Blueberry Banana Oat Crumb Muffins

I had a completely different post scheduled for today. But then I made these muffins and changed my plan at the last minute in a fit of excitement because these. muffins. are. LIFE.

Nothing beats the smell of blueberries baking on a warm summer morning. Whether you’re incorporating them into pancakes or folding them into muffin batter, there’s something incredibly nostalgic about that warming berry aroma. And I had a strong hankering for that sense of nostalgia, so I decided that this was a great opportunity to make blueberry-filled muffins.

And to break up the army of brown bananas in my freezer.

I don’t bake often. That’s no secret. But when I do get around to it, I like to pretend that I know what I’m doing, and it usually works out pretty well in the end.

I found a good recipe for Banana Blueberry Crumb Muffins here and made a few alterations; I swapped the white sugar for maple syrup, the brown sugar for coconut palm sugar, I brought walnuts to the mix, and I added oats to the crumb topping.

Oh, I also replaced the usual old egg with a local duck egg from my friends farm over at Mabel’s Acres! But you can use a regular egg, of course.

Because my husband and I are savages, I take my muffins (and most of my baked goods) out of the oven about a minute or two early. We love the extra moistness and chewiness of slightly under-baked treats and it works oh-so-well with these bad boys.

But you do you. Bake them until they’re cooked through if that’s your jam.

  • Reply Justine @ JustineCelina.com July 17, 2017 at 1:19 pm You've gotta love those last minute baking sessions that turn out to be blogworthy! These look so yummy and I'm always looking for innovative ways to use up the mountains of bananas in my freezer, too. :) Pinning for future reference and can't wait to try it -- I have a shipment of BC blueberries arriving on Wednesday! Hope you had a great weekend, love.
    • Reply Killing Thyme July 20, 2017 at 11:44 am Thanks, Justine! I see you received your shipment of blueberries this week — I'm excited to see what you do with them!
  • Reply diversivore July 15, 2017 at 11:19 pm I'm wiiiiith you. Blueberries forever... and blueberry muffins ARE life. I've never made them with bananas before though, and given my love of banana bread (also a deep and abiding love), I'm all over this idea. I don't blame you for changing your posting plans. This is amazing.
    • Reply Killing Thyme July 20, 2017 at 11:43 am Haha, thanks Sean! I definitely need to buy blueberries more often.
  • Reply Colleen Milne July 14, 2017 at 8:34 pm Dana, these muffins...I love everything in them, the blueberries, walnuts, maple syrup, oats and the coconut sugar, which I use, too. And I too, have that army of frozen bananas in the freezer. So this may be just the solution, thanks!
    • Reply Killing Thyme July 20, 2017 at 11:42 am Thanks, Colleen! I love when recipes help us clean out the ol' freezer or crisper. I made a crisper-cleaning quiche yesterday, haha.
  • Reply Ayngelina (@Ayngelina) July 14, 2017 at 2:36 pm What is coconut palm sugar? I can't believe I've never heard of it.
    • Reply Killing Thyme July 14, 2017 at 4:27 pm It's a natural sweetener. I use it in place of brown sugar because it's got a deep and almost caramelized sweetness to it that's very similar.
  • Reply Ayngelina (@Ayngelina) July 14, 2017 at 2:32 pm An actual healthy muffin? Sign me up!
    • Reply Killing Thyme July 14, 2017 at 4:27 pm Healthy-ish, anyway ;)
  • Reply Gabrielle @ eyecandypopper July 14, 2017 at 11:51 am MMMmmm! those look so good! You're right, nothing beats the smell of freshly baked muffins in the morning. I actually love baking, I find it relaxing, and unless you're making a fancy dessert, it's not as precise and complicated as people think it is. Baking a dozen muffins is pretty forgiving, and I love that. I recently made some blueberry muffins too, although yours look better, and I just love the explosion in my mouth! haha I think you've got a winner on your hands! Next time, try spelt flour, it adds a nuttiness flavour, it's great!
    • Reply Killing Thyme July 14, 2017 at 4:25 pm Yeah, baking *can* be relaxing if it's something simple like muffins. Or banana bread. I can't handle cakes or icing cupcakes though, that's for sure. Haha. I'll definitely have to find some spelt flour! It's great for pizza dough, too.
  • Reply Jess | Oil and Garlic July 13, 2017 at 9:54 am These muffins look delicious! Going to try them soon. Your photos are beautiful as well :)
    • Reply Killing Thyme July 14, 2017 at 4:24 pm Thanks, Jess! I hope you love them :)
  • Reply Christina Conte July 12, 2017 at 5:34 pm After seeing these, my deduction is that really SHOULD bake more often, Dana!! WOW!
    • Reply Killing Thyme July 12, 2017 at 7:43 pm Haha, thanks so much, Christina! I appreciate that! I think after these bad boys, I just might :x
