This 2-cup flour cake recipe delivers the perfect balance of lightness and richness in a single-bowl wonder that’s foolproof for beginners and satisfying for seasoned bakers. The secret lies in the vanilla infusion—extract, not imitation—paired with precise measurements that prevent dryness while keeping the texture tender and moist. I’ve tested this recipe countless times, and it never fails to produce a cake with a golden crust and a crumb so fine it practically melts in your mouth.

The beauty of this recipe is its simplicity: no fancy equipment, no complicated steps, and just five core ingredients (plus a few pantry staples). The method is a streamlined one-bowl approach, where you cream butter and sugar, alternate dry and wet ingredients, and let the vanilla work its magic. No electric mixer? No problem—this cake comes together just as well with a sturdy wooden spoon. The result is a cake that’s light enough to eat plain but rich enough to handle frosting, glaze, or fresh berries.

What sets this cake apart is its versatility—bake it for a casual weekend brunch, layer it for a celebration, or serve it warm with a dusting of powdered sugar. The vanilla flavor shines without overpowering, making it a blank canvas for fillings like lemon curd, chocolate ganache, or even a simple whipped cream. And because it’s baked in a standard 9-inch pan, it’s the perfect size for sharing (or not).

Ingredients for 2 cup flour cake

Five core ingredients plus pantry staples—this single-bowl cake delivers restaurant-quality vanilla flavor every time.

The vanilla extract is non-negotiable here—real vanilla, not imitation. McCormick or Nielsen-Massey are my go-tos, but any pure extract works. For the butter, Land O’Lakes or Plugrá are reliable brands, but any unsalted butter will do—just make sure it’s softened to room temperature (press your finger in; it should leave a slight indent). The flour? King Arthur or Gold Medal are my favorites, but any all-purpose will work. Sift it before measuring for that perfect light texture. And don’t skip the brown sugar—it adds that subtle caramel depth that makes this cake stand out.

No vanilla extract? Vanilla bean paste at double the amount works in a pinch, though the flavor won’t be identical. Short on milk? Heavy cream or buttermilk adds richness, but whole milk is the safest swap. No vegetable oil? Melted butter or coconut oil can replace it, but reduce other fats slightly to balance. For the eggs, if you’re avoiding them, a flax egg (1 tbsp ground flax + 3 tbsp water per egg) keeps the texture intact. And if you’re baking at high altitude, add an extra 1/4 tsp baking powder—this cake is forgiving but loves a little extra lift when needed.

Store leftovers in an airtight container at room temperature for up to 3 days, or in the fridge for 5 days. For longer storage, wrap tightly in plastic and freeze for up to 3 months. The cake reheats beautifully—just pop slices in the oven at 300°F for 5-10 minutes to restore freshness. And here’s a pro tip: Bake an extra half-pan if you’re feeding a crowd. This cake freezes like a dream and thaws perfectly, making it the ultimate make-ahead dessert.

Step-by-step instructions for single-bowl vanilla cake

This cake comes together in one bowl with minimal effort but maximum flavor—here’s how to make it perfectly every time.

In a large mixing bowl, combine the 1 cup unsalted butter and 1.5 cups granulated sugar. Using an electric mixer on medium speed, beat for 3-4 minutes until the mixture is light, pale yellow, and nearly doubled in volume. This creaming process incorporates air, which creates that signature tender crumb we’re after.

Here’s the thing—don’t rush this step. You’ll know it’s ready when you lift the beaters and the mixture holds soft peaks. If you’re using cold butter, you might need an extra minute or two to fully soften it. The butter should be smooth and completely homogeneous with no visible streaks of sugar.

Add the 2 whole large eggs one at a time, mixing well after each addition on low speed. Then add the 2 teaspoons pure vanilla extract and mix just until combined. The mixture might look slightly curdled after adding the eggs, but that’s completely normal and will resolve itself when we add the dry ingredients.

I always use room-temperature eggs for this recipe because they blend more smoothly and create a lighter texture. If your eggs are straight from the fridge, let them sit in warm water for 5 minutes before adding them. The vanilla extract should be pure—imitation vanilla lacks the depth of flavor that makes this cake truly special.

In a separate small bowl, whisk together the 2 cups all-purpose flour, 1.5 teaspoons baking powder, and 0.5 teaspoon salt. With the mixer on low speed, gradually add about one-third of the flour mixture to the wet ingredients, mixing just until incorporated. Then add half of the 0.5 cup milk and mix until combined.

Repeat this process, alternating between the remaining flour mixture and the remaining milk, ending with the last of the flour mixture. The key here is to mix just until combined—overmixing develops gluten and makes the cake tough. You should still see some small flour streaks in the batter, which is exactly what we want for that tender crumb.

Add the 0.25 cup vegetable oil to the batter and mix on low speed until completely incorporated. The oil helps create a moist, tender cake. Mix for about 30 seconds or until the batter is smooth and no streaks remain. At this point, the batter should be thick but pourable—similar to heavy pudding.

Real talk: The batter might look curdled or slightly lumpy at this stage, but don’t worry. Once it bakes, those imperfections will disappear, leaving you with a perfectly smooth interior. Give the batter one final stir by hand to ensure everything is evenly distributed before pouring into your prepared pan.

Pour the batter into a 9-inch round cake pan lined with parchment paper or greased with butter. Bake in a preheated 350°F oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean and the top is golden brown. The cake should spring back slightly when pressed gently in the center.

Don’t open the oven during the first 20 minutes of baking—this helps maintain even heat distribution and prevents the cake from sinking in the middle. If the edges are browning too quickly, tent the cake loosely with aluminum foil to protect them while allowing the center to continue baking.

Dietary considerations for this 2 cup flour cake

Gluten-Free Swaps

For a gluten-free version, replace the 2 cups all-purpose flour with a 1:1 gluten-free flour blend like Bob’s Red Mill 1-to-1 or King Arthur Measure for Measure. Add ½ teaspoon xanthan gum to help bind the crumb. Keep all other ingredients the same, but expect a slightly denser texture—this cake still comes out moist and delicious. 🌾

Dairy-Free Adaptations

Swap the 1 cup butter for 1 cup dairy-free butter (like Miyoko’s or Earth Balance), and replace the ½ cup milk with ½ cup unsweetened almond milk or oat milk. The vegetable oil stays the same, ensuring moisture. The cake will be just as tender, though slightly less rich. Test with a toothpick for doneness—dairy-free versions may need an extra 2-3 minutes in the oven.

Egg-Free Options

Replace the 2 eggs with 2 flax eggs (mix 2 tbsp ground flaxseed with 6 tbsp water, let sit for 5 minutes). For extra moisture, add 1 tbsp applesauce to the batter. The cake will hold together well and maintain its tender crumb, though it may be slightly denser. Bake for the full 35 minutes to ensure even cooking.

Lower-Sugar Version

Reduce the 1.5 cups granulated sugar to 1 cup, and replace ½ cup with ½ cup unsweetened applesauce or mashed banana. The cake will still be sweet but lighter. For extra flavor, add 1 tsp cinnamon or ½ tsp almond extract to the batter. Keep an eye on baking time—sugar-free versions may need 5 minutes less to avoid over-browning.

Nut-Free Considerations

This recipe is naturally nut-free, but if you’re avoiding cross-contamination, use certified nut-free ingredients. Check your vanilla extract and flour labels—some brands process in facilities with nuts. For extra safety, bake in a clean, dedicated oven if nut allergies are severe. The cake’s simplicity makes it a safe bet for nut-free diets.
