Ingredients Overview for Peanut Butter Cup Stuffed Blondies
To whip up these delightful blondies, you’ll need a few simple ingredients. No fancy stuff here; these are all pantry staples!
- Unsalted Butter: The rich foundation that gives the blondies that lovely chewy texture.
- Brown Sugar: For sweetness and a hint of caramel flavor; don’t skip it!
- Granulated Sugar: Balances the flavors and gives that delicious softness.
- Eggs: They bind everything together; I use large eggs for the best results.
- Vanilla Extract: Just a splash brings out all the flavors.
- All-Purpose Flour: The main ingredient that gives structure; if you need gluten-free, a blend works great too!
- Baking Powder: To help the blondies rise a bit.
- Salt: Just a pinch enhances all the sweet flavors.
- Peanut Butter Cups: The star of the show! I prefer the mini ones for ease, but regulars work too.

Serving Suggestions
These peanut butter cup stuffed blondies are delicious on their own, but you can definitely dress them up a bit. Try warming them up in the microwave just for a few seconds, then serve with a scoop of vanilla ice cream on top if you’re feeling indulgent. Drizzling a bit of chocolate sauce or extra peanut butter on top is another delightful option. Trust me, they are sure to impress your friends or family!

Tips for the Perfect Peanut Butter Cup Stuffed Blondies
- Don’t Overmix: This keeps your blondies soft and tender, which we definitely want!
- Experiment: Feel free to swap in different kinds of chocolate or nuts if you like; the world is your oyster!
- Storage: Keep them in an airtight container for up to a week (if they last that long!).
- Chill Before Cutting: If you find them too gooey, give them a bit of time in the fridge to firm up before slicing.
