Name: The Best Apple Coffee Cake with Cinnamon Streusel Topping Recipe
Ingredients: 1 ½ cups All-Purpose Flour: The foundation of our cake, all-purpose flour provides the structure. Its protein content develops gluten, which gives the cake its tender crumb. For best results, use good quality all-purpose flour. If you prefer, you can substitute with ¾ cup all-purpose flour and ¾ cup cake flour for an even more tender crumb, but all-purpose alone works beautifully.; 1 teaspoon Baking Powder: This is a chemical leavening agent that creates air bubbles in the batter, making the cake rise and become light and fluffy. Ensure your baking powder is fresh (check the expiration date) for optimal leavening.; ½ teaspoon Baking Soda: Another leavening agent, baking soda reacts with acidic ingredients like sour cream in this recipe, contributing to the cake’s rise and tender texture. Like baking powder, freshness is key.; ½ teaspoon Salt: Salt enhances the flavors of all the other ingredients in the cake, especially the sweetness and spices. It also balances the overall flavor profile, preventing the cake from being overly sweet. Use fine sea salt or table salt.; ½ teaspoon Ground Cinnamon: The warm, aromatic spice that’s synonymous with apple desserts. Cinnamon adds depth and complexity to the cake, complementing the apples beautifully. For a richer flavor, consider using Ceylon cinnamon or freshly ground cinnamon if you have the option.; ¼ teaspoon Ground Nutmeg: Nutmeg adds a subtle warmth and spice that rounds out the cinnamon flavor. A little goes a long way, so ¼ teaspoon is perfect. Freshly grated nutmeg is even more fragrant and flavorful, if you’re feeling ambitious.; ½ cup Unsalted Butter, Softened: Butter is crucial for moisture, flavor, and richness in the cake. Using unsalted butter allows you to control the salt content precisely. Make sure the butter is softened to room temperature (but not melted) for proper creaming with sugar, which is essential for a light and airy cake.; ¾ cup Granulated Sugar: Sugar not only sweetens the cake but also contributes to its moisture and tenderness. Granulated sugar creams well with butter, creating air pockets that contribute to the cake’s texture.; 2 Large Eggs: Eggs provide structure, richness, and moisture to the cake. They also emulsify the wet and dry ingredients. Use large eggs at room temperature for better incorporation into the batter.; 1 teaspoon Vanilla Extract: Vanilla extract enhances the overall flavor profile, adding a touch of warmth and sweetness. Use pure vanilla extract for the best flavor. You could also experiment with vanilla bean paste for an even more intense vanilla flavor.; ½ cup Sour Cream: Sour cream adds moisture and tenderness to the cake, and its acidity reacts with baking soda to create a lighter texture. It also adds a subtle tang that complements the sweetness. Full-fat sour cream is recommended for the best flavor and texture. You can substitute with plain Greek yogurt for a slightly tangier result.; 1 ½ cups Peeled and Finely Diced Apples, about 2 medium apples: The star of the show! Apples provide moisture, sweetness, and a delightful texture to the cake. Choose apple varieties that hold their shape well when baked and have a good balance of sweetness and tartness. Good options include Honeycrisp, Fuji, Gala, or Braeburn. Finely dicing the apples ensures they distribute evenly throughout the cake and cook through properly.; ½ cup All-Purpose Flour: Similar to the cake, flour provides structure to the streusel, creating those delightful crumbs.; ½ cup Light Brown Sugar, Packed: Brown sugar adds sweetness, moisture, and a hint of molasses flavor to the streusel. Packing it ensures you have the correct amount and contributes to the streusel’s clumpy, crumbly texture. Light brown sugar is preferred for its milder molasses flavor, but you can use dark brown sugar for a richer taste.; 1 teaspoon Ground Cinnamon: Cinnamon is essential in the streusel, enhancing the warm spice notes and complementing the apple cake.; ¼ cup Unsalted Butter, Melted: Melted butter binds the dry ingredients together, creating the crumbly texture of the streusel. Using melted butter ensures the streusel is easy to sprinkle and bake evenly.

Instructions

1. Preheat and Prepare:

Begin by preheating your oven to 350°F (175°C). This ensures the oven is at the correct temperature when you place the cake in, promoting even baking.

