PERFECT FOR FATHER'S DAY! Peanut Butter + Brownie Chunk Milkshake #FathersDay #milkshake #chocolate #brownie #peanutbutter

Father’s Day is just around the corner, and while I do not have any kids, I do have a couple children of the furry variety.  So I started to wonder…what if Maximus (Furry Kid #1) were to make me a Father’s Day meal?  What would it be?  I’m guessing it might be Banana Pupcakes. 

As a side note, I did make these for the dogs last summer.  They were cupcakes with ground dog food as a primary ingredient.  They smelled umm…interesting. 

But back to Father’s Day.  Ethel (Furry Kid #2) would probably become alpha-dog in the kitchen, which means that peanut butter would be involved somehow.  Both of my 4-legged children absolutely love ice cream, especially on a hot summer day. 

So with that in mind, if Maximus and Ethel were to make me a Father’s Day treat, I’m nearly certain it would be this Peanut Butter + Brownie Chunk Milkshake.  Too bad they won’t get to clean the dish after this one!  (On a serious note, dogs should never ever eat chocolate.)

Now that summer is finally here in upstate New York, I’ve been breaking out the ice cream machine pretty often.  I started with this Vermont Honey Ice Cream, and it is still one of my favorites.  But this Peanut Butter + Brownie Chunk Milkshake is seriously delicious! 

It’s peanut butter and chocolate together…how can you go wrong??  To make this milkshake even more special, I…err, Maximus and Ethel…started with homemade peanut butter ice cream.  You could totally just add a cup of peanut butter and a couple scoops of vanilla ice cream in a blender and still achieve a similar effect. 

Likewise, this recipe features brownies baked from scratch, and you could totally use a boxed mix instead.  (This brownie recipe is loaded with chocolate, which makes it super gooey.  Difficult to eat by themselves, but perfect for this milkshake!)

To all of the fathers out there (no matter whether your kids have 2 legs or 4), Happy Father’s Day!

  2. Not only does that milkshake look crazy awesome, the brownie chunks also look totally perfect. Nice and fudgy, the way I like them!

    1. Haha! Great use of Queen. And yes, this is the real life. I say that because I had milkshake everywhere after I took those pics! 🙂

    1. Thanks, Mercedes! This cream is so incredibly easy…all it requires is mixing. (and a way to make the ice cream of course…)

  3. Whenever I see concoctions such as this, I always ask, “Who thinks of this?!” Invariable I quickly forget this question and silently say a thank you to whoever is responsible. Wow!! What a great idea, and wonderful post!

    1. Haha…thanks, Dan! I really appreciate the compliment. (But trust me, there have plenty of failed attempts at deliciousness in the past, too. Ahem, Candy Corn Caramel Buns.)

    1. Bella Marchesa! This milkshake was amazing…I might have to remake it now for actual Father’s Day. haha. And that Vermont Honey Ice Cream is delicious. And it is SO much tastier with the sliced strawberries on top, too.
