Why You’ll Love This Delicious Oatmeal Walnut Bread

Incredibly moist and fluffy, this oatmeal walnut bread is perfection thanks to the white cake mix.

I also love how the walnuts give it a crunchy interior without being overwhelming.

Made with wholesome ingredients such as rolled oats and walnuts, this bread will become a favorite I’m sure of it!

Ingredients You’ll Need To Make This Simple Oatmeal Walnut Bread

White Cake Mix – I used this one I love Betty Cooker cake Mix (not affiliate) just because I know for a fact that my bread or cake will turn out perfect every time.

Rolled Oats: Personally, I prefer rolled oats any day over instant oatmeal. That being said don’t restrain yourself from doing this oat walnut recipe if you only have instant oats in your pantry. Indeed, the result will be very similar, it’s just a personal preference.

Walnuts: 1 cup

Eggs: 3 eggs are what’s needed to keep your bread together.

Milk: I use 2% milk, but feel free to replace the cow milk with any vegetal milk without any issues. You can easily turn this recipe lactose free!

Canola Oil

Brown Sugar (optional): I love topping the oatmeal walnut bread with brown sugar, it gives the crust its dark brown color and I’m here for it!

Did you know that oatmeal bread was first made in Britain?
In fact, that’s where the first oat bread factory was established in 1899.

✦✧ Fill the loaf pan 3/4 to let your oatmeal bread expand.

How to Store Your Walnut Oat Bread?

You can store your freshly baked oatmeal walnut bread in the fridge for up to 7 days.

That being said, this yummy oat bread doesn’t last 7 days in my home!
