Preheat your oven to 350*F and grease a 10 inch springform pan, cake pan, or bundt cake pan. Whichever you choose. I like to use a springform pan just because it ensures the cake will come out easily

In a bowl cream together with an electric mixer the butter and sugar until smooth

Add the eggs, vanilla, and sour cream. Mix until smooth

To the wet ingredients add the flour, baking powder, baking soda, and salt. Mix all together until just combined and smooth. Put that to the side and make the streusel

In a small bowl combine the brown sugar, flour, cinnamon, and salt. Add the cold butter and with your fingers and pinch the mixture until it forms a crumble

Add half the batter to the pan and even out with a spatula. To the top of the batter add about 3/4 of the streusel in an even layer

Put the remaining half of the batter and once again spread it out evenly. Add the rest of the streusel to the top of the batter and put in the oven

Let cook for one hour or until you stick a knife in the middle and it comes out clean

Take out of the oven and let cool slightly

When it is cooled take out of the pan and put the cake streusel side up on the cake plate you are going to use. Now it’s time to make the glaze

In a small bowl add the powdered sugar and maple syrup. Sitr until the glaze is all mixed together. You might need a little more maple syrup in order to make it runny

Drizzle the glaze with a fork or spoon as you’d like. Slice, and serve! Who says you can’t eat dessert for breakfast?
