Happy June, friends!
Summer is here, and while everyone else is posting frozen desserts and summer recipes, I’m here posting a Peanut Butter Cup Blondies recipe instead!
You love my unexpected logic, right? π
We’ve been having beautiful summer weather here in the UK. But instead of being outdoors and celebrating the wonderful weather, I’ve been stuck in bed all weekend ill!
Not only that too, yesterday was the giant man-baby and I’s 6th anniversary of dating too. Celebrated in bed! And not the way you’re thinking too! (Get your mind out the gutter, ha!)
There’s just something about celebrating your anniversary in front of a sick bowl, eh?
At least you don’t have to go out to fancy restaurants or do anything special to celebrate these Reese’s Peanut Butter Blondies though. They’re a celebration in themselves!
Perhaps they should be called Double Peanut Butter Blondies as they’re not just made with Reese’s Peanut Butter Cups, they also have smooth peanut butter in the blondies batter too.
And did I mention chocolate chips too? You can’t beat peanut butter and chocolate in my opinion, but you could easily switch up the chocolate chips to peanut butter chips and a generous drizzle with chocolate on top, too!

These Reese's Peanut Butter Cup Blondies taste phenomenal and are made with both peanut butter cups and peanut butter, and studded with chocolate chips throughout.
Ingredients:
- 125g (1 cup) plain (all-purpose) flour
- ½ tsp baking powder
- ½ tsp salt
- 55g (¼ cup) unsalted butter, softened
- 65g (¼ cup) smooth peanut butter
- 200g (1 cup, packed) light brown sugar
- 1 tbsp vanilla extract
- 1 large egg
- 65g (β cup) dark chocolate chips
- 6 Reese's peanut butter cups, coarsely chopped
Directions:
- Preheat the oven to 180°C/350°F, and line an 8x8-inch pan with parchment paper allowing an overhang for ease of removal. Set aside.
- Sift or whisk together the flour, baking powder, and salt into a large bowl. Set aside.
- In a large mixing bowl, beat the butter, peanut butter, sugar and vanilla together until pale, then beat in the egg until well combined.
- Fold in the flour mixture until just combined, then stir through the chocolate chips and peanut butter cups.
- Transfer the mixture to the prepared pan and bake for 19 minutes, or until a toothpick inserted comes out with clean (some crumbs clinging is fine.)
- Remove pan from oven and allow to cool in the pan completely on a wire rack before cutting into 16 squares.

mmmm chewy peanut buttery goodness!!!!
Oh, what a sad way to celebrate an anniversary! At least you had some delicious blondies to make it all better. π These look delicious!!
hi plan to make these. do i need to butter the parchment paper when i put it in the pan?
Hi Dee. No, you don’t need to as parchment is non-stick. However, you can spray the pan with cooking spray and then add the parchment if you find that the parchment is sliding around in your pan.
Or if you prefer, you can grease and flour the tin if you prefer not to use parchment paper. Hope that helps.
