Peanut Butter & Blueberry Pupcakes

peanut butter and blueberry pupcakes cupcakes
It’s that time of year again, Finn’s birthday!  Big birthday boy!

He’s a whopping six years old now.  Goodness, how does that even happen?!  I swear, time moves so brutally fast.

Last year I baked up those Pumpkin & Peanut Butter Pupcakes for him, which he seemed to enjoy.  But this year, as I like to do, I baked him up something new.

He is such a weird dog.  And I think he gets weirder by the day.  On his own, mind you, he’s not mimicking his parents in any way.  Or at least not me, ahem.

hahahaha, what timing with the camera here!
He’s been with us now for four and a half years (huh, seems like longer [not in a bad way]) and every single day he does something odd or strange or cute or whack-a-doo or all four, we can’t help but laugh and shake our heads.

He still doesn’t like people.  He still doesn’t like other dogs.  Or cats, cats are the worst.  Toby the neighbor marshmallow puff dog is his mortal enemy.

Finn has no siblings.  He doesn’t realize what he’s missing, the fun he could be having running around all day breaking the house, poor guy. 

Mike and I still can’t travel anywhere together because of these issues.  No one can come visit us at our house.  Or, well, they can, so long as they stay outside.  Fifty feet away.  No dinners, no entertaining.

We make good on our commitments though and Finn is our commitment, in his forever home.

Finn’s birthday, Mike decided upon his adoption, falls on Mike’s birthday so needless to say, but clearly I’m gonna, the Week of Mike is a doozy.  Lots of baking going on.

Finn's empty plate
It’s a hit!
Recently I’ve cut out yet more people-food items from Finn’s diet, namely pumpkin.  Is he allergic to it?  I don’t know.  I thought I’d try to cut that and sweet potato out to see if the itchy ears, red schnoz, and cookie-tossing tummy would improve. 

Nope, not really, except maybe for the latter.  Though he now gets digestive enzymes twice daily so his tummy heave-ho are less frequent so, heh, I’m on the right track somewhere.

Ah German Shepherds.  So complicated!  He sure is a handful, that dog.  Good thing we like him!

This is all probably more than you ever wanted to know about finicky Finn and his wacky insides but this does relate, in that eliminations resulted in a search for new dog-friendly recipes that left out pumpkin.  

Since it’s blueberry season and blueberries are so healthy and they’re something he can still eat, I wanted to include blueberries.

Thankfully I came upon a good place to start with Flying on Jess Fuel’s Bacon Peanut Butter Pupcakes.

Made a few changes though, the first being bacon.  As much as I’d love to share the Joy That is Bacon with Finn, bacon is processed and much too salty.  Dogs, nope, don’t need that.  I know, I know, it’s just a treat, not his everyday food; I’m a terrible mom.

These are so quick and so easy, in less than forty five minutes, the big birthday boy was chowing down on a big birthday boy treat!  Plus it’s a small batch too, only six cupcakes, so leftovers spoiling is minimized if you’re a one dog household or have a smaller pooch.  You can even freeze these too, dole ’em out here and there.  Oh, serve ’em mostly frozen on a hot day!  Oh that’s fun!

It’s pretty much a dump and run recipe, add the ingredients to a large bowl, mix ‘em up…

No mixer required, just grab a big ol’ bowl and spatula!
….add your blueberries (either fresh or frozen are fine, mine happened to be the latter), gently fold those in.

Careful with them there blueberries, don’t wanna pop and squish ’em
Divide the batter between the six cupcake liners and bake!  Tada, happy dog happy dog!

Yeah, I used a plate to serve him a half a pupcake to celebrate his big boy day despite being quite confused about plates still.  He must’ve been previously trained that people plates are to be avoided so he gets rather weird about it.

“Mom…ma, mommy, I don’t get this white thing!  You’re makin’ me nervous here…” as he pushes everything off the plate.
Usually we end up putting baked good nummies in his regular food bowl at which point he’ll then eat them.

Lookin’ sharp there celebratory pupcake!
Once he got going though, he very much relished in this cake and scarfed it down.  Yay, see?  Mommy’s not so terrible after all!

Finn getting a helping hand from Mike to eat
Ok so Daddy had to lend a hand of encouragement. Darn plate.
Maybe?  Maybe he’s finally starting to catch onto the goodness of baked goods?  I sure hope so as I fully intend to keep baking for his oddball self.

Looking for some excellent people birthday treats too?  Be sure to check out these cakes!  Woot woot, happy birthdays!

Share your thoughts :

  1. The pupcakes look great! Do you think I could put the vatter into my dash dog treat maker & bake them in there?

    1. Thank you! And thank you for introducing me to that nifty gizmo! I haven't tried that maker but I imagine you could give half a batch a whirl, see how it works. Check the instruction booklet, there are likely handy tips there. You could try my Barky Bucks recipe which you can find via the search bar as those are crunchy ones. Let me know how it all works out! Thank you for the great question!

  2. Thank you soo soo much!! I followed everything and made it into a 6-inch cake. Perfect size for my dogs! Cake was so soft and fluffy! Our dogs absolutely loved it!

    1. Oh terrific! Thanks for letting me know a 6" cake worked out perfectly, I appreciate that info! So thrilled your dogs loved it! Thank you!
