepared pan, spreading it evenly. Bake for 35 to 38 minutes or until the edges are golden brown. A toothpick inserted into the center should come out with a few moist crumbs—this is the sign of perfectly chewy blondies.
Cool and Slice: Allow the blondies to cool completely in the pan. I know it’s tough to wait, but this makes them easier to slice and ensures they keep their shape. Once cooled, use the parchment edges to lift them out and cut into squares.
Enjoy!: Grab a piece, take a moment to appreciate that sweet aroma, and indulge in these decadent treats. You deserve it!
Storing & Reheating
To keep your blondies fresh, store them at room temperature in an airtight container for up to 3 days. If you want to enjoy them longer, refrigerate them for up to a week. For longer storage, feel free to freeze them—just wrap them tightly in plastic wrap and then foil, and they’ll be good for up to 3 months. When you’re ready to enjoy, simply thaw at room temperature or pop them briefly in the microwave to refresh that chewy texture.
Chef’s Helpful Tips
- Be sure your butter isn’t too hot when mixing with sugar; if it is, it can cook the eggs prematurely.
- Room temperature eggs blend more evenly into batters, leading to a consistent texture.
- If you prefer a denser blondie, watch the baking time closely. They should be set and slightly soft but not overly firm.
- Want extra flavor? A sprinkle of sea salt on top before baking enhances the overall taste.
- You can easily make a double batch; just adjust the baking time if you’re using a larger pan.
These Decadent Peanut Butter Blondies are a dreamy treat that everyone will adore! Their warm, melt-in-your-mouth quality, paired with rich flavors, makes them the perfect homemade dessert. Feel free to experiment with the add-ins or enjoy them as is—either way, you’ll be left craving more.
