Peanut Butter Blondies are the ultimate peanut butter treat for the serious peanut butter lovers in your life! If left unfrosted, these are baked goods that ship well and perfect to include in a care package for someone special!

These just so happen to be Gluten-Free Peanut Butter Blondies even, thanks to Bob's Red Mill Gluten-Free 1 to 1 Baking Flour! Although I made a batch with Bob's Red Mill's organic all-purpose flour just so I could compare and see if there was any difference. (Answer: None that I could tell!)

When I heard that Bob's Red Mill wanted to sponsor a post about creating a care package for someone special with delicious baked goods added to it, I immediately thought of my girls' birthmothers.

I've mentioned on here before that our family was built through adoption, and we have open relationships with both of our daughters' birthmothers, who are so special to us.

We try to stay in touch through Skype, texting, IG and the occasional visit or card, since we don't live close by. But sometimes, and definitely not frequently enough, I just want to do something a little extra.

I mean, who doesn't love receiving fun mail every now and then?!

I love that Bob's Red Mill believes that baking for others is one of the surest signs to show how much you care. I couldn't agree more.

My primary love language is service and baking for my family and friends is one of the ways I show that I love them! Plus, psychologists have found that baking for others makes the baker feel as good as the recipients!

So I decided September was the perfect time to send a back-to-school care package for my girls' birthmothers.

One of them is still in school and the other graduated last year, but I figured it would still be a fun theme because I could include first-day-of-school pics of our girls along with some fun supplies like post-its and sharpies - things I use on a daily basis and feel like I can never have enough of! Add in a few fun extras - a small fall-scented candle, a cute paperweight, and some freshly sharpened pencils (always reminds me of the most perfect and romantic quote from any movie ever - "I would send you a bouquet of newly-sharpened pencils if I knew your address." - Joe Fox, "You've Got Mail") - along with handmade cards and art from the girls and I felt pretty good about the care packages we put together.

The girls had fun helping too! Clara was especially pleased to be sending a card she made herself using flowers that she picked and pressed in the flower press she got for her 6th birthday this year. And of course, what's a care package without some yummy baked goodies added to it?

Bob's Red Mill sent me some of their products to use, including their organic all-purpose flour and their gluten-free 1 to1 baking flour, which was awesome since one of our daughter's birthmoms has a gluten sensitivity and lives a gluten-free lifestyle.

I had never tried Bob's Red Mill's gluten-free 1 to 1 baking flour before, but it is amazing. Seriously, who knew it was so easy to make basically anything gluten-free?!

I honestly couldn't tell a difference between the two batches of blondies, so it was a good thing that I used large Reese's Pieces on the gluten-free ones and mini Reese's Pieces on the others so I could tell them apart!

Quick Tips on Shipping Baked Goods

  1. Avoid shipping frosted or glazed baked goods, especially during the warmer months! You don't want the treats showing up melted, soggy or sticky, which is apt to happen when shipping things with frostings or glazes. It's why even though these peanut butter blondies can be made with a peanut butter frosting, I opted to leave that off for these care packages and simply sprinkle them with Reese's Pieces before baking instead. Here are some ideas of baked goods that ship best:
  2. Ship the same day you bake, but be sure to let the treats cool completely before packaging them up.
    • Priority mail typically takes only 2-3 days if mailed in the U.S., which is usually going to be okay for most of the baked goods that ship well anyway. I baked these peanut butter blondies on Wednesday morning, took them to the post office that afternoon, and was told they would be delivered on Friday using a flat-rate shipping box, which seems good to me!
  3. Pack baked goods in airtight containers or bags to keep them tasting fresh.
    • If you are packing multiple baked goods, like chocolate chip cookies and brownies, wrap them up individually. Don't ever pack them in the same container!
    • Use wax paper between layers to prevent sticking, especially if packing things like brownies or bars in a container rather than wrapping them up separately.
    • Consider buying disposable baking pans to bake the treats in and ship them in those.
    • Be sure to nestle everything securely by filling in any extra space with something like tissue paper to make sure they can't move or shift around when the package inevitably gets shaken.
  4. Provide extra cushioning around the container you are shipping the baked goods in.
    • You can use bubble wrap, newspaper, packing peanuts, or even just crumpled up tissue paper if there isn't a whole lot of extra space in your box.
    • In these care packages, I filled a small cardboard box with the individually wrapped peanut butter blondies to protect them, then used bubble wrap around the more fragile items like the scented candles and framed pictures. Finally, I filled in the remaining gaps with colorful tissue paper, which filled a duel role of keeping the care package items from shifting about inside while also adding some fun color!

