Introducing: Mr. Peanut Butter Cake Batter, my favorite shake flavor of all time. I know he’s a little green, which seems a strange color for peanut butter and cake batter, but trust me on this one. I wanted some color, just for fun, and I also wanted some veggies, so fresh spinach seemed like the way to go. I’ve used blue food coloring before to turn him a more authentic “frosting” color, but my little sis throws a fit when I use food coloring (and I thought some of you might, too). Hence, the spinach. Katelyn (my sister) loves spinach. Like, a lot. Like, to the point that some good friends of ours gave her a bag for her birthday. She was tickled pink…er….green.
I think most of you have come to appreciate my peanut butter milkshake recipe. I’m sure that a lot of you have also had some sort of cake batter shake at some point. Combining the two was a natural step in my mind, especially since I often eat cake and ice cream with a dollop of peanut butter. Everything is better with peanut butter, especially if your last name is Thomas. We are known for our obsession with peanut butter (my dad has added it to meat and cheese sandwiches, hamburgers, sliced cheese, pancakes, oatmeal, ice cream, and quite a few other things ever since I can remember).
PS – I recently updated my peanut butter milkshake recipe to make it thicker, so if you haven’t printed the new version, I highly suggest that you do so!

I hope that you can look beyond the outward appearance of my milkshake and whip up one for yourself. I don’t think you’ll be disappointed! (Don’t worry – you can’t taste the spinach. Not if you just use a handful, that is.)
As always, feel free to check out the Notes section of the recipe for answers to FAQs. The “suggested products” section below the recipe has links for products that I use and recommend.
