GLAZE FOR COFFEE CAKE RECIPES

Steps:

• Preheat the oven to 350 degrees F. Lightly grease a 13 by 9-inch glass baking dish with 2 teaspoons of the butter.
• In a large bowl, cream together the remaining stick of butter and sugar until light and fluffy. Add the eggs 1 at a time, beating after the addition of each. In a separate bowl or on a piece of parchment, sift together the flour, baking soda, cinnamon, and salt. Add to the wet ingredients, alternating with the sour cream and vanilla. Fold in the apples. Pour into the prepared baking dish, spreading out to the edges.
• To make the topping, in a bowl, combine the sugar, flour, cinnamon, and butter, and mix until it resembles coarse crumbs. Sprinkle the topping over the cake and bake until golden brown and set, 35 to 40 minutes. Remove from the oven and let cool on a wire rack for at least 10 minutes.
• To make the glaze, in a bowl, combine the sugar, vanilla, and water and mix until smooth. Drizzle the cake with the glaze and let harden slightly. Serve warm.

Steps:

• Preheat the oven to 350 degrees F. Grease and flour a 10-inch tube pan.
• Cream the butter and sugar in the bowl of an electric mixer fitted with the paddle attachment for 4 to 5 minutes, until light. Add the eggs 1 at a time, then add the vanilla and sour cream. In a separate bowl, sift together the flour, baking powder, baking soda, and salt. With the mixer on low, add the flour mixture to the batter until just combined. Finish stirring with a spatula to be sure the batter is completely mixed.
• For the streusel, place the brown sugar, flour, cinnamon, salt, and butter in a bowl and pinch together with your fingers until it forms a crumble. Mix in the walnuts, if desired.
• Spoon half the batter into the pan and spread it out with a knife. Sprinkle with 3/4 cup streusel. Spoon the rest of the batter in the pan, spread it out, and scatter the remaining streusel on top. Bake for 50 to 60 minutes, until a cake tester comes out clean.
• Let cool on a wire rack for at least 30 minutes. Carefully transfer the cake, streusel side up, onto a serving plate. Whisk the confectioners' sugar and maple syrup together, adding a few drops of water if necessary, to make the glaze runny. Drizzle as much as you like over the cake with a fork or spoon.
