In another large bowl, make muffin mixture of flour, sugar, baking soda, and salt until combined. Add the 6 tbsp of coconut oil, 1 tbsp at a time. Add the egg, yolk, vanilla, and buttermilk and mix until all has been incorporated and is light and fluffy. Measure out 1/4 c of batter and place into muffin tins. Sprinkle a generous amount of crumb topping on top. Bake for 20 min or until crumbs are golden and toothpick comes out clean.
