Preparation Steps

• Preheat oven to 350°F (175°C). Grease a 9x13-inch baking pan or line with parchment paper.
• In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
• Beat in the eggs one at a time, then stir in the vanilla extract.
• In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt.
• Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
• Stir in the chocolate chips.
• Spread the batter evenly into the prepared baking pan.
• Drop spoonfuls of raspberry jam over the batter and use a knife to gently swirl it into the chocolate mixture.
• Bake for 22–25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
• Allow to cool completely in the pan before cutting into 16 bars.
