Peanut Butter + Banana Ice Cream Sandwiches

Before college, the combination of banana with peanut butter was unfathomable to me. However, during my Freshman year, that all changed. Bites of ripe banana interspersed with smooth, creamy peanut butter soon became my snack of choice. As a mix of protein and sugar that could store well unrefrigerated, it was this busy college student’s perfect midnight study break snack.

Years later, one ingredient banana ice cream is now a staple in my home. I love that I can get the sweet, frozen creaminess of ice cream with a single natural ingredient, the humble banana.

Even peanut butter frequently shows up in my cooking, but rarely in the now-classic combination of peanut butter and banana.

So, today, I want to throw it back to my college days with an indulgent twist—a Peanut Butter + Banana Ice Cream Sandwich!

I began with making the peanut butter cookie crusts. In my Kitchenaid Mixer bowl, I creamed together the peanut butter and brown sugar.

Once it was all uniformly combined, it was time for the dry ingredients. In a separate bowl, I combined the dry ingredients: my Quick Homemade Oat Flour, baking powder, and salt.

Then, I added the dry ingredients to the wet ingredients.

Once thoroughly combined, I added the final cookie crust ingredient, milk. These Peanut Butter + Banana Ice Cream Sandwiches can easily be made to be vegan by substituting in a nondairy milk. I had some milk on hand that I wanted to use, so I went with the dairy option this time.

After the milk was mixed through, the dough had a firm consistency, perfect for easily rolling out.

On a baking sheet layered with my Silicone Baking Mat, I rolled out the dough into a large sheet. Using a fork, I patterned out hatches to add visual variety to the peanut butter cookie crust.

Then, I popped the tray into the preheated oven for baking.

While the peanut butter cookie crust baked, I quickly whipped up my five-minute, one-ingredient Banana Ice Cream.

Once baked, I removed the tray from the oven and let the cookie cool and harden.

After the cookie completely cooled, I cut it in half and scooped out some creamy banana ice cream.

I spread out the ice cream edge to edge and placed the second half of the cookie crust on top.

In my excitement, I tried slicing up the sandwiches and ended up with a bunch of banana ice cream squishing out. So, I recommend practicing patience and waiting until the entire block freezes completely before slicing through.

After waiting for the sandwiches to freeze through and cutting them into individual sandwiches, I finally reaped the reward.

The finished Peanut Butter + Banana Ice Cream Sandwiches were great! They paired wonderfully with a glass of cool milk, and the best part is that they keep in the freezer, so I’ve been able to enjoy them on nights when I’m yearning for a slightly indulgent, midnight snack.
