Ingredients
These peanut butter blondies are soft and chewy with a delicious peanut butter flavor and tons of Reese’s Pieces and chocolate chips. A quick, easy, one-bowl, no mixer recipe.
For the Blondie Base
- 2/3 cup unsalted butter (170 grams)
- 3/4 cup peanut butter (about 270 grams)
- 2 cups light brown sugar (420 grams)
- 2 teaspoons vanilla
- 3 large eggs
- 2 cups all-purpose flour (250 grams)
- 1/4 teaspoon salt
Add-ins
- 3/4 cup Reese’s Pieces (about 140 grams)
- 3/4 cup chocolate chips (about 120 grams)
How to Make Peanut Butter Blondies
Step 1: Preheat the Oven
Preheat the oven to 350F (180C) degrees.
Step 2: Prepare the Baking Pan
Line a 9×13 inch pan with parchment paper, leaving an overhang over the sides for easy removal later. Alternatively, lightly grease the pan.
Step 3: Melt the Butter and Peanut Butter
In a large microwave-safe bowl, melt together the unsalted butter and peanut butter. Stir until smooth when almost melted.
Step 4: Mix in Sugar and Eggs
Whisk the light brown sugar into the peanut butter mixture. Then whisk in the eggs and vanilla extract until there are no visible pieces of egg.
Step 5: Combine Dry Ingredients
Gently fold in the all-purpose flour and salt into the mixture. Stop mixing once there are no streaks or lumps of flour visible.
Step 6: Add Chocolate Chips & Candies
Fold in the Reese’s Pieces and chocolate chips until evenly distributed throughout the batter.
Step 7: Pour Batter into Pan
Spoon or pour the batter into the prepared pan, spreading it smoothly on top.
Step 8: Bake
Bake in the preheated oven for about 30 minutes. Check if the top looks set; an inserted toothpick should come out clean or with a few damp crumbs. If you prefer less gooeyness, bake for up to 35 minutes.
Step 9: Cool and Slice
Allow the bars to cool in the pan. When ready to slice, lift them out using parchment overhang (if used). Place on a cutting board and slice with a thin knife for best results. For optimal slicing without melting too much chocolate, let cool for about 2½ hours before cutting.
How to Serve Peanut Butter Blondies
Serving peanut butter blondies can elevate your dessert experience. They are delicious on their own, but pairing them with complementary items can enhance their flavors and textures.
With Ice Cream
- Vanilla Ice Cream: The classic combination of warm blondies with creamy vanilla ice cream creates a delightful contrast in temperature and flavor.
- Chocolate Ice Cream: For chocolate lovers, pairing with rich chocolate ice cream adds an extra layer of indulgence.
With Fresh Fruit
- Sliced Bananas: The sweetness of fresh bananas balances the richness of the blondies, making for a refreshing treat.
- Berries: Strawberries or raspberries add a tartness that cuts through the sweetness of the blondies.
With Whipped Topping
- Homemade Whipped Cream: Light and airy whipped cream complements the chewy texture of the blondies perfectly.
- Chocolate Whipped Cream: For an extra chocolatey kick, use chocolate-flavored whipped cream to enhance the dessert experience.
With Nut Toppings
- Chopped Peanuts: Adding chopped peanuts gives a crunchy texture that contrasts nicely with the soft blondies.
- Candied Pecans: Sweet and crunchy pecans can add a delightful twist to every bite.
How to Perfect Peanut Butter Blondies
To achieve the best peanut butter blondies, consider these simple yet effective tips.
- Use Room Temperature Ingredients: This helps to create a smooth batter and ensures even mixing.
- Don’t Overmix the Batter: Mix just until combined; overmixing can lead to dense blondies instead of soft and chewy ones.
- Use Quality Peanut Butter: Opt for a good-quality peanut butter for optimal flavor. Creamy varieties work best for this recipe.
- Experiment with Mix-ins: Feel free to add other ingredients like chopped nuts or different types of chocolate chips for variety.
- Check for Doneness: Keep an eye on baking time; slight gooeyness is ideal, but be careful not to under-bake too much.
- Cool Before Slicing: Allowing your blondies to cool completely makes slicing easier and results in cleaner edges.
Best Side Dishes for Peanut Butter Blondies
Pairing side dishes with peanut butter blondies can create a well-rounded dessert experience. Here are some great options:
- Fresh Fruit Salad: A mix of seasonal fruits adds freshness and balances the sweetness of the blondies.
- Chocolate Dipped Strawberries: These provide a luxurious touch that complements the flavors in the blondies beautifully.
- Nutty Granola: A small serving of granola adds crunch and enhances nutty flavors while providing a fun textural contrast.
- Caramel Sauce Dip: Drizzling caramel sauce over each slice creates an indulgent experience for those who love rich flavors.
- Yogurt Parfait: Layer yogurt with berries for a refreshing side that balances sweetness while adding creaminess.
- Coffee or Tea Pairing: A hot cup of coffee or tea offers a warm beverage option that pairs well with sweet desserts like these blondies.
Common Mistakes to Avoid
When baking peanut butter blondies, it’s easy to make small errors that can lead to disappointing results. Here are some common mistakes and how to avoid them.
- Incorrect oven temperature: Always preheat your oven to 350°F (180°C). An uncalibrated oven can lead to undercooked or overcooked blondies.
- Not measuring ingredients accurately: Use a kitchen scale or proper measuring cups for precise measurements. This ensures the right texture and flavor.
- Overmixing the batter: Mix until just combined. Overmixing can result in tough blondies instead of soft and chewy ones.
- Using old ingredients: Fresh ingredients matter! Check that your baking soda, flour, and peanut butter are fresh for the best taste.
- Skipping parchment paper or grease: Always line your pan with parchment paper or grease it well. This prevents sticking and makes removal easy.
