Ingredients you’ll need

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

For the cookie dough:

  • Plain/all-purpose flour
  • Baking powder
  • Baking soda
  • Salt
  • Unsalted butter
  • Light brown sugar
  • Caster/granulated sugar
  • Large egg
  • Vanilla extract
  • Chocolate chips

For the chocolate fudge centre:

  • Chocolate: You can use milk, dark, or semi-sweet.
  • Sweetened condensed milk

How to make Fudge Stuffed Chocolate Chip Cookie Bars

To make and assemble these cookie bars, simply make the cookie dough as instructed below. Press half of the cookie dough into an 8×8-inch square baking tray lined with foil or parchment paper.

For the fudge, melt the chocolate in the microwave, then stir in the sweetened condensed milk. Pour into the pan, on top of the cookie layer, and spread out evenly. Top with the remaining cookie dough.

Bake for 25 – 30 minutes until lightly golden brown. Allow to cool completely in the pan, then refrigerate for at least 2 hours before slicing into bars.

TIP: As soon as you’ve removed the pan from the oven, place it into the freezer for 2 hours. This will speed up the cooling time, and you’ll get neat, clean slices!

The printable recipe card with the FULL list of ingredients 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.
