Preheat your oven to 170°C and grease a 8x8 inch baking pan or line it with parchment paper for easy removal.
Melt the butter and white chocolate in the microwave.
In a mixing bowl, combine the eggs and sugar. Whisk until well incorporated.
Add in the vanilla extract and melted butter/chocolate and whisk.
Fold in the flour, mixing until the dry ingredients are fully incorporated into the wet mixture.
Pour the blondie batter into the prepared pan and spread it out evenly.
Equally distribute 16 Rolos into the batter, ensuring they are covered.
Place the remaining Rolos and a handful of chocolate chips on top of the batter.
Bake in the preheated oven forabout 35 minutes.
Allow your Rolo Blondies to cool in the pan for about 15 minutes, then use the parchment paper to lift them out of the pan and onto a wire rack to cool completely.
Once cooled, cut into squares and enjoy the gooey, caramel-filled bliss!
