In a medium-sized saucepan, melt the butter and the white chocolate chips over medium heat. Stir with a spatula or a whisk to incorporate the butter and chocolate into one, smooth mixture.
Once the butter and white chocolate chips have melted and incorporated, take the saucepan off the heat. Let the mixture cool for 5 minutes.
The white chocolate and butter may separate as the mixture cools, and that's ok. Just whisk them back together.
Prepare the chocolate chips
While the butter/white chocolate mixture cools, prepare the chocolate chips.
Add the chocolate chips and 1 Tbsp flour to a small mixing bowl. With a spoon or your hands, mix them together until the flour coats the chocolate chips. This will help keep the chocolate chips from sinking to the bottom of the blondies during baking.
Set the chocolate chips aside for now.
Add the vanilla extract, sugar, and eggs
Now add the vanilla extract to the saucepan with the butter/white chocolate mixture, and whisk to combine.
Next add the eggs. Whisk until the eggs are fully incorporated. The mixture will be thick and very smooth.
Now add the sugar and brown sugar. Whisk until combined.
Add the flour, salt, and chocolate chips
Add the flour and salt to the saucepan, and whisk until just combined.
Now gently fold in the chocolate chips
Pour the batter into the ramekins
Preheat the oven to 350 degrees
Oil eight, six ounce ramekins very well. To make the ramekins easy to put in and take out of the oven, place them on a baking sheet. (That way you just have to slide the baking sheet in and out of the oven.)
Evenly distribute the blondie batter among the ramekins. Each ramekin will fill almost to the top with batter.
Bake the blondies
Bake the blondies at 350 degrees for 36-38 minutes. The tops of the blondies will be golden brown, and a toothpick inserted in the middle will come out mostly clean.
Serve and enjoy!
Serve these white chocolate blondies alone, or with fresh whipped cream.
