peanut butter & jelly crumb cake

PB & J Crumb Cake 6

It's back to school for a lot of my neighbors, clients, friends, and even hubby is back to school this coming week. Another year of grad school; let's just throw another $15K to the ever-growing pile of debt shall we? Seems like we'll be paying student loans for the rest of our lives: mine and his. And now we're buying our first home...are we crazy? No, we're just like every other person on this planet living and breathing debt.

PB & J Crumb Cake 7
To me the beginning of back to school means peanut butter and jelly. I can't remember the last time I had crumb cake, but I wanted to experiment and make a PB & J crumb cake for the longest time. It came out pretty good. It's really rich, a lot of that has to do with the thick peanut buttery crumb topping. I would love to hear from you on what meals remind you of Fall and what are you excited to bake/cook/experiment with this coming Fall season?
PB & J Crumb Cake 3

peanut butter & jelly crumb cake
print recipe

1 3/4 cups all purpose flour
1/2 cup brown sugar
1/2 cup sugar
1/2 tsp ground cinnamon
1 tsp baking powder
1/2 tsp baking soda
1/2 tsp salt
1/2 cup butter, room temperature
3/4 cup buttermilk
1 large egg
1 cup crunchy peanut butter, room temp. (not natural)

for jam drizzle:
1 jar of strawberry or raspberry jam/jelly (I used raspberry: seedless)
Confectioners’ sugar for decoration (optional)

Preheat oven to 350F. Lightly grease and flour an 8x8 square baking pan.
In a large bowl mix the flour, brown sugar, sugar, cinnamon, baking powder, baking soda and salt.
Using a mixer (or by hand), beat in the softened butter until mixture resembles wet sand. No large lumps. If using a mixer, do not over beat. Remove between ¾ - 1 cup of the mixture to a medium bowl and set aside. (I did about a cup since I wanted a lot of crumb topping and thin cake; just like a crumb cake).
With the remaining mixture add in the buttermilk and egg, mix well. Then pour into the greased pan, spreading evenly. There is not a lot of batter; it does rise when baking so don’t worry. Take the remaining flour mixture that was set aside and add the cup of peanut butter to it.  Mix until you have a nice, almost dry crumbly mix.
Then drop or crumble large chunks of this onto the cake. Do not press the crumbs into the batter; just let them sit on top.
Bake for about 30 -35 minutes, until a tester inserted into the center of the cake comes out clean. While cake bakes make the jelly reduction. Take a small jar of strawberry or raspberry jam/jelly, and let gently melt in saucepan over low heat. Do not boil. To make the reduction slightly thicker add a bit of cornstarch (a TB or so). But you shouldn’t need to do this as after it’s melted it does thicken a bit.
When slightly cooled drizzle cake with the melted jam. Then dust with confectioners’ sugar if desired. Cool on a wire rack before slicing.


  1. Back to school for me, this coming Tuesday - eek!! I'm excited, but nervous. I wish I had some of that PBJ crumb cake to savor! :0)

  2. OMG i want some of this now!! yummmy

  3. For me the fall is all about chestnuts! Your crumb cake looks delicious and with such apropriate flavours for "back-to-school", just like the sandwiches kids take for lunch!

  4. I am with you, I love fall! I am a little sick of the 100 degree heat so I could use a little fall weather. I bet my kids would love this in their lunch than the usual pb&j sandwiches.

  5. Fall??? Whats that? We dont have fall here in Tampa! Sucks! I dont get to open my windows until around December!
    Apple pie had fall written all over it for me!
    Will your excuse me...I have a call on the BIMBO line!LOL LOL
    Gald you liked the video! I had to do multiple takes because I was laughing so hard..Now you know your a dork when you are the only one home and you are cracking up!!Yep thats me!!!

  6. I lived in Maryland for five years when I was young and we had the most beautiful falls! I totally miss them being in southern California when fall is usually the hottest time of the year! Hopefully it won't be too hot this fall and I can bake more, but I am also looking forward to lots and lots of butternut squash :)

  7. I would do anything to leave Califonia and live in New England, at least for the fall!

    This crumb cake is an awesome way to start getting ready for the season.

  8. Hi Dawn,
    I am so glad I found your blog! You and I think a lot alike, we LOVE food! This PB and J crumb cake is sooooo going on my list to make! Have a great weekend!

  9. My son, a big pb&j fan, would love these! Great blog!

    Thanks so much for the kind words on my blog.

  10. I love PB&J! I would love a piece of this now...with a glass of milk!

  11. you knew it was coming...

    it's peanut butter jelly time! :)

    fantastic bars. and may i say, i never want to go to school again. ever. :)

  12. These really look terrific... and I can't wait to start making lots of recipes (sweet and savory) with pumpkin again...

  13. My son would be the happiest boy in the world if I made these. I better get baking!

  14. Dawn:
    This looks so good. I've got to make it, just have to. I'm so jealous that you live in Cape Cod. We love Nantucket and used to go once a year before we moved West. There is nothing in the world like Fall in New England. I would just love to eat your crumb cake and then head outside to do some leaf peeping. I know it's too early now, but in about six weeks....

  15. Dawn, this is exactly how I make crumb cake too, isn't it the best? It totally slays people. I swear, we are seperated geniuses :)

    Fall is my fav because of the smells and baking too. Cinnamon, cloves, spices... but no one here put the ultimate down... PUMPKIN PIE :) Who doesn't love that?

  16. Not only peanut butter and jelly but also crumbs! ...mmm...

  17. Great creativity! I love cooking making soups so whenb the weather gets cooler, I am ready to get out the soup pot. And fall reminds me of football season...lots of good munchies!

  18. PB & J! How can this be bad. YUM!

  19. I like peanut butter. I like jelly. Most importantly I like crumb cake. Hmmm...I likey!!!

    Fall is also my favorite season. Apple picking, the start of braising, warmer clothes, and sleeping with the windows wide open.

    Looks amazing!

  20. Dawn:
    Thanks so much for asking about Gramps. Holding steady for now! Fingers crossed.

  21. I love fall and these bars look perfect!! I like making pumpkin and apple recipes...and watching football of course!

  22. I'm totally with you on fall! I love cooking/baking with pumpkin and I can't wait to pick apples and then make some sort of pie or cake! I have a great recipe somewhere for Apple Pumpkin Bread and I make it every Thanksgiving.

  23. What reminds me of fall? Well for one, the leaves are already changing up here! School buses, pumpkins and fresh apples at roadside stands, and cool mornings.

    I think my kids would love this crumb cake--maybe I'll be a nice mom and make it for them. ;)

  24. Superb crumb cake. Its a pity i cant dig into the screen and grab a bite :)

  25. YUM, Dawn! You and Adam are on the same wavelength! LOL!

    I miss fall in New England something TERRIBLE! That is why we go every October. I am so looking forward to that trip in a few weeks! YAY!

  26. Oooh, this looks deadly. Naturally I love this combo and crumb cake is a great childhood memory for me. My mom used to buy the Entemann's crumb cake and I would usually eat about half of it for breakfast. Terrible breakfast really, but so delicious! This looks even better.

  27. Squash. I love fall squash.

    But there's always been a special place in my heart (and stomach)for peanut butter and jelly.
    Your crumb cake looks delicious, and I must make it!
