Cap'n Crunch Peanut Butter Milkshake Finished

In honor of the best holiday of the year, behold the spooky spectacle of a homemade Halloween Cap’n Crunch milkshake. Unfortunately, the Cap’ns gimmicky ghoulish green glow is lost once blended with ice cream, sans ecotplasm, but you can still taste the difference (not really). That aside, you may have seen me rave about the Cinnamon Toast Crunch Milkshake from Buger King, but I am here to not so humbly state that this homemade diabetes delight eats it for…



how about, cleans its cinnamon clock?

Yeah, lets go with that.

Cap'n Crunch Peanut Butter Milkshake Soak

To be fair, with Graeters doing the heavy lifting in my cereal shake, comparing the two is about as fair as pitting a rancor against a poodle. Flying Dutchman’s Frightful Delight captures the purest essence of a cereal milkshake and is easily customizable with other cereal celebrities beyond the good Cap’n.

Cap'n Crunch Peanut Butter Milkshake Ingredients

Adapted from Cap’n Crunch Milkshakes



  • 1 Cup (202 g) Vanilla ice cream or other ice cream of choice (this quantity can be adjusted to achieve desired consistency) (I used Graeters Madagascar Vanilla Bean and it was phenomenal)


  • .75 Cups (180ml) milk of choice (more or less depending on the desired consistency, I used cashew milk)


  • 1.5 Cup (52g) Cap’n crunch cereal of choice with some reserved for garnish (or just use more, there’s no such thing as too much cereal in my world)


  • 1/4 Cup (64g) creamy peanut butter (also consider another tablespoon or 15 grams or so melted to drizzle on top)


  • Whipped cream for topping if desired



Pour the not so salty seaman’s delicious, and in this case spooky, booty into a container and send it to Davey Jone’s Locker (in other words, add milk). Soak for about an hour, giving the mixture a stir or shake a few times. I used my Ninja Blender and kept the same cup for the entire process.

Once you have a bowl of mush you wouldn’t actually eat, add it to your blender with ice cream and peanut butter. In theory, one could strain the milk and simply use that, discarding the soggy cereal. This is an offense that falls just shy of animal torture in my world, but you do you, I just don’t want to know about it.

Blend until smooth and add milk or ice cream until desired consistency is reached.

Pour into glasses and top with whipped cream, extra cereal (crushed or whole) and drizzle with melted peanut butter if you so desire.

Pledge your eternal soul to the Dutch’s crew for bringing you this deliciousness, and if you find his sock, don’t forgot to use your other two wishes wisely.
