Giant Chocolate Chip Peanut Butter Cookie – One giant cookie that is loaded with peanut butter flavour, and studded with chocolate chips. Perfect for when you don’t want to make a whole batch!
Giant Chocolate Chip Peanut Butter Cookie
You guys have been loving my Giant Chocolate Chip Cookie I shared with you a couple of years ago, so I thought I’d be kind enough and bring you another GIANT cookie recipe!
This Giant Chocolate Chip Peanut Butter Cookie is thick and chewy, loaded with peanut butter flavour, studded with chocolate chips, and is big enough to share between four people – or not, I won’t judge. 😉

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

- Large egg
- Smooth peanut butter
- Vanilla extract
- Plain/all-purpose flour

How to make Giant Chocolate Chip Peanut Butter Cookie
To make this giant peanut butter cookie, simply whisk together the melted butter and sugars. Add the beaten egg, peanut butter, and vanilla, and whisk until combined.
Add the flour (start with 1/4 cup), cornflour, baking powder, baking soda, and salt, and mix until combined. At this point, you’ll have a runny dough. Start adding more flour, 1 tablespoon at a time, until the dough is not longer runny. I needed 2 and 1/2 more tablespoons of flour, but you may need more or less. Fold in the chocolate chips.
Be careful not to add too much flour though, otherwise you’ll end up with a thick, cakey cookie – and who wants that??
Drop the dough onto a baking tray lined with parchment paper or silicone mat, and press some extra chocolate chips on top. Bake for 17 – 20 minutes until golden brown around the edges.
The centre of the cookie will still be a little under-baked, but it’s fine – it will firm up as it cools. Leave to cool on the tray until it is firm enough to be moved to a wire rack or plate.
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.
Can I use different add-ins in this cookie? Sure! Try adding chopped nuts along with the chocolate chips for added crunch. OR use crunchy peanut butter instead of smooth.
Can I freeze this giant cookie? Yes. Freeze whole or cut into quarters for up to 3 months. I highly recommend freezing the dough instead, so you can have a freshly-baked cookie whenever you want! The dough can be kept in the fridge for up to 5 days, or frozen for up to 3 months. Bake from frozen.
How long will this cookie last? This cookie will stay fresh, kept in an airtight container, at room temperature for up to 1 week.
