Stepwise Method: Peanut Butter Blondies

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your Peanut Butter Blondies bake evenly.
Step 2: Prepare the Baking Dish
Grease your 9×13-inch baking dish with a bit of butter or line it with parchment paper for easy removal later.
Step 3: Cream Butter and Peanut Butter
In a large mixing bowl, combine the softened salted butter and creamy peanut butter. Using a spatula or electric mixer, cream the two together until they are smooth and well combined.
Step 4: Add the Sugars
Add the packed brown sugar and granulated sugar to the butter mixture. Mix until fully incorporated and fluffy.
Step 5: Incorporate the Eggs and Vanilla
Crack in the three eggs, one at a time, mixing well after each addition. Then, add the vanilla extract and blend until the mixture is smooth and creamy.
Step 6: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add this dry mixture into the wet ingredients, stirring gently until just combined. Be careful not to overmix.
Step 7: Fold in Peanut Butter Chips
Gently fold in the peanut butter chips until evenly distributed throughout the batter.
Step 8: Bake
Pour the batter into your prepared baking dish, spreading it evenly. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Step 9: Cool and Serve
Once baked, remove the blondies from the oven and let them cool in the pan for about 10-15 minutes. Then, transfer to a wire rack to cool completely. Cut into squares and enjoy your delectable Peanut Butter Blondies!

- Whole Wheat Flour: Substitute half of the all-purpose flour with whole wheat flour for added fiber.
- Reduced Sugar: Decrease the amount of granulated sugar or use a sugar substitute to cut back on sweetness.
- Applesauce: Replace one egg with ¼ cup of unsweetened applesauce for a lower-calorie option.