Tips for keeping Peanut Butter Blondies Fudgy

Is it weird to talk about something with no chocolate in it in terms of having a fudgy center? Because these rich and delicious peanut butter blondies are definitely fudgy in the middle as long as you make sure not to overbake them.

If you bake them a little too long, welllll, they will still taste delicious (speaking from experience here - it's not like they are a total loss) but they might be closer in texture to a peanut butter cookie rather than a soft, fudgy blondie (basically a brownie with no chocolate but a brownie-like texture), which is kind of what we're going for here.

Along with making sure we don't overbake, there are three important ingredient components that ensure these peanut butter blondies are on the fudgy side.

  1. Melted butter
  2. An extra egg yolk
  3. No baking powder

Using melted butter instead of creaming the butter with the sugar is important here because it results in a denser, more brownie-like texture instead of a fluffier, more cake-like bar.

Also, just like with my favorite thick, fudgy, chewy ultimate brownies, I included an extra egg yolk which helps with a little bit of that extra richness and moisture that is the hallmark of a fudgy, chewy brownie (or blondie in this case).

The last ingredient trick to keeping these peanut butter blondies on the fudgy side is to actually leave out any leavening agent like baking powder, which helps keep these wonderful bars on the dense, chewier side.

These blondies are one of the best peanut butter desserts I have had in a long time and the girls went absolutely crazy over the frosted ones. I couldn't decide whether I preferred them frosted or unfrosted. It's such a toss-up!

  1. These look delicious! Love the tips-- I live too far away from my family to ship baked goods -- would take 2 weeks! That first shot with the peanut butter topping and the fork has my mouth watering!

  2. Wow, these look delicious! I need to make these! Everything looked great...until I saw the nutrition facts, lol! But that won't stop me. I would definitely have to send some to my brothers who are still in college. All three of them live in Provo. Thanks for the shipping tips! And what a sweet thing to do for the girls' birthmothers. You are so sweet and thoughtful, Amy!

    1. Lol - yeah, these definitely aren't doing my hips any favors! Although if you make them without the frosting that cuts down on the calories big time. 🙂

  3. What a beautiful care package you sent! I would be more than delighted to receive one 🙂 . And those peanut butter blondies look so decadent, yes, even without chocolate!

  4. These little delicious squares would go perfect with my latte this afternoon. Shipping baked goods can be a challenge. Last year I shipped cookies in boxes, and used lots of bubble wrap. Everything arrived fine.

  5. I love sending care packages with baked goods! My brother-in-law just started his freshman year at Columbia, so it looks like it's time to send him a taste of home.

  6. What a lovely story and great tips on packing baked goods! My daughter lives and works in Hanoi but sadly I don't think baked goods would make it through customs. I can always pack some in my suitcase the next time we visit. Thanks for sharing your great recipe Amy!

  7. These look AMAZING! Love the candies up on top. My kiddo would absolutely LOVE it if I made these - or better yet, if we made them together!

  8. 5 stars
    These look so, so good, Amy! I could definitely eat a few! The care package idea is so cute, I love it! It would be lovely to receive something like these blondies in the post!!

  9. 5 stars
    I'd certainly love to have a nice square of peanut butter blondie with my coffee. The frosting looks delicious. The M & M's remind me of Fall and Halloween. Whenever we mail cookies or snacks we do use plenty of bubble wrap.

  10. 5 stars
    Anything with peanut butter always makes me happy! Thanks for sharing the tips on shipping baked goods too.

  11. 5 stars
    I love this idea! And such great tips for packing up baked goods. I've got a nephew who is expecting a baby that would be happy to receive a gift of these goodies!

  12. Peanut butter blondies are YUMMY.......... Its look amazing .These blondies are one of the best peanut butter desserts. Girls went absolutely crazy over the frosted ones.

  13. How would you recommend storing these if they cannot be eaten that day? With the cream in the frosting I'm assuming they would need refrigeration.

  14. These peanut butter and chocolate blondies are a fantastically easy and delicious treat that your kids will love.
