Peanut Butter Mars Bar Cookies




Another peanut butter recipe here, but in my opinion there can never be too many.
These cookies are melt in your mouth amazing, with a gooey mars bar treat hidden inside, for me they're near perfect.

The plain peanut butter cookie dough also works really well just baked on its own or you can swap the mars bar centre out for any chocolate bar you fancy, or just add a handful of chocolate chip into the mix! Swap and change however ya like to make your perfect cookie.

They couldn't be more quick or easy to make and only take about 10 minutes to bake so you'll be enjoying them in no time!


You will need:
125g salted butter, softened to room temperature
100g dark brown sugar
50g granulated sugar
1 egg
125g creamy peanut butter
1 tsp vanilla extract
1/2 tsp baking soda
175g plain flour
Mars bars (approx 3, chopped) or mini mars bars will do
Makes 12-24, depending on size

  • Preheat oven to 180°C and grease two cookie sheets.
  • In a large bowl using a hand-held mixer or using a stand alone mixer, cream the butter and sugars together. 
  • Mix in the peanut butter, egg, and vanilla. 
  • Gradually mix in the baking soda and flour using a wooden spoon. 

  • Chill the dough for 30 minutes in the fridge as it helps it to become more manageable.
  • Take a spoonful of the chilled dough. Press this down onto the cookie sheet and pop a piece of Mars bar in the middle, cover with another spoonful of the dough and seal down the sides. Repeat with the rest of the dough. Make sure to leave a good space between the dough balls on the sheet as they do spread quite a bit!



  • Bake for 9-12 minutes, or until they're golden brown.
  • Remove from oven and allow to cool on a wire rack. 


As you can see the cookies I've made are quite large, I used about a tablespoon for the base of each and quite a good chunk of Mars bar for the centre. You can use smaller pieces of Mars in the centre if you want a smaller cookie, or obviously if you want them bigger, go bigger!

Now it's again the time to enjoy the fruits of your labour… that is, if you're not too full from munching on Mars pieces as I usually am.