Grease a 9×9-inch square baking pan thoroughly with butter or cooking spray. Alternatively, for easier removal, line the pan with parchment paper, leaving an overhang on the sides to lift the baked cake out. This step is crucial to prevent the cake from sticking to the pan.

2. Prepare the Cake Batter:

Combine Dry Ingredients: In a medium-sized mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, ground cinnamon, and ground nutmeg. Whisking ensures the dry ingredients are evenly distributed and any clumps are broken up. This step is important for consistent leavening and flavor throughout the cake. Set aside this bowl of dry ingredients.

Cream Butter and Sugar: In a large mixing bowl (or the bowl of a stand mixer), cream together the softened unsalted butter and granulated sugar. Beat on medium speed until the mixture is light and fluffy. This process incorporates air into the butter and sugar, which is essential for a tender and airy cake. It should take about 2-3 minutes of beating.

Incorporate Eggs and Vanilla: Add the large eggs one at a time to the creamed butter and sugar mixture, mixing well after each addition. This ensures each egg is fully incorporated and contributes to the emulsion. Stir in the vanilla extract. Mix until just combined.

Alternate Wet and Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, alternating with the sour cream. Begin and end with the dry ingredients. This means you’ll add about a third of the dry ingredients, mix until just combined, then add half of the sour cream, mix, then another third of the dry ingredients, mix, the remaining sour cream, mix, and finally the last third of the dry ingredients, mixing until just combined. Mix until just combined. Overmixing can develop gluten and result in a tough cake.

Fold in Apples: Gently fold in the finely diced apples into the batter using a spatula. Distribute them evenly throughout the batter. The batter will be thick, which is normal due to the sour cream and the amount of fruit.

3. Make the Cinnamon Streusel Crumb Topping:

Combine Streusel Ingredients: In a small mixing bowl, combine the all-purpose flour, light brown sugar, and ground cinnamon for the streusel. Stir them together to remove any lumps.

Add Melted Butter: Pour the melted unsalted butter into the dry streusel mixture. Stir with a fork or your fingers until the mixture resembles coarse crumbs. The mixture should be moist and clumpy but not wet or pasty. If it seems too dry, add a tiny bit more melted butter, a teaspoon at a time.

4. Assemble the Cake:

Spread Batter in Pan: Pour the prepared cake batter evenly into the greased or parchment-lined 9×9-inch baking pan. Use a spatula to spread it to the corners and level the surface.

Sprinkle Streusel Topping: Sprinkle the cinnamon streusel crumb topping evenly over the cake batter. Ensure it covers the surface for a beautiful and crunchy topping in every bite.

5. Bake:

Bake in Preheated Oven: Place the baking pan in the preheated oven and bake for 35-40 minutes. The baking time can vary slightly depending on your oven, so it’s important to check for doneness.

Check for Doneness: To check if the cake is done, insert a wooden toothpick into the center of the cake. If the toothpick comes out clean or with only a few moist crumbs attached (but no wet batter), the cake is done. The top should be golden brown, and the edges should be pulling away slightly from the sides of the pan. If the toothpick comes out with wet batter, bake for a few more minutes and check again.

6. Prepare the Optional Cream Cheese Cinnamon Glaze (While Baking):

Combine Glaze Ingredients: While the cake is baking, prepare the glaze. In a small bowl, whisk together the softened cream cheese, powdered sugar, vanilla extract, and ground cinnamon until smooth and creamy. Ensure the cream cheese is softened to avoid lumps in the glaze.

Adjust Consistency with Milk: Gradually add milk, one tablespoon at a time, to the glaze, whisking well after each addition, until the glaze reaches a thin, drizzling consistency. You want it to be pourable but not too runny. You might need 2-3 tablespoons of milk, or slightly more, to achieve the perfect consistency.

7. Finish and Serve:

Cool Slightly: Once the cake is baked, remove it from the oven and allow it to cool in the pan for about 10 minutes. This allows the cake to set slightly before glazing.

Drizzle Glaze: If using, drizzle the cream cheese cinnamon glaze evenly over the slightly warm cake. The glaze will melt slightly and set beautifully as the cake cools further.

Serve and Enjoy: Cut the Apple Coffee Cake into 9 squares. Serve warm or at room temperature. It’s delicious on its own or with a scoop of vanilla ice cream or a dollop of whipped cream.
