Haaaaaapppppppppyyyy Friday!

In celebration of being on the verge of one of these glorious things called the weekend, I bring you waffles. Whole wheat and oat cinnamon rhubarb waffles to be exact. I can’t lie. I’ve become a bit waffle-obsessed. I can’t stop thinking about all of the waffle possibilities. Of course we have sweet waffles. We also have savoury waffles. But then we have waffle sandwiches. Waffle donuts. And I bet waffle nachos could totally be a thing.

Today we’re keeping it pretty simple. We’ve got whole wheat flour and oats for some hearty oomph. The rhubarb adds a little tartness (PS. You could totally sub in apples for the rhubarb). And there’s cinnamon and brown sugar for flavour. Think: rhubarb crisp in waffle form. And if you want to go all out, you can top the waffles with butter and a sprinkling of cinnamon sugar. Boom. If that doesn’t start your day off right, I don’t know what will.

It’s the weekend, friends! Enjoy, relax, live it up, treat yo’ self, and eat some waffles. In that order.

Whole Wheat & Oat Cinnamon Rhubarb Waffles (adapted from Taste of Home)

These hearty waffles taste delicious with butter and cinnamon sugar (simply combine 1/4 cup sugar with 2 tsp. cinnamon), or fruit and syrup. If you can’t get your hands on any rhubarb or if it’s not your thing, feel free to use apples instead. Makes 6 waffles. 

1 1/2 cups whole wheat flour

1 cup oats

3 tsp. baking powder

1 1/2 tsp. cinnamon

1/4 tsp. salt

2 eggs, lightly beaten

1 1/2 cups milk

4 TBSP. butter, melted

2 TBSP. brown sugar

1 1/2 cups rhubarb, chopped

In a large bowl, combine the flour, oats, baking powder, cinnamon, and salt. In a separate bowl, mix together the eggs, milk, melted butter, and brown sugar. Add the wet ingredients to the dry, along with the chopped rhubarb. Mix until just combined. Cook according to the instructions of your waffle maker. Refrigerate or freeze leftover waffles, and reheat either in the toaster or the oven.

  1. AMANDA! YES! Waffle nachos could totally be a thing. And in the meantime – and probably even after – I’ll eat your cinnamon rhubarb waffles. I love the fruit and oats and everything good here. It’s Friday here too – please make me some. Thank you.

  2. Well I have two choices now: Make these amazing waffles this morning as a second breakfast or make them tomorrow for breakfast. I choose BOTH.

  3. this recipe is making it really hard for me to go through life without a waffle maker!

  4. I love a good weekend breakfast, and waffles are such a treat. And these waffles are so different and looks hearty and delicious! It’s making me want to run out and get a waffle maker. Somehow, I’ve managed to hold out on one…

  5. YES to these waffles! I wish it were the weekend all over again so that I could enjoy my morning pot of coffee alongside these delicious beauties. I’ll save them for another weekend 😀 The rhubarb idea is juuuust killing me. I’m licking my chops in anticipation!

  6. Annnd I officially need a second breakfast now!

  7. Yum! These would make a great weekday dinner too! I’m not sure about the waffle nacho idea though 🙂

  8. Yay for waffles all day every day! I love the idea of stuffing them with rhubarb….bookmarked for when it is back in season!

  13. Well, I love anything ‘rhubarb’ so why not rhubarb waffles? I think I need to get myself a waffle iron quick sharpish. I love that you’ve added in oats and wholewheat flour – I certainly wouldn’t feel guilty having these every day for a week for breakfast!
