Step‑by‑Step Instructions for Peanut Butter Blondies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms up, take an 8×8 baking dish and line it with parchment paper, allowing some overhang for easy removal later. Lightly grease the parchment to ensure that your fudgy Peanut Butter Blondies will come out smoothly once baked.
Step 2: Mix the Base
In a large mixing bowl, combine the melted unsalted butter and light brown sugar. Use a sturdy whisk or spatula to mix these two until they’re fully blended, creating a smooth, glossy mixture. This should take about 2-3 minutes, and the color will deepen as the sugar dissolves into the butter, indicating you’re on the right track.
Step 3: Add Wet Ingredients
Now, crack in the large egg and pour in the vanilla extract, mixing well to incorporate. It’s important that you stir vigorously for about 1-2 minutes until the egg is fully integrated, and the mixture is slightly thickened and cohesive. This step ensures that your Peanut Butter Blondies have a tender texture that melts in your mouth.
Step 4: Fold in Peanut Butter
Next, add the peanut butter into the bowl, stirring until your mixture reaches a creamy consistency. Use a spatula to scrape down the sides of the bowl to make sure everything is well combined. This will typically take another minute of mixing, and you’ll notice a rich, nutty aroma that fills the air, signifying that you’re almost there!
Step 5: Mix Dry Ingredients
Incorporate the salt and all-purpose flour into the peanut butter mixture. Gently fold the flour in using a spatula, being careful not to overmix. Aim for just enough blending until the flour disappears; the dough will be thick and sticky, which is exactly what you want for your fudgy Peanut Butter Blondies.
Step 6: Spread the Batter
Transfer the blondie batter into your prepared baking dish. Use the back of a spatula to spread the mixture evenly, ensuring it fills the corners of the pan. This should take about 1-2 minutes of gentle spreading. The batter will be thick, so take your time to create an even surface that will bake beautifully.
Step 7: Bake to Perfection
Place the baking dish in your preheated oven and bake for 20-25 minutes. Keep an eye on your blondies; they’re done when the edges are golden, and a toothpick inserted in the center comes out with a few moist crumbs, indicating that lovely fudgy consistency. Remember, do not overbake for a gooey center!
Step 8: Cool and Slice
Once baked, remove the dish from the oven and let it cool completely in the pan for about 15-20 minutes. After cooling, lift the blondies out using the parchment overhang and slice them into squares. The rich aroma of the freshly baked Peanut Butter Blondies will have everyone eagerly awaiting their first bite!

Expert Tips for Peanut Butter Blondies
Perfectly Fudgy: Don’t overbake your blondies; a slightly gooey center guarantees that melt-in-your-mouth experience you’re after.
Melted Butter Magic: Always use melted butter for density; softened butter can lead to a more cake-like texture instead of the desired fudginess.
Mix-Ins Galore: Want to customize your peanut butter blondies? Adding chocolate chips or toffee bits enhances flavor without overwhelming the peanut butter essence.
Mind the Pans: If using a larger pan, reduce the bake time slightly; thinner blondies will cook faster and may dry out if overbaked.
Cool Down: Allow the blondies to cool completely before slicing to ensure clean cuts and retain that delightful fudgy texture.
Make Ahead Options
These fudgy peanut butter blondies are perfect for meal prep enthusiasts looking to save time during busy weeks! You can prepare the batter up to 24 hours in advance. Simply follow the recipe up to the point of spreading the batter in the baking dish, then cover it tightly with plastic wrap and refrigerate. When you’re ready to bake, take the batter out and let it sit at room temperature for about 15 minutes before baking to ensure even cooking. This way, you’ll still achieve that irresistible fudgy texture and rich peanut butter flavor, making your dessert just as delicious as if baked fresh!

Peanut Butter Blondies Recipe FAQs
How do I choose the right peanut butter for my blondies?
Absolutely! For the best flavor, I recommend using creamy peanut butter to achieve a smooth texture. If you prefer a bit of crunch, feel free to swap in crunchy peanut butter. Just make sure that it’s a brand you enjoy eating on its own, as that flavor will shine in your blondies!
What’s the best way to store leftover peanut butter blondies?
You can store your peanut butter blondies in an airtight container at room temperature for up to 1 week. If you’re looking to keep them longer, simply pop them in the refrigerator for up to 2 weeks. Just ensure they’re well-wrapped to maintain their moistness and chewiness!
Can I freeze peanut butter blondies? If so, how?
Absolutely! To freeze your peanut butter blondies, start by allowing them to cool completely. Then, wrap each piece individually in plastic wrap to keep them fresh. Place the wrapped blondies in a freezer-safe bag or container, and they’ll last in the freezer for up to 3 months. When you’re ready to enjoy, simply thaw at room temperature, and you can warm them in the microwave for about 10-15 seconds for that fresh-baked taste!
What should I do if my blondies turn out too dry?
If your blondies end up dry, it might have happened due to overbaking—so make sure to keep an eye on them towards the end of the baking time! For your next batch, try taking them out of the oven while they still have a hint of gooeyness in the center. Remember, they will continue to firm up as they cool. Additionally, ensure your oven temperature is accurate; an oven thermometer can help with that!
Are there any dietary considerations I should keep in mind?
Yes! These peanut butter blondies contain gluten and nuts. If you’re catering to those with dietary restrictions, you can use a gluten-free flour blend and substitute peanut butter with sunflower seed butter for a nut-free option. Always check ingredient labels if there are allergies involved, and consider making a flax egg for a vegan choice!
Can I use different types of sugars in my blondies?
Definitely! While light brown sugar is recommended for its moisture and deep flavor, you can also use dark brown sugar for a richer taste. If you’re looking for a healthier alternative, coconut sugar can also be a great substitute. Just keep in mind that each sugar brings its own unique sweetness profile, so feel free to experiment!
