Ingredients & What They Do

• Creamy peanut butter - This is the star of the show. It adds rich flavor, moisture, and that classic peanut butter taste. Using a regular creamy peanut butter (like Jif or Skippy) works best - natural peanut butter can separate and affect the texture.
• Butter - Softened butter brings flavor and helps create that chewy, tender blondie texture. It also helps the bars bake up with a rich, buttery base that balances the sweetness.
• Brown sugar + white sugar - Brown sugar adds moisture and a hint of caramel flavor, while white sugar keeps the bars from being too heavy. The combination gives just the right sweetness and chew.
• Eggs - These bind everything together and help give the blondies structure. They also contribute to the soft, rich texture.
• Vanilla extract - A little vanilla brings warmth and depth, enhancing all the other flavors without overpowering.
• All-purpose flour - Just the right amount of flour gives the blondies structure without making them cakey. It's what helps them hold together while still being soft and dense.
• Baking powder - Adds a bit of lift so the bars don't bake up too flat. It also helps keep them soft rather than overly dense.
• Milk - The milk adds just enough liquid to smooth out the batter and keep it moist. It also helps the flour blend in evenly.
• White chocolate chips - These melt into little pockets of creamy sweetness and pair perfectly with the peanut butter. You can swap in peanut butter chips or a mix of both if you want to double up on flavor.
• Icing drizzle (powdered sugar, peanut butter, milk) - This simple topping adds a sweet, creamy finish and makes these peanut butter and white chocolate blondies look bakery-style without much extra effort.

Step-by-Step Instructions

• 1. Preheat your oven to 350°F.
  • You want your oven fully heated before the blondies go in, so they bake evenly.
• 2. Grease a 9x13" pan or line it with parchment paper. (I prefer aluminum pans for baking bars and cakes.)
  • Either works! Parchment makes it easy to lift the bars out later, but greasing the pan works just fine too.
• 3. In a large mixing bowl, cream the peanut butter, softened butter, brown sugar, and white sugar. (I use my Kitchen-Aid mixer to do the mixing.)
  • Mix until it looks smooth and creamy. This step helps the sugars dissolve and gives your blondies that soft, chewy texture.
• 4. Add the eggs and vanilla.
  • Mix them in well so everything is evenly combined.
• 5. In a separate bowl, stir together the flour, baking powder, and salt.
  • This keeps the baking powder from clumping and helps it mix in evenly.
• 6. Add the flour mixture to the wet ingredients, alternating with the milk.
  • Start with a little flour, then a splash of milk, and repeat until it's all mixed in. Don't overmix - just stir until it's combined.
• 7. Gently stir in the white chocolate chips.
  • You can use a spatula or spoon for this step. Fold them in so they're spread throughout the batter.
• 8. Spread the batter evenly into your prepared pan.
  • It's thick, so take your time spreading it out to the corners. A rubber spatula works well.
• 9. Bake for 30-40 minutes.
  • Check with a toothpick - if it comes out with just a few moist crumbs, they're done. If it's still wet in the center, give it a few more minutes. Don't overbake or they'll dry out.
• 10. While they're cooling, make the drizzle.
  • In a small bowl, whisk together the powdered sugar, peanut butter, and milk until smooth.
• 11. Drizzle over the warm blondies.
  • Let the peanut butter brownies/blondies cool for about 10 minutes, then drizzle the icing on top. (Tip: Put the icing in a zip-top bag, snip the corner, and squeeze - it makes drizzling easy and neat.)
• 12. Let cool completely, then cut into squares.
  • Once they're cool, slice and enjoy! (I like my mini spatulas for serving bars.) Store in an airtight container for a few days, or freeze for later.

Tips for Success

• Use regular peanut butter, not natural - Natural peanut butter can separate and change the texture. A standard creamy peanut butter (like Jif or Skippy) gives the best results.
• Soften your butter, but don't melt it - Softened butter mixes better with the sugars. If it's too cold, it won't cream properly - if it's melted, the blondies can turn greasy.
• Don't overmix the batter - Once you add the flour and milk, mix just until everything comes together. Overmixing can make the blondies tough.
• Check doneness early - Ovens vary, so start checking around 30 minutes. The top should look set and a toothpick in the center should come out with moist crumbs - not wet batter.
• Let them cool before cutting - These blondies need time to set up. If you cut them while they're too warm, they may fall apart. Letting them cool also helps the icing set nicely.
• Customize if you like - Swap the white chocolate chips for peanut butter chips or dark chocolate chips, add chopped nuts, or even a sprinkle of flaky salt on top to balance the sweetness.
