Method (streusel)

1. In a medium-sized bowl, stir together the flour, sugar and lemon zest.
2. Add in the room temperature butter and use a fork to mix and claw the ingredients together until combined but still clumpy. Don’t over-mix or the streusel will become like a soft paste, simply toss together until mixture is clumpy, no longer dry, and the flour is completely combined. Set aside while you make the muffin mixture. Make the streusel the day before and store in the fridge in a sealed container.

Method (lemon muffins)

1. Preheat the oven to 180°C fan and line two 6 cup cupcake tins with cupcake / muffin liners.
2. In a small bowl combine the flaxseed with the water, stir until a paste and set aside. This will turn thick and jelly like.
3. In a medium sized mixing bowl, sieve in the flour, baking powder, arrowroot, xanthan gum and sugar. Mix to break up any lumps.
4. In a separate bowl, add in the yogurt, room temperature butter, milk, lemon juice and lemon zest. Mix to combine. Pour the wet into the dry and mix until just incorporated. Don’t over-mix!
5. Using an ice-cream scoop or spoon, divide the mixture between the cases. Make sure the batter reaches the top of the liners.
6. Sprinkle a good amount of the streusel on top of each muffin, making sure the tops are covered.
7. Place into the middle of the oven and bake for 12 minutes at 180°C fan. After 12 minutes, reduce the oven temperature to 160°C fan and bake for a further 16-18 minutes, or until the skewer / toothpick inserted into the middle of the muffins come out clean. 
8. Remove from the oven and allow the muffins to cool in the tin.

Method (lemon curd)

1. In a small bowl, add in the corn flour and water. Stir together into thick paste.
2. Add the cornflour paste, dairy-free butter, sugar, lemon juice, lemon zest, condensed milk and a pinch of turmeric into a medium sized saucepan.
3. Place the saucepan on the hob and heat over low to medium, stirring constantly, preferably with a whisk. After around 5-8 minutes the lemon curd will thicken. If the curd isn’t thickening, turn up the heat and constantly whisk.
4. Pour curd into a heat proof jar or bowl, cover and place aside to cool down.
5. You can either put it in the fridge or keep it at room temperature to cool. Before you use it, give it a good stir as it will thicken.

Method (icing)

1. In a small bowl, add in the icing sugar. Add a teaspoon of lemon juice in at a time, stirring in-between until you have a smooth and runny paste. Drizzle over as much as you want over the tops of the muffins.
2. Serve and enjoy!
