Baking this Banana Crumb Coffee Cake is all about layering a velvety banana batter with a sweet, spiced crumb topping for the ultimate breakfast delight. Follow these simple steps to blend your ingredients just right, achieve that irresistible crumb, and bake to golden perfection.
1. Preheat the oven to 350°F (175°C) and grease an 8-inch square baking pan with butter or nonstick spray for easy release.
2. In a large bowl whisk together 1 1/2 cups all-purpose flour, 1 cup granulated sugar, 2 teaspoons baking powder, 1/2 teaspoon baking soda, and 1/2 teaspoon salt until evenly combined.
3. In another bowl combine 2 medium mashed bananas, 1 large egg, 1/2 cup milk, 1 teaspoon vanilla extract, and 1/4 cup melted unsalted butter, stirring until the mixture is smooth and homogenous.
4. Pour the wet ingredients into the dry ingredients and stir just until combined—be careful not to overmix or the cake may become dense.
5. Spread the batter evenly into the prepared pan, smoothing the top with a spatula for a level bake.
6. In a small bowl mix 1/2 cup all-purpose flour, 1/2 cup packed brown sugar, and 1 teaspoon ground cinnamon; then cut in 3 tablespoons cold diced unsalted butter with your fingers or a pastry cutter until coarse, pea-sized crumbs form.
7. Sprinkle the crumb topping evenly over the banana batter, covering the surface completely for that signature crunch.
8. Bake for 30 to 35 minutes, or until the edges are lightly golden and a toothpick inserted into the center comes out clean or with a few moist crumbs attached.
9. Let cool in the pan on a wire rack for at least 15 minutes before slicing and serving to set the crumb layer and make clean cuts.

Here are answers to common questions to help you bake with confidence:
A: Preparing the batter and crumb topping takes about 15 minutes, including mashing ripe bananas, measuring ingredients, and mixing. Baking requires 30 to 35 minutes in a preheated 350°F (175°C) oven, and you should allow an additional 15 minutes for the cake to cool in the pan before slicing and serving.
A: The cake is fully baked when the edges turn a light golden brown and a toothpick inserted into the center comes out clean or with just a few moist crumbs attached. Avoid opening the oven too early to ensure the cake rises properly before checking for doneness.
A: You can use a dairy-free milk substitute, such as almond or oat milk, in place of regular milk, and melted coconut oil can replace the unsalted butter if you prefer. If you need a gluten-free version, swap the all-purpose flour for a 1:1 gluten-free baking blend. Keep all other proportions the same and monitor baking time closely when using alternative flours.
A: To prevent the crumbs from sinking, make sure the batter is spread evenly and not too thin. Cut the cold butter into the crumb mixture until it forms coarse, pea-sized pieces. Gently sprinkle the crumbs over the top without pressing them down, which helps them stay on the surface and bake into a distinct layer.
A: Once completely cooled, place leftover slices in an airtight container at room temperature for up to two days. To enjoy a warm slice, microwave an individual piece for 10 to 15 seconds. For longer storage, wrap slices tightly in plastic wrap, then foil, and freeze for up to two months, thawing overnight in the refrigerator before reheating.
A: Yes. For added crunch and flavor, stir a handful of chopped nuts such as walnuts or pecans into the crumb topping before sprinkling it on the batter. You can also fold in a teaspoon of ground nutmeg or a pinch of cloves with the cinnamon for a spicier profile, or swirl in a tablespoon of cream cheese into the batter for extra richness.
