Adzuki Bean Nutella Brownies (Vegan + GF)

Adzuki Bean Nutella Brownies (Vegan + GF)

I decided to make these Adzuki Bean Nutella Brownies because black bean brownies seem to be all the rage lately, but I thought adzuki red beans might be better suited, as they’re used in a lot of traditional Japanese desserts. Adzuki is a type of red bean grown in Eastern Asia that’s quite similar in size and texture to black beans, and they’re recently being hailed as a superfood.

Red bean paste is used as a filling in lots of Japanese sweet snacks such mochi (a cake made from sticky rice), dorayaki (red bean paste sandwiched between two pancakes) and anpan (a sweet bread roll filled with red bean paste).

You can buy adzuki beans either dry or in tins from most supermarkets. 

So these brownies are great because they’re really healthy, full of protein + fibre, low sugar, grain-freegluten-freedairy-free and you can easily make them vegan

…but all these health perks aren’t why I’ve decided to blog about them – they’re the easiest brownies I’ve ever made AND the most deliciousThey’re actually richer, fudgier, more gooey and taste more indulgent than any other brownie I’ve ever made with flour, sugar and butter. 

The beans make the texture a lot denser and fudgier, while the dates and date syrup add a caramel-like sweetness and the Nutella adds extra richness and flavour. And the recipe is pretty versatile too – if you don’t like Nutella, you can swap it for regular chocolate spread, any kind of oil (such as vegetable or coconut) or nut butter (such as almond or cashew). You can either use a shop-bought Nutella (ensure it’s vegan/dairy-free if necessary) or make it yourself (it’s ridiculously easy, and you can scroll down to see a recipe). Bear in mind if you’re using shop-bought Nutella you might want to decrease the amount of date syrup you use as it’ll make it a lot sweeter.

I like to add some chocolate chips or roughly chopped pieces of chocolate so you can get bursts of extra chocolate-y flavour when you’re eating the brownies.
