Ingredients you’ll need

Here’s a list of ingredients you’ll need to make these brownies. You can find my recipe card at the bottom of this post for the complete list with their amounts.

Unsalted butter
Granulated sugar
Cocoa powder: I use and love Dr. Oetker Fine Dark Cocoa Powder.
Salt
Large eggs: You’ll need 2, cold, straight from the fridge.
Vanilla extract
Plain/all-purpose flour: You only need 1/2 cup (60g) of flour. Using a small amount of flour is what makes for extra fudgy brownies.
Chocolate chips: You can use milk, dark, or semi-sweet.
KitKat bars: You’ll need 16 2-finger bars, or 8 4-finger bars.

How to make Fudgy KitKat Brownies

To make these KitKat brownies, simply start by placing the butter, sugar, cocoa powder, and salt into a microwave-safe bowl, and heating for 1 minute.

Stir well, then microwave for another minute. The mixture should very warm/hot to the touch.

Add the eggs and vanilla, and mix well until combined.

Fold in the flour until fully combined, then gently fold in the chocolate chips, making sure not to let them all melt into the very warm batter.

Spoon half of the batter into an 8×8-inch square baking pan lined with foil or parchment paper.

Place the whole KitKat bars on top, then spoon the rest of the batter over the KitKats, and spread out evenly.

Sprinkle with the crushed KitKat bars.

Bake for 35 – 40 minutes, or until the centre is no longer jiggly and a toothpick inserted comes out almost clean.

Allow to cool completely in the pan on a wire rack before cutting into bars.

The printable recipe card with the full list of ingredients, their measurements, and instructions can be found at the bottom of this post.

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 Brownies are:

super quick and easy to make
incredibly thick and fudgy

How long will these brownies last? These brownies will stay fresh, stored in an airtight container, at room temperature or in the fridge for up to 1 week.

Can I freeze these KitKat brownies? Yep. They also freeze well for up to 3 months. Thaw overnight in the fridge before serving. If desired, allow to come to room temperature.
