Grandma Betty's coffee cake recipe is a classic and delicious treat that is perfect for breakfast or brunch. The combination of moist cake with a sweet, nutty streusel topping is sure to comfort and satisfy!
Preheat the oven to 350ºF. Cover a baking sheet with parchment paper.
Add the 1 cup flour, 1 tablespoon water, and ½ cup butter to a large mixing bowl. Use an electric mixer to mix consistently until combined and begins to crumble together, like wet sand. Using your hands, press the dough together to form a ball.
Separate the mixture into two balls and place them on a baking sheet. Gently form each ball into a long, flat, loaf-like shape. Set aside. The loaves should be about 10x2-inches and about ½ inches thick.
Next, add 1 cup water, 1 cup flour, 3 eggs, ½ teaspoon almond extract, and ½ cup butter to a saucepan. Stir and heat the mixture over medium/high heat to a boil.
Remove the pan from heat to beat the mixture with a wooden spoon to make a firm ball. This will take around 5 minutes.
Spread the mixture evenly over the coffee cake loaves on the baking sheet.
Bake until golden brown, about 30-40 minutes, depending on the oven.
While the coffee cake is baking, prepare the frosting. Mix the powdered sugar, butter, almond extract, and warm water. Mix until smooth. Note that it is more of a glaze rather than a thick frosting.
Remove the coffee cake from the oven and let the cake completely cool before frosting.
Serve immediately or store when cool in an air-tight container.

Notes
Be sure the loaves are long and thin enough, or you will end up with lumps.
In step #4, we are making a pâte à choux. It is a pastry Choux pastry that is made with butter, water, flour, and eggs. Instead of a raising agent, choux pastry employs its high moisture content to create steam, as the water in the dough evaporates when baked, puffing the pastry.
