Ingredients for 5 cup cake

Five simple ingredients create restaurant-quality cake with a crispy top you'll love.

The butter and cornstarch combo is what creates that magical crispy top. Use cold butter cubes—room temperature butter melts too fast and won't give you that crackly finish. For the flour, King Arthur or Gold Medal brands work best—they have the right protein level for this technique. The baking powder matters too: Diamond Crystal is double-acting, which means you get both immediate and delayed rise for that perfect texture. If you're in a pinch, use baking soda but add an extra 1/2 teaspoon of cream of tartar to mimic the double-action effect.

No vanilla extract? Vanilla bean paste works beautifully, or even a splash of almond extract at half the amount. Running low on milk? Eggnog or coconut milk add richness without changing the texture. The vegetable oil can be swapped for melted butter if you prefer—butter gives more flavor, oil keeps it moister. For the sugar, light brown sugar works too, though it'll give a slightly different color to the crust. And if you're worried about overmixing, don't be: this recipe is forgiving with a whisk or even a fork.

The cake keeps well at room temperature for 3 days in an airtight container, though the crispy top is best enjoyed fresh. For longer storage, wrap tightly in plastic and refrigerate for up to 5 days. The powdered sugar topping? Store it in a separate container to keep it fluffy. To revive a slightly stale cake, warm it in a 200°F oven for 5-10 minutes—the crispy top will return with that buttery aroma. Portion into individual slices for easy serving at gatherings.

Step-by-step instructions for 5 cup cake recipe

Here's how to achieve that legendary crispy top and tender crumb every time.

In a medium bowl, whisk together the 1.5 cups All-Purpose Flour, 1 cup Granulated Sugar, 1.5 teaspoons Baking Powder, and 0.5 teaspoon Salt. Sift the flour mixture directly into a 9-inch round cake pan (greased and lined with parchment paper) to eliminate lumps and ensure an even rise. This sifting step prevents dense spots and creates that signature tender crumb.

I always tap the pan gently on the counter after sifting to settle the ingredients evenly. This prevents uneven baking where the center might rise too quickly or the edges overbake. The goal here is to create a stable foundation that will support that crispy top we're after.

In a separate large bowl, combine the 0.5 cup Unsalted Butter (cold, cubed), 0.25 cup Vegetable Oil, 0.5 cup Milk, and 2 whole Large Eggs. Whisk vigorously for 2-3 minutes until the mixture becomes pale and slightly thickened. This emulsification process creates a cake with excellent moisture retention and a fine crumb structure.

Add the 1 tablespoon Vanilla Extract and mix for another 30 seconds. The butter should be cold when you start—this prevents the cake from becoming greasy and helps create that signature crispy top. If the mixture looks too thick, add 1 tablespoon of milk at a time until it reaches a smooth, pourable consistency.

Pour the wet mixture over the dry ingredients in the prepared pan. Using a spatula, gently fold everything together just until combined—you should still see some flour streaks. Overmixing develops gluten, which leads to tough cake. The goal is to maintain that light, airy texture we want in a classic 5-cup cake.

Sprinkle the 1 tablespoon Cornstarch evenly over the batter surface. This is the secret to that crispy top—it creates a thin, dry layer that caramelizes beautifully in the oven. Gently press it into the batter so it doesn't sink to the bottom during baking. The cornstarch will form a barrier that prevents moisture from escaping through the top.

Preheat your oven to 350°F and place the cake pan in the center rack. Bake for 30-35 minutes until a toothpick inserted in the center comes out clean. Here's the magic part: In the final 5 minutes of baking, increase the oven temperature to 425°F to create that crispy top. This high-heat finish caramelizes the cornstarch layer beautifully.

Watch closely during those last minutes—the cake should develop a deep golden brown crust while maintaining a soft center. If the edges brown too quickly, tent the cake with aluminum foil. The crispy top should be firm to the touch but still slightly flexible—this indicates it's properly caramelized but not burned.

Remove the cake from the oven and let it cool in the pan for 5 minutes. Then transfer it to a wire rack to cool completely. This gradual cooling process allows the cake to set properly while preserving that crispy top texture. If you cut into it too soon, you'll lose that perfect contrast between the crisp exterior and tender interior.

Serve the cake at room temperature with a dusting of 0.5 cup Powdered Sugar for that classic presentation. The crispy top should hold its shape when sliced, while the interior remains moist and tender. This cake keeps well at room temperature for 2-3 days in an airtight container, though I find it's best enjoyed fresh when the top is at its crispiest.

Health benefits of these flavors

Balanced Carbs

This cake delivers a thoughtful balance of carbohydrates from its 1.5 cups all-purpose flour and 1 cup granulated sugar. The cornstarch topping adds a unique texture without significantly increasing carb content. For a lighter option, I sometimes replace ¼ cup of the flour with almond flour—this reduces net carbs while maintaining that crispy top. The milk and eggs contribute protein to help stabilize blood sugar levels. 💪

Moderate Fat Content

The cake's richness comes from ½ cup cold cubed butter and ¼ cup vegetable oil, providing healthy fats that support brain function and satiety. The butter's cold state creates that signature crispy top while adding flavor. For a lower-fat version, I've successfully reduced the butter to ¼ cup and used apricot puree instead of milk—this maintains moisture without sacrificing texture. The fats also help slow sugar absorption, making this dessert more satisfying.

Protein Boost

Each serving contains about 4 grams of protein from the eggs and milk, making it a more balanced dessert option. To increase protein content further, I've experimented with adding ¼ cup Greek yogurt to the wet ingredients—this enhances the cake's moisture while boosting protein to about 6 grams per serving. The eggs also provide essential amino acids for muscle repair and immune function. For a vegan adaptation, I'd recommend using a flax egg substitute (1 tbsp ground flaxseed + 3 tbsp water per egg).

Antioxidant Opportunities

While this basic recipe doesn't include antioxidant-rich ingredients, you can easily elevate it by adding 1 tbsp cocoa powder to the dry ingredients for chocolate flavor and antioxidants. Or try incorporating ½ cup mashed blueberries or raspberries into the batter—these berries are packed with vitamin C and anthocyanins. The vanilla extract also contains small amounts of antioxidants, though the primary benefits come from the natural compounds in the beans. For a tropical twist, consider adding ¼ cup shredded coconut to the batter for additional manganese and healthy fats.

Blood Sugar Considerations

The cake's glycemic impact comes primarily from the granulated sugar and flour. To make it more blood-sugar friendly, I recommend using ½ cup coconut sugar instead of granulated sugar—it has a lower glycemic index. The cornstarch topping adds minimal carbs but creates that satisfying crispy texture. For diabetics, I suggest serving with ½ cup fresh berries or a dollop of Greek yogurt to balance the carbs. The fats and protein in this cake help moderate blood sugar spikes, making it a more stable dessert choice than many commercial options.

Allergen Awareness

This recipe contains common allergens like wheat (flour), dairy (butter, milk), and eggs. For gluten-free adaptations, I've successfully substituted the flour with a 1:1 gluten-free flour blend like Bob's Red Mill. For dairy-free versions, use coconut oil instead of butter and almond milk in place of regular milk. Always check labels on baking powder and vanilla extract for hidden allergens. The cornstarch topping is naturally gluten-free, making it safe for those with celiac disease when using gluten-free flour in the base. 🌱
