What is Cinnamon Streusel Crumb Cake?

Cinnamon Streusel Crumb Cake is a tender yellow cake baked in a simple square pan and topped with a buttery crumb mixture made with brown sugar, granulated sugar, cinnamon, melted butter, and flour.

It has some of the same comforting flavor notes people love in coffee cake, but this version keeps things straightforward and classic. The cinnamon streusel brings warmth and sweetness without overwhelming the cake underneath, so every bite feels balanced. It’s cozy, familiar, and perfect for slow mornings, casual brunches, or an easy homemade treat to keep on the counter for a couple of days.

Substitutions & Additions

This recipe is wonderfully simple, but there are still a few easy ways to make it work with what you have on hand.

• Swap the milk: If needed, you can use another plain milk you already keep in the fridge. Just choose one with a neutral flavor so it doesn’t compete with the cinnamon.
• Add a little extra spice: If you want a slightly warmer flavor profile, a tiny pinch of nutmeg in the crumb topping could be nice. Keep it subtle so the cinnamon stays front and center.
• Try a glaze: If you want to dress it up a bit more for brunch, a light vanilla glaze over the cooled cake would work well.
• Serve with fruit: Fresh berries on the side can brighten up the rich, buttery flavors.

How to Make this Recipe

Start by preheating your oven to 350° F and spraying an 8 x 8 baking dish with non-stick cooking spray. Getting the dish ready first makes the rest of the process go quickly, and this is an easy recipe once everything is moving.

For the crumb topping, stir together 1/3 cup packed light brown sugar, 1/3 cup granulated sugar, and 1 teaspoon ground cinnamon in a medium bowl. Pour in 1/2 cup melted unsalted butter and stir until combined, then add 1 cup all-purpose flour. Mix until there are no dry streaks left. The mixture should look crumbly but evenly moistened. Set it aside while you make the batter.

For the cake, cream together 5 tablespoons softened unsalted butter and 1/2 cup granulated sugar until fluffy. This step helps give the cake its soft texture, so it’s worth taking an extra moment here. Mix in 1 large egg and 1 teaspoon vanilla extract, then slowly add 1/4 cup milk and mix until everything is incorporated.

Next, add 1 cup all-purpose flour, 3/4 teaspoon baking powder, 1/4 teaspoon baking soda, and 1/4 teaspoon salt. Mix until the batter is fully combined, scraping down the sides as needed so everything comes together evenly.

Spread the batter into the prepared baking dish, smoothing it into an even layer. Crumble the streusel topping over the batter so it’s evenly distributed across the top. Don’t pack it down too much—you want those natural little crumbles to stay in place so they bake up with texture.

Bake the Cinnamon Streusel Crumb Cake for about 30 to 35 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool completely before cutting into it. That cooling time helps the crumb topping settle and makes slicing much easier.

Cooking Tips & Tricks

• Use softened butter for the cake batter: It creams more smoothly with the sugar and gives you a better texture.
• Don’t overmix the batter: Once the dry ingredients go in, mix just until combined to keep the cake tender.
• Leave the crumb topping loose: A light, crumbly texture gives you the best finished topping.
• Check the cake at the 30-minute mark: Ovens can vary, so start checking then and bake a little longer if needed.
• Cool before slicing: It can be tempting to cut in early, but letting it cool helps the crumb topping stay put and keeps the cake from falling apart.

Serving Suggestions

This Cinnamon Streusel Crumb Cake is right at home beside a hot cup of coffee or tea, especially on cool mornings. It also works really well as part of a casual brunch spread with fresh fruit and eggs.

If you’re serving it for an afternoon treat, cut it into squares and plate it simply. The crumb topping already gives it plenty of character, so it doesn’t need much. For a slightly dressier presentation, you could dust the top lightly with powdered sugar right before serving.

Storage Suggestions

• Room Temperature: Store the cooled cake in an airtight container or tightly covered baking dish for up to 3 days.
• Refrigerator: For a little longer storage, refrigerate it for up to 1 week. Let it come closer to room temperature before serving for the best texture.
• Freezer: You can freeze individual slices or the whole cake once cooled. Wrap well and freeze for up to 3 months. Thaw before serving.
