How to make Fudgy KitKat Blondies
Here’s a list of ingredients you’ll need to make these blondies. You can find my recipe card at the bottom of this post for the complete list with their amounts.
- Unsalted butter
- Light brown sugar: Using all brown sugar makes for extra fudgy blondies that have a rich caramelized flavour.
- Large egg + an egg yolk: An extra egg yolk makes for more chewier, fudgy blondies.
- Vanilla extract
- Plain/all-purpose flour
- KitKats: You’ll need 16 2-finger KitKat bars, or 8 4-finger bars.
To make these blondies, simply start by whisking together the butter and sugar until combined. Add the egg, egg yolk, and vanilla, and whisk until smooth and combined.
Add the flour and salt, and whisk until completely combined.
Spoon half of the batter into an 8×8-inch square baking pan lined with parchment paper. Place the whole KitKat bars on top, then spoon the remaining batter over the KitKats, spreading out evenly. Sprinkle with crushed KitKat bars.
Bake for 35 – 40 minutes, or until the edges are browned and the centre is no longer jiggly – just set.
Allow to cool completely in the pan on a wire rack before cutting into squares.

NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements.
Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.
These Fudgy KitKat Blondies are:
- super quick and easy to throw together
- deliciously chewy and fudgy
- infused with vanilla and have a deep caramelized flavour
- LOADED with whole KitKat bars
