Step 1: All You Will Need!
-large glass bowl
-13x9 oven pan
-large ziplock bag
-electronic mixer (preferably Kitchenaid)
Step 2: The Stuesel
-Place graham crackers in large ziplock bag and crush with rolling pin. (or with your hands)
-Melt margarine in glass mixing bowl. Microwave 1 minute or until fully melted.
-Add 2 cups crushed graham crackers to melted butter.
-Add 3/4 cups brown sugar (tightly packed in measuring cup) and stir until mixed.
-Add 1 1/4 teaspoon cinnamon.
Step 3: Cake Mix
-Add 1 cup water
-Add 1/4 cup oil
-Add 3 eggs
-Blend in mixer (I use the Kitchenaid but any electronic mixer will do.)
-blend 1 minute on low speed
-blend 2 minutes on medium speed
Step 4: Baking Time!
-Pour 1/2 of the cake mix in the pan and add 1/2 of the streusel. Repeat this step once again to make another layer.
-Place pan in over (middle rack) and bake at 350 degrees for 40-50 minutes. (yes, quite a broad time span, but it varies from ovens)
-(optional) test with toothpick by dipping it in and if it comes up clean, you're good to go.
-After the timer goes off, remove from pan with a hot pad .
Step 5: The Glorious Icing
Mix 1 cup powdered sugar with 1-2 tablespoons water
Drizzle when the cake has cooled.
You can make double the icing, but be warned, it gets quite sweet!
