Peanut Butter Pumpkin Brownies

Making a batch of brownies is such an easy thing to do – and even easier when you use a box mix. But how about we elevate those brownies for the autumn with some canned pumpkin, and for good measure add a layer of peanut butter cookie dough?

Then, if that isn’t quite enough, throw on some Reese’s Pieces with their autumnal orange and yellow colors, and some almond toffee pieces too! This batch of brownies is a decadent and easy dessert and you need to make them ASAP!

Peanut Butter Pumpkin Brownies Ingredients

Ingredients used in this recipe

For my UK readers: When I go on vacation to the USA, I like stock up on my favourite American food products and ingredients, so you’ll find them used in some of the recipes on The Purple Pumpkin Blog. However, we can buy a lot of American ingredients online these days, and in supermarkets (check the World Foods aisle!) which is awesome! (Although sometimes the price can be on the high side…) When I use American ingredients in recipes that I share on my blog, I always aim to suggest British alternatives or include Amazon affiliate links to where you can buy them online.

  • Betty Crocker Fudge Brownie Mix – or any brand you like – or your own brownie recipe if you prefer. In this recipe we’ll be combining with oil, water and canned pumpkin (leave out the eggs if required on box instructions).
  • Betty Crocker Peanut Butter Cookie Mix – plus ingredients to make (oil, eggs, water). This cookie mix is not available in UK supermarkets (that I’ve found) which is super annoying as we stock other Betty Crocker products here. However, the dough is pretty easy to make, or I reckon you could add some peanut butter or even crushed peanuts to a regular cookie mix and you’ll still get the peanut flavour. Or buy some ready-made cookie dough and fold in some chopped up peanuts.
  • Canned Pumpkin – can find in UK supermarkets these days!
  • Reese’s Pieces – we sell those here right?
  • Hershey’s Heath Toffee Bits – but we don’t sell these. You could buy a Daim Bar (Didn’t they used to be called Dime Bars?) as they’re very similar to the American Heath toffee bits. Just crush the Daim into small pieces. You could also use regular toffee pieces (find in the cake ingredients aisle).

Equipment used in this recipe

This recipe uses American cup measurements. Since I use this type of measurement often, I find it handy to have a set of measuring cups in the kitchen.

The brownies are baked in a (23cm x 33cm) 9″ x 13″ baking pan and you’ll need the usual mixing bowls and spoons to prepare the ingredients.

These brownies are so easy to make it’s ridiculous! Dump the brownie mix into a bowl with oil, water, and canned pumpkin and mix until combined and pour into a greased baking dish and spread out evenly.

Make up the cookie mix according to the package instructions. Press out the cookie dough on top of the brownie mix – using your hands is the easiest way to do it.

  • 1 box brownie mix
  • ½ can of 100% pure pumpkin
  • ⅔ Cup Vegetable Oil
  • ¼ Cup Water
  • 1 package peanut butter cookie mix (plus eggs, water, and oil to make cookies according to package)
  • ½ cup Hershey's Heath Milk Chocolate Toffee Baking Bits

  2. Place brownie mix in a bowl with pumpkin, oil and water and stir until well combined.
  3. Add brownie batter to the pan and spread evenly.
  4. Make the peanut butter cookie dough according to package instructions.
  5. With your hands, press out cookie dough and lay over the brownie layer until you have used all of the cookie dough (It will create a few gaps and that is okay).

  7. Bake for 40-45 minutes. Check brownie is cooked through by inserting a cocktail stick into the middle - it will come out clean when done.
