Ingredients
1 1/2 cups packed light brown sugar
1/2 cup unsalted butter, melted
3/4 cup creamy peanut butter
2 large eggs
1 teaspoon vanilla extract
1 1/4 cups all-purpose flour
1 teaspoon baking powder
1 teaspoon salt
2 to 3 tablespoons jam or thick fruit preserves
2 tablespoons chopped honey roasted peanuts
Coarse sea salt for finishing
Directions
Preheat your oven to 350°F (175°C). Lightly grease an 8-inch square baking pan with butter or nonstick spray and set aside.
In a medium bowl, whisk together the flour, baking powder, and salt until well combined. Set the dry mixture aside.
In a large bowl, whisk together the brown sugar, melted butter, and peanut butter until well blended. Add the eggs one at a time, whisking well after each addition. Stir in the vanilla extract until incorporated.
Gently fold the dry ingredients into the wet ingredients, stirring just until combined and no streaks of flour remain. Do not overmix.
Pour the batter into the prepared pan and smooth the top into an even layer. Dollop the jam evenly over the surface and use a butter knife to swirl it gently into the batter, creating a marble effect.
Sprinkle the chopped roasted peanuts evenly over the top of the batter.
Bake for 35 to 40 minutes, until a toothpick or cake tester inserted into the center comes out clean or with just a few moist crumbs. Do not overbake.
Remove the pan from the oven and immediately sprinkle the coarse sea salt over the warm blondies. Allow the bars to cool completely in the pan, then cut into 16 squares and serve.
Comments
Every ingredient is a pantry staple or bulk-bin item at every Charlotte chain—peanut butter, jam, and roasted peanuts are cheaper at ALDI or Walmart, and sea salt is common everywhere. At roughly $0.80 to $1.00 per serving (brown sugar, butter, and peanuts are the cost drivers, but modest quantities), this hits a comfortable weeknight dessert price. The stated 60 minutes is honest for mixing and baking, though you'll want to cool for 15 minutes before cutting into squares. It's a forgiving, no-attention bar that reheats well and makes 16 servings, perfect for a family dessert or lunchbox addition, and the salty-sweet profile is a genuine crowd-pleaser with no fussy technique.
