Ingredients for Milk Bar White Sheet Cake
Gathering your ingredients for this Milk Bar White Sheet Cake is half the fun! Each component plays a vital role in creating that perfect combination of moisture and sweetness. Here’s what you’ll need:
- Butter: Room-temperature butter is key for a fluffy texture in your batter.
- Granulated Sugar: This sweetener adds essential sweetness and helps in achieving the right consistency.
- Oil: A neutral oil, like canola, keeps the cake moist.
- Egg Whites: Using just the whites helps create a light cake; they aid in structure without the richness of yolks.
- All-purpose Flour: The base of our cake, providing structure and body.
- Baking Powder: This leavening agent ensures the cake rises beautifully.
- Baking Soda: Works in tandem with the baking powder for a fluffy crumb.
- Salt: Just a pinch enhances the cake’s sweetness and overall flavor.
- Buttermilk: Adds moisture and a delightful tang. If you don’t have any, regular milk with a splash of vinegar can work as a substitute.
- Vanilla Extract: Opt for pure vanilla for the best flavor; it makes a world of difference!
- Milk: Used for the milk soak to keep the cake moist and delicious.
- Cream Cheese: Room temperature for the frosting; it adds creaminess and balance.
- Powdered Sugar: This is essential for a smooth, sweet frosting; adjust the quantity based on your sweetness preference.
- Clear Vanilla Extract: Ideal for frosting; it keeps the frosting a pure white, perfect for presentation.

How to Make Milk Bar White Sheet Cake
Step 1: Preheat and Prepare
Start by preheating your oven to 350℉. This step is crucial because it ensures an even bake. While the oven warms up, take a 9×13 inch baking pan and grease it with butter or oil. To make it even easier to remove the cake later, line the bottom with parchment paper. Getting this right means your cake will come out perfectly without sticking, ready to be adorned with frosting!
Step 2: Make the Batter
Next, let’s whip up that luscious batter! In a large mixing bowl, beat the room-temperature butter and granulated sugar together until light and fluffy. This might take about 3 minutes, so don’t rush it! Then, add the oil, egg whites, and vanilla extract. Mix everything together until well combined. The goal is to create a smooth and creamy texture that feels velvety. Your batter will be the foundation for the fantastic flavor of this Milk Bar White Sheet Cake.
Step 3: Combine Dry Ingredients
Now it’s time to bring in the dry ingredients! Gradually add in the all-purpose flour, baking powder, baking soda, and salt. This might look like a lot, but trust me, it’s worth it! As you mix, alternate adding the buttermilk to keep things smooth. You don’t want to overmix here; just stir until the flour is incorporated. This helps keep your cake light and airy, which is exactly what you want!
Step 4: Bake the Cake
Spread the batter evenly into your prepared pan. Bake in your preheated oven for 25 to 30 minutes. I always set a timer and check a few minutes early! Your cake is done when a toothpick inserted in the center comes out clean. Once baked, let it cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely. Cooling is essential because it helps the cake set perfectly!
Step 5: Prepare the Milk Soak
While your cake cools, let’s make the milk soak! In a small bowl, combine the 1/3 cup of milk with the teaspoon of vanilla extract. This simple mixture enhances the cake’s moisture and flavor. Set it aside until you’re ready to soak your layers. You’ll be amazed at how this step transforms your cake!
Step 6: Make the Frosting
Time to make that dreamy frosting! In another mixing bowl, beat the room-temperature butter until it’s fluffy and light. If you’re feeling adventurous, you can add a pinch of salt for extra flavor! Then, incorporate the cream cheese and continue mixing until smooth. Gradually add powdered sugar, mixing well after each addition to avoid clouds of sugar. Finally, stir in the clear vanilla extract, ensuring your frosting is velvety and sweet. This frosting is what dreams (and cakes) are made of!
Step 7: Create the Crumb Topping
Let’s add some delicious texture with a crumb topping! In a bowl, mix the crumb ingredients: flour, sugars, baking powder, salt, oil, and clear vanilla. Use a fork to blend everything together until small clusters form. Spread the mixture on a lined baking sheet and bake at 350℉ for about 20 minutes. Allow the crumbs to cool, and you’ll add the perfect crunch to your cake!
Step 8: Assemble the Cake
Now, it’s time to bring all the elements together! Cut the cake into two layers. Brush the top of the bottom layer generously with your milk soak. Spread a thick layer of frosting over it, then place the second layer on top and repeat with the milk soak. Finally, frost the entire cake and generously sprinkle the delicious crumbs on top. Allow it to sit for an hour before slicing, helping all those wonderful flavors meld together!

Tips for Success
- Always use room-temperature ingredients for better mixing and texture.
- Don’t overmix the batter; a few lumps are okay for a fluffy cake!
- Keep an eye on the baking time, as ovens can vary. Check the cake early!
- Let the cake cool completely before frosting to ensure the layers stay intact.
- Feel free to adjust the sweetness of the frosting by adding more or less powdered sugar.
Equipment Needed
- Baking Pan: A 9×13 inch pan is ideal; a 10×15 inch will work, too.
- Mixing Bowls: Use medium and large-sized bowls for ease.
- Electric Mixer: A hand mixer is perfect; a whisk can work, but it takes more effort!
- Spatula: A silicone spatula is great for folding and scraping.
- Wire Rack: Essential for cooling your cake properly; an upside-down plate can substitute.
Variations
- Citrus Twist: Add zest from a lemon or orange for a bright citrus flavor and a refreshing twist.
- Chocolate Lovers: Swirl in some cocoa powder for a chocolate sheet cake version or drizzle melted chocolate over the frosting.
- Nutty Delight: Stir in some finely chopped nuts like walnuts or pecans into the batter for added texture and flavor.
- Gluten-Free: Substitute all-purpose flour with a gluten-free baking blend to make this cake suitable for gluten sensitivities.
- Vegan Option: Replace butter with vegan margarine, use aquafaba or flax eggs instead of egg whites, and choose dairy-free milk and cream cheese for the frosting.
Serving Suggestions
- Pair with Ice Cream: A scoop of vanilla or chocolate ice cream complements the cake perfectly.
- Fresh Fruit: Serve with fresh berries or sliced strawberries for a refreshing contrast.
- Presentation: Garnish with extra sprinkles or edible flowers for a festive touch.
- Coffee or Tea: Enjoy a slice with freshly brewed coffee or herbal tea for a delightful afternoon pick-me-up.
