White and Dark Chocolate Banana Squares

Ok so I keep saying how easy my recipes are right? Well this is another one. Not only it is easy but it is much better for you than the regular versions out there. It is super spongy and tasty and you would not even notice that is has whole wheat flour.

In this recipe I used both oat and whole wheat pastry flour but if you don’t have oat flour you can substitute with barley or simply use all whole wheat. You can also double the batch, which is what I always do because sweet things around my house hardly last :-)

  1. These sound wonderful! I just found your blog..you have some great recipes!

  2. Thanks so much, let me know if you try any :-)

  3. Miryam.. I finally made these over the weekend..they were wonderful! My boys loved them!
    I’m going to try the Wild Berry, Strawberry Lemon cake next! Thanks for the great recipes.

  4. Cool, let me know how it turns out, I suggest you also make the pineapple and coconut cake if you like those flavors. I made it the other day and I am thinking of getting the pineapple again tomorrow to make another one. It only lasted two days ;-)

  5. Wow, what an amazing recipe! Just perfect for what I had on hand…a whole bunch of ripe bananas and no butter. I doubled the recipe and omitted the cocoa powder and it made a beautiful 9×13 and 9 small muffins. I also didn’t have oat flour so I subbed oat bran and ww flour for the oat flour.

  6. Love your recipes, but I don’t eat eggs…can you suggest what can I use instead? Thanks.

    • Believe it or not, hearty-healthy flax seeds can be used as an egg substitute! Simply mix one tablespoon of ground flax seeds with 3 tablespoons water until fully absorbed and viscous. Use in place of one egg. (You can use pre-ground flax seeds or grind them yourself in a spice or coffee grinder.) Thanks for stopping by, I hope this helps :-)

  7. Thank you so much….will definitely try it

  8. Just made these, they are in the oven as I type. Cant wait to taste them!! Thanks for your wonderful recipes.
