It turns out that tart zippy rhubarb is the perfect complement to sweet cinnamon-scented breakfast bread. Run to the market, grab some rhubarb and zucchini and get ready to make this perfectly moist and super delicious wholesome zucchini bread- with a rhubarb twist!

INGREDIENTS YOU WILL NEED TO MAKE THIS RHUBARB ZUCCHINI BREAD

This isn't an all-encompassing list but rather a few highlighted ingredients. 

• Rhubarb – You should be able to find this at most farmers markets and grocery stores through early August. For nutrition information on rhubarb, check out everything you need to know about rhubarb here.
• Zucchini – It's that time of the year when most gardens are overflowing with zucchini, this is the recipe to use it up on! 
• Oat Flour – If you don't have oat flour on hand, don't fret. You can make your own oat flour by blending rolled oats in your blender or food processor until it resembles flour. 
• Walnuts – Rich in healthy fats and walnuts add the perfect nutty deliciousness to this bread.
• Chia Seeds – You can easily make this recipe without the chia seeds but I love the extra addition of heart-healthy omega 3's.
• Honey – My preferred sweetener for this recipe is raw honey. honey pairs so beautifully with citrus and rhubarb!

WHAT IS RHUBARB?

Many people tend to think that rhubarb is a fruit, but it's actually a vegetable. It can be grown all year long and is usually one of the first vegetables to start growing and ripening in the spring. 

IS RHUBARB TART OR SWEET?

Rhubarb is tart, but typically paired with sweeter flavors. I think it tastes like a cross between a cranberry and a green apple. As you bake or cook rhubarb it becomes sweeter.

HOW WILL YOU KNOW THIS ZUCCHINI BREAD IS DONE BAKING AND READY TO EAT?

Great question. The simple way is to insert a toothpick or knife into the very center of the bread. If it comes out clean, it's baked and done.

If it comes out wet with batter, it needs more time. 

TIPS FOR BAKING WITH OAT FLOUR

Oat flour is an easy flour to work with, especially if you are gluten-free. However, there are a few things to know when baking with oat flour.

1. You can easily make your own by grinding rolled oats in a food processor or blender. If you have the flour/dry grains blender attachment for the vita-mix I recommend grinding oat groats (or steel-cut oats) rather than rolled oats. 
2. Oat flour can produce a gummy texture, especially if you are using flour from rolled oats which have already been pre-cooked, thus producing a gummier cooked texture. 
3. To reduce the gummy texture you can either purchase oat flour, grind steel-cutn oats, or blend oat flour with rice flour. 
4. Oat flour is 1:1 replacement for wheat or white flour. 

Go ahead and start grating zucchini because this beautiful bread is just begging to be baked in your kitchen. If you need any more reason to get baking right now here are 5:

• Wholesome
• Sweet and tart
• Perfectly nutty
• Satisfying
• Easy Peazy!
