I love cake (can you tell?) and, as much as I have a passion for cake, I also love apple crumble. What is better than combining all the things you love into one and getting maximum enjoyment? 

Please remember though that you can be so flexible with this recipe, like with all of my recipes. So if you want to remove the apple and cinnamon and replace this with another fruit or maybe even chocolate or coffee flavoured muffins; get creative! Just bear in mind to make sure that the fruit alternative isn’t too wet or if you add cocoa for a chocolate muffin to  add a few tablespoons of milk/minus out a few tablespoons of flour. 

What makes this recipe so delicious is the sour cream which keeps the muffin moist AND you will have enough for the week to enjoy with your hot beverage (tea, coffee, chai latte). You will also save yourself a little rather than popping to the cafe for your caffeine/sweet fix.
