Vegan Blueberry Muffins

I know that it's easy to get tempted to replace the oil/fat in a baking recipe with applesauce to make it fat-free, but that would result in dense and dry muffins. It won’t be as airy as using oil alone. So I would suggest just replacing half the quantity of oil with applesauce.

Since the acidic content of lemon juice is less when compared to vinegar you might have to double the quantity of vinegar. For example, if a recipe calls for 1 teaspoon of vinegar, use 2 teaspoons of lemon juice.

Lemon zest is nothing but grating the skin of the lemon. Care should be taken so that the inner white sheet from the skin does not peel away because it will be bitter. Lemon extract is like vanilla, and almond extract is in liquid form.

I wouldn't say that it's compulsory, but it will give these blueberry muffins a nice flavor without baking powder. You may choose to use orange zest/extract instead of simply vanilla extract will be good too.

Opening the oven door quite too often while it is baking makes cold air enter the oven and might be the reason for the muffins to sink. Another reason is that you used too much batter for each muffin.

No it doesn’t work like that. You would have to use Xanathan gum. I haven't baked this recipe gluten-free and have read that simply substituting the all-purpose flour with gluten-free flour would not work especially in baked goods that have to rise, like muffins, cupcakes, and cakes. Brownies and cookies should not be that much of a problem to bake gluten-free and can be done without xanthan gum.

Gluten-free and egg free is a lot of trial and error methods only. But some of the readers did mention that they tried this recipe gluten-free using rice flour and gluten-free mix (which already has the xantham gum in it). You may try it at your discretion. I will try to bake a gluten-free version shortly and blog about it soon.

Certainly you can. Just use dairy milk and if you prefer butter, melted butter instead of oil. One of the readers suggested that the muffins turn out better if oil is used instead of melted butter though.

Any oil that has a neutral flavor. Peanut oil, sunflower oil, (refined) coconut oil, avocado oil, etc could work on this homemade vegan blueberry muffins recipe.

You can try it at 350F but bake it a few minutes longer.

Halving the recipe may not work out always. It's again for you to experiment and see. Another option is to bake all the muffins and freeze the remaining and use it later. If you decide to halve the recipe and use a 12-cup pan, then you will have to fill the rest of the cups with little water so that the muffins will bake evenly and doesn’t get dried out.

You can try a flaxseed meal, but I’m pretty sure the muffins won’t be as airy and light as those with lemon and vinegar. You can blend a teaspoon of flaxseed meal with 3 tablespoons of warm water.

There are a couple of reasons for this:
1) If you try to peel off the wrapper while the muffins are still warm
2) If you make it low-fat or fat-free
3) If you don't lightly grease the liners with non-stick cooking spray.

The temperature does not change, but you need to bake it for a shorter time than you would bake regular-sized muffins. Somewhere between 12-15 minutes.

I have explained it in detail here: Why does fruit sink to bottom of the cake?

Rice milk is derived from cooked white/brown rice. You can use any other non-dairy milk like almond milk, oat milk, hemp milk, etc. I personally don't prefer using soy milk because it gives a sticky texture to the baked goods. For vegan baking, my choice is either rice milk or almond milk.

Yes you can use any other berries or fruits of your choice. Or even add-ons like nuts, chocolate chips, dried fruits, etc.
