First Step: Preheat your oven to 350°F and grease a 9 x 13 inch baking dish. This sets the stage for even baking and prevents the cake from sticking, so take a moment to prepare your dish for the banana crumb coffee cake batter.

Second Step: Make the crumb topping by crumbling ½ cup cold unsalted butter cubes with 1 cup all-purpose flour, 1 cup sugar, ½ cup brown sugar, and 1 teaspoon ground cinnamon until it forms a crumbly mixture. Set this aside, as this crunchy topping will add that signature texture to your banana cake later.

Third Step: In a large bowl, whisk together 2 cups all-purpose flour, 3 teaspoons baking powder, 1 teaspoon ground cinnamon, and 1 teaspoon salt. This dry mix forms the foundation of your moist coffee cake, ensuring it rises properly and has great flavor.

Fourth Step: In a stand mixer, cream ½ cup softened butter until it’s creamy, then add 1 cup sugar and mix well. For dietary adaptations, if you’re using vegan butter, this step keeps the same creamy result while making the recipe inclusive.

Fifth Step: Add 2 eggs, 1 teaspoon vanilla extract, and 3 mashed ripe bananas to the mixer, blending just until combined. The bananas bring natural moisture to your banana crumb coffee cake, so use overripe ones for the best taste and texture.

Sixth Step: Alternate mixing in the flour mixture and 1 cup almond milk until everything is combined. This creates a smooth batter for your coffee cake, and you can swap the milk for other options if needed to suit various preferences.

Seventh Step: Pour half the batter into your prepared baking dish, then sprinkle one-third to one-quarter of the crumb topping evenly over it. This layering technique ensures the crunchy topping integrates perfectly into the moist layers of your banana cake.

Eighth Step: Add the remaining batter on top, followed by the rest of the crumbs. For variations, you could adjust the amounts to make a thicker crunchy topping on your banana crumb coffee cake.

Ninth Step: Bake for 50 55 minutes, or until a toothpick inserted in the center comes out clean. Keep an eye on the time to achieve that ideal moist texture without overcooking, and remember to adapt baking for different ovens if necessary.

Tenth Step: If using the optional glaze, mix 1 cup powdered sugar with 1 2 tablespoons milk until it’s smooth, then drizzle over the cake after it cools slightly. This final touch enhances the flavor of your banana coffee cake and can be skipped for a simpler finish.

Eleventh Step: Let the cake cool for 5 10 minutes before serving. This allows the flavors to settle, making your banana crumb coffee cake even more enjoyable, whether you’re pairing it with coffee or serving it as a dessert.
