To begin making the Coffee Raisin Cake With Sugar Glaze recipe, sift together the flour, baking powder, and salt in a bowl. Kep it aside. 

In a separate bowl, using electric beater, cream the butter and white sugar.

In a small bowl, take 2 teaspoons of instant coffee and add in a teaspoon of warm water. Mix and add it to the creamed butter.

Beat for few more seconds. In the creamed butter, add the sifted flour and the milk in alternate batches, mixing until just combined after each addition.

Take the egg whites in a separate bowl and with beater, beat them on high till you get stiff peaks. Pour this beaten egg whites into the prepared flour batter and fold gently.

Once it is done, pour the batter into a greased 9 x 13 baking pan for the coffee raisin cake. Spread evenly.

In a bowl, add in ingredients mentioned for topping and mix with fork or hands. It will be a sticky mixture.

Add it all over the poured cake batter. Now pop the pan into the oven and bake for 40 to 45 minutes at 350 degree Farenheit. (Don't worry if the batter is poufing and becoming all buttery and sugary, it is normal)

Once the Coffee Raisin Cake With Sugar Glaze, remove out and keep on the cooling rack. Once it cools down, flip it on a tray. Turn over, so that the topping crumbly side faces up.

The next step is to make the glaze. Take powdered sugar in a bowl and add a teaspoon of water at a time. Keep mixing until you get nice thick syrup.

Drizzle over nicely cooled cake. Cut the cake into desired pieces and enjoy. Serve Coffee Raisin Cake for your tea break along with a cup of Espresso Coffee and Linzer cookies.
