Peanut Butter & Jam Oat Cake Sandwiches

I was struggling to find the appropriate name to call this recipe. I haven’t seen anyone make something like this before, yet it’s such a simple concept for a healthier recipe! 

Ideas come to me when I least expect them. Weirdly enough I usually get them when half asleep – either while falling asleep or waking up. When I sit down and try to think of creative new ideas, they just won’t come to me. It’s almost like I have to wait for an epiphany.

These peanut butter & jam oat cake sandwiches make such a great healthier dessert. I love making no bake treats with minimal ingredients, and this recipe is exactly that – you only need 6 ingredients to make them. I made my own chia jam since it’s so easy to make and better for you than shop bought (with less sugar, more fruit/fibre/antioxidants & healthy fats), but if you’re short on time or don’t feel like making your own jam, please feel free to use your favourite shop bought jam.

They have the perfect balance of sweet (from the jam & chocolate) and salty (I love topping them with a pinch of salt to enhance all the flavours). They also have the most satisfying crunch from the oat cakes as well as the chocolate shell. 

You can easily adjust the recipe to your liking/dietary needs. I’ve made them with tahini before (for a nut-free option), but really you can fill them with anything you like. Allow your creativity to run wild! The first time I made something similar was when I created these mango ‘sandwich cookies’ last year. A simple recipe basically made up of oat cakes, mango puree and dark chocolate. You can even create an ice cream version by sandwiching your favourite ice cream between two oat cakes, freezing, then dipping them in chocolate. I need to try that soon! 

The recipe makes 6 oat sandwiches, although I find that half a sandwich is just about right for me, so it would make 12 servings for me. 

They freeze well, so you can make them in advance, place them in a freezer bag and store for up to 3 months! This is definitely a recipe you’ll want to try, or at least play around with and create your own version 😉 

What you need to make these peanut butter & jam oat cake sandwiches:

Chia jam – it’s so easy to make your own at home. I usually make a big(ish) batch on a Sunday to add to my morning porridge or spread on some toast/add to yoghurt when I’m feeling snacky. All you need is chia seeds, raspberries and a drizzle of sweetener. You can use fresh or frozen raspberries, or use other types of berries. If you don’t feel like making your own jam for this recipe, you can always use shop bought jam 🙂 

Oat cakes – I always have oat cakes in my kitchen cupboard. It’s such a handy snack in between meals. I usually enjoy them with hummus, but I had the idea to use them in a sweet recipe. They’re mild tasting, so work very well in this recipe since the peanut butter, jam and chocolate all have quite strong and distinct flavours. If you want them to be gluten-free make sure you use gluten-free oat cakes!

Peanut butter – I used smooth peanut butter, but you can also use crunchy or any nut butter for that matter. You can even use a seed butter like tahini if you want a nut-free version. 

Dark chocolate – I always use 70% dark chocolate, not only because it’s healthier, but because I think it tastes SO much better than milk chocolate. Packed with antioxidants and most good quality dark chocolates tends to be dairy-free for those avoiding dairy.
