    Very dry! I think the oats take over the flavor & texture.

      I’m so sorry they weren’t a hit for you due to the oats!

    Okay these are AMAZING! Such good flavor and I love the flour/oat combo in the base. I had a lot of macadamia nuts on hand, so I used those instead of walnuts and it was such a great substitution! I also used homemade apple butter instead of applesauce. I will be making again, thanks for a great recipe!

    • replied:

      So glad you love them!

  • says:

    If I didn’t want to use apple sauce would I use1 full cup of oil?

    • replied:

      Not sure how this would turn out. I have only tested this recipe with applesauce and would recommend sticking to the recipe for best results!

    These are wonderful! I had to eat two right away. I’ll definitely be making them again.

      YUM! Glad you are loving these muffins, such a staple!

    These are the healthiest muffins on the planet!! I love to bake healthy and I’ve made these at least three times.
    So many recipes I see have a cup of butter and lots of sugar. No wonder people are overweight.
    Thanks for the best blueberry muffin recipe ever!

  • says:

    I haven’t made these yet — not sure if I will. How are these considered healthy with a quarter cup of added sugar? If I can figure out a way to replace sugar in this recipe, I look forward to trying it…..

    • replied:

      “Healthy” is a totally subjective word, and in my opinion, 1/4 cup isn’t a lot for a whole batch of muffins, but totally up to you if you want to make them!

    These are the best blueberry muffins I think I”ve ever made (and I have made many!) I didn’t have pastry flour on hand, so just used regular whole wheat flour. I added an additional 1/2 c blueberries because my 2 year old loooves them, and used pecans instead of walnuts. They turned out perfectly. Bookmarking this one for sure.

    • replied:

      I’m so happy to hear that!! Glad you and your little one both love them 🙂

    This is the most amazing recipe, it’s so satisfying, filling and full of flavor. So incredibly moist! I made these in a square baking pan and cut them into bars. I also wanted to try a slightly different variation, I replaced the blueberries with chopped up dried apple pieces, I added raisins and replaced the walnuts with pecans. I did add more cinnamon to both the batter and topping. Very yummy, I loved the blueberry ones along with my second variation so much, my mom is on a heart healthy diet and she has these muffins/bars in the morning for breakfast! Thank you for such a wonderful recipe!

    Just made these this morning and YUM. Blueberry muffins always feel very hit or miss for me, but this one was a hit! I used regular white flour as that’s what I had on hand, and I left out the walnuts in the batter, but included them in the topping, which is definitely a must (such an easy extra step that pushes this muffin into the fantastic category). I’m glad I made a double batch!

    • replied:

      Oh amazing!! So glad to hear you loved these, Zoe 🙂

    Loved the explosion of blueberries in this! The amount of sweetness was perfect for me. Will make again.

    • replied:

      Absolutely! Glad you enjoyed!

    Yummy muffins! I halved the recipe, subbed in AP flour and pecans, and added a little brown sugar to the topping. So good and easy to make!

    • replied:

      I’m glad that worked out well! Such a great snack or breakfast 🙂

    Using a silicone muffin tray requires about 4 extra minutes.
    Great recipe (once you have all ingredients on hand!)

    • replied:

      Great tip with the silicone tray – glad you enjoyed!

    incredible!

    We loved this recipe though we had several modifications due towhat we had on hand. Instead of applesauce used the meat from a small round gourd like squash we grow. No Walnuts so a mixture of hemp and ground flax seeds. Also forgot the oats in first batch with kids helping but turned out awesome. Second batch baking now with the oats and some chia added. We will see how that turns out! Thank you Monica.

    • replied:

      Glad those swaps worked out for you guys! Such a great snack 🙂

  • says:

    Can you cut the blueberries in half

    • replied:

      Sure!

  • says:

    I cannot wait to try these! My son loves muffins for breakfast, but we are trying really hard to instill better eating habits than we were given as kids. This will be the perfect solution! Would there be a difference between using regular rolled oats vs. quick cook rolled oats? We have the quick cook kind, but I want to make sure I do it right! Thanks!! xoxo

    • replied:

      I hope he loves these ones! Perfect breakfast. I think quick oats would work too!

    These have nice texture and moisture. As intended, they are not very sweet so I added a glaze to mine. Cream cheese would be divine!

    • replied:

      A glaze sounds delicious!

    I didn’t have applesauce so I subbed in the same quantity of mashed bananas and that worked fine. These muffins rise well and hold together well and the streusel topping is excellent. I also baked some with muffin cups and some just by buttering the inside of the muffin tin itself and they turned out great both ways, so I don’t think the muffin cups are necessary.

    • replied:

      Perfect! And I’m glad the muffin tin itself worked out well.

    I made these for my military guys without the topping and they looooved them! I made 3x batches (36) with fresh blueberries that were just bursting like gushers candy. They were a perfect healthy breakfast snack on the go!

    • replied:

      Yum! So glad they loved them 🙂 These are awesome for breakfast.

    I made them yesterday and they very delicious! Very moist. However I would like them just a little bit sweeter. I noticed your struesel topping does not include sugar ( most recipes do). So I will try adding some sugar next time.

    • replied:

      I wanted to keep these pretty low in sugar (to have them for breakfasts, etc.) but feel free to add a bit to the streusel!

      I used one cup organic regular flour and 1/3 almond flour. Turned out great.

    You are probably quite busy to answer questions, but could I use regular milk. I love making healthy muffins for my son but we haven’t introduced nuts yet. Thanks so much! Love your site!

  • says:

    Any suggestions on the topping without nuts….besides the chopped apple? thanks
