Recipe Overview

Prep Time: 15 minutes | Cook Time: 25 minutes | Total Time: 40 minutes | Servings: 12

Ingredients

  • 1 cup unsalted butter (softened)
  • 1 cup granulated sugar
  • 1 cup packed brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 3/4 cups all-purpose flour
  • 1/2 teaspoon salt
  • 1/2 cup peanut butter (smooth or crunchy, depending on preference)
  • 1/2 cup jelly or jam (strawberry, grape, or blueberry work well)
  • Optional: 1/4 cup chopped peanuts or chocolate chips for extra texture.

Preparation Steps

Step 1: Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper. This ensures easy removal and prevents sticking.

Step 2: In a large bowl, cream the butter, granulated sugar, and brown sugar until light and fluffy. This step is crucial for a tender texture. Tip: Use a stand mixer for efficiency.

Step 3: Beat in the eggs one at a time, then stir in the vanilla extract. Avoid overmixing to prevent a dense result.

Step 4: Gradually add the flour and salt, mixing until just combined. Common mistake: Overmixing at this stage can lead to tough blondies.

Step 5: Spread half the batter into the prepared pan. Dollop the peanut butter on top and swirl it gently with a knife for a marbled effect.

Step 6: Spread the jelly over the peanut butter layer, then cover with the remaining batter. Fun fact: The jelly adds moisture and a burst of flavor, balancing the richness of the peanut butter.

Step 7: Bake for 25 minutes or until the edges are golden and a toothpick inserted in the center comes out with a few moist crumbs. Tip: Avoid overbaking to maintain a fudgy center.

Step 8: Let cool completely before cutting into squares. Pro tip: Chill in the fridge for 1 hour to make slicing easier.

Cooking Tips

Best Results: Use room-temperature butter for smoother creaming. For a richer flavor, substitute 1/3 cup of the brown sugar with a caramel drizzle. Time-saving hack: Prepare the batter the night before and refrigerate, then bake fresh in the morning.

Flavor Variations: Swap the jelly for a fruit compote or add a swirl of chocolate sauce. For a nutty twist, mix in 1/4 cup chopped nuts or a drizzle of honey.

Ingredient Alternatives: Replace all-purpose flour with almond flour for a gluten-free option. Use natural peanut butter for a healthier base, or try a vegan butter substitute for a dairy-free version.
