These easy to make vegan sweet potato muffins are perfect as a breakfast, brunch or mid-morning treat! Delicious, undetectably vegan, and easily gluten free. Step by step instructions included.
Spiced Vegan Sweet Potato Muffins
These spiced vegan sweet potato muffins are perfect for breakfast, brunch or a mid-morning treat. They’re fuss free and easy to make – they’re a variation on my fail safe basic muffin formula that uses equal weights of wet and dry ingredients.
As always with muffins, remember that the batter should be lumpy; it will sort itself out as it cooks. If you over mix it, the muffins will be tough and have tunnels in the dough. I gently fold the ingredients together, with no more than 15 folds.
Why do you add vinegar to these vegan muffins?
Two reasons:-
Firstly adding vinegar to the plant milk causes it to turn to buttermilk which helps the muffins rise and adds flavour, lightness and a fine crumb.
Secondly the bicarbonate of soda reacts with the vinegar and helps to give the muffins some extra lift, and is why you need to bake as soon as you have mixed the batter.
The reaction between the vinegar and bicarbonate of soda starts as soon as the wet and dry ingredients meet. They react to product bubbles of carbon dioxide which gives the batter its mousse like texture which makes for a light and fluffy muffin.
Vegan Sweet Potato Muffins Variations and Substitutions
When adjusting a recipe, it is best to switch one thing at a time. This muffin recipe is fairly forgiving but still make adjustments one at a time. Here are a few ideas for variations:
Flour – I used regular all-purpose flour here. The recipe is forgiving enough to use different flour or a mix. If you use self-raising flour leave the baking powder out. You can also use gluten free flour if needed. Substituting some, or all with spelt flour will result in a slightly nutty muffin with a cakier texture.
Sugar– A less refined brown sugar will taste better here, and the flavours will pair well with the spices. I generally use a mixture of super fine (caster) white and a dark brown muscovado. The easiest way to get rid of lumps and clumps in brown unrefined sugars is to rub them between your fingers. A few small lumps will give you delicious caramelised little pockets of sugar in the muffins so don’t worry about getting rid of every lump. BUT you need to break up those big lumps before you mix in the liquid.
Milk – I generally use homemade unsweetened soy milk, to make soy milk at home see my post on how to make soy milk in a soup maker. Any milk (plant or dairy) will work her – use what you usually have in the fridge.
Oil – Again this is very adaptable – any will work. I tend to use sunflower but any lightly flavoured oil can be substituted. Rape / canola, light olive or corn oil. Coconut oil will work but completely change the flavour.
Spices – this recipe uses a traditional mix of ground allspice and cinnamon, but other combinations are well worth trying. How about including cloves, nutmeg, or a hint of ginger?
Toppings – I’ve topped these muffins with a few rolled oats, but I could have used some nuts: maybe lightly crushed walnuts or a sprinkle of sliced almonds. Or a little granola for the crunch.
This recipe makes 6 regular sized muffins, or 12 fairy cakes. Reduce the cooking time if making smaller muffins.
How to Make Vegan Sweet Potato Muffins – Step by Step
First things first – switch the oven on to warm up!
Step 1 – cook a medium sized sweet potato until soft, then peel and mash. I find the easiest way to do this is to pop the potato in the microwave and cook until soft, then mash with a fork on a chopping board.
Don’t throw any spare sweet potato away – you can throw the skin into soup, or we feed ours to Herbert the miniature wire haired dachshund!
Step 2 – pour the milk into a bowl and add the vinegar, stir and wait for it to curdle. Measure out all the dry ingredients into a large mixing bowl, and the oil into a separate bowl.
Step 3 – add the mashed sweet potato to the dry ingredients and mix everything together using the fork to get rid of any lumps
Step 4 – Add the curdled soy milk and oil and gently mix this should take no more than 15 folds. You want a batter that is lumpy.  The vinegar will react with the bicarb and the batter will have a spongy texture.
Step 5 – line a muffin pan with cases and divide the mixture equally between them. Sprinkle over some rolled oats before baking for 25 minutes.

Nutrition
Is for one large muffin (1/6 of the batter)
Batter
Should be lumpy - it will sort itself out as it cooks.  If you over mix the muffins will be tough and have tunnels in the dough.  You need to bake as soon as you mix the batter as the reaction between the vinegar and bicarb creates bubbles which makes for a lighter muffin.

These look lovely – a nice spiced muffin – what could be a better way to start a drab Sunday?
Arwen from Hoglet K
I haven’t tried eggless muffins, but the mashed sweet potato would be great for keeping them together. Spicy muffins with pockets of sugar sound lovely!
kathryn
Lovely recipe Helen. I really like the idea of spicy sweet potato mixed into the muffins. And that you’ve come up with a muffin formula that both works and gives you plenty of flexibility. Good one.

I love the idea of freshly baked homemade muffins for breakfast. A great simple recipe and really doable.

I’m so glad I have found a reliable muffin recipe. It seems the more I have tried, the more I have failed. I think my problem is over mixing, which I thought was a good idea.

I really like that these are vegan, as two of our family have now gone animal free. It can be quite difficult to find suitable ideas. These will go down a treat.
