Turmeric and Blueberry Breakfast Muffins

This recipe can very easily be altered, so I have gathered some recipe notes:
• One or two grated carrots can be a delicious addition.
• The granola crumble is optional (although very delicious) and can be left out.
• If you don’t have any problems with gluten, the buckwheat flour+arrowroot can be replaced with an equal amount of spelt flour.
• The eggs can be replaced with chia seeds or flax seeds following the ratio 1 tbsp chia/flax + 3 tbsp water = 1 egg.
• The blueberries can obviously be replaced with other berries. Blackberries would be good.
• If you don’t like or am allergic to walnuts, you can replace them with sunflower seeds.
• The dates can be replaced with 3-4 tbsp honey. You can also add a little honey along with the dates if you prefer a sweeter muffin.
