Step by Step Instructions
Here is how to make the raspberry white chocolate blondies. For the full ingredient list and instructions, see the recipe card below. You will need an 8x8-inch square cake pan, a small saucepan, a blender, and a fine mesh sieve.
Make the Raspberry Sauce
Step 1: In a small saucepan, add the raspberries, sugar and water. Heat over medium-low heat for 5 minutes, stirring occasionally.
Step 2: Transfer raspberry mixture to a blender. Puree the mixture until smooth.
Step 3: Pour mixture back into the saucepan through a fine mesh sieve. Using a whisk, stir the pureed raspberry mixture through, leaving the solids in the sieve to be discarded.
Step 4: Cook mixture over medium heat for 10 minutes or until thickened. Set aside to cool slightly.
Make the Blondies
Step 1: Heat oven to 350°F. Line an 8x8-inch cake pan with a 6-inch strip of parchment paper and a light coating of cooking spray on the bottom and sides of the pan.
Step 2: In a medium bowl, add the butter, brown sugar, egg, egg yolk, and vanilla. Stir with a whisk until fully combined.
Step 3: Add the dry ingredients (flour, baking powder and salt.) Fold butter mixture and flour mixture together using a rubber spatula just until combined and you no longer see the flour.
Step 4: Using a rubber spatula, fold in the chopped white chocolate.
Step 5: Transfer mixture to the prepared pan. Using an offset spatula, spread batter in an even layer making sure to push it to the edges and corners.
Step 6: Drop the raspberry sauce in tablespoonfuls all over the top of the batter. Using a knife, drag it through the batter and raspberry sauce to create swirls in the top, making sure to go all the way to the edges.
Step 7: Place pan in the oven and bake for 25-27 minutes or until the edges are just beginning to brown.
Step 8: Remove from oven and let cool completely in pan, at least 1 hour.
Step 9: Using the parchment paper, pull the blondies out of the pan and place on a cutting board. Cut into squares or your desired size.
- You can use lemon juice in place of the water in the raspberry sauce to add a bit of tartness.
- To save time, you could melt raspberry jam in a saucepan instead of making the raspberry sauce. I would use drizzle and swirl about ½ cup of melted raspberry jam on top.
- When you put hot stuff into the blender, be sure to leave the top off a crack to allow steam to escape. Simply put a kitchen towel over the crack before blending to prevent any messes.
- To get perfectly smooth cuts, allow bars to cool on the counter and then place in the refrigerator for 20 minutes before cutting.
- You do not want to overcook blondies or they will come out cakey. Be sure to take them out when the edges are beginning to brown and are beginning pull away from the pan for best results.
- For a variation, use 1 ½ teaspoons almond extract in place of the vanilla. You can even top with sliced almonds before baking!
You bet! frozen raspberries will work just as good as fresh for the raspberry sauce.
Yes. White chocolate chips would be great too! Add 1 cup of white chocolate chips in place of the chocolate bar.
Sure! The recipe can be doubled and baked in a 9x13-inch cake pan.

Raspberry and white chocolate blondies can be stored at room temperature in an airtight container for up to 3 days or in the refrigerator for up to a week.
