How to Make Raspberry Sheet Cake

Prepare Oven and Pan: Preheat your oven to 350°F (175°C). While it heats, line a 9″x13″ sheet pan with parchment paper and lightly grease it for easy removal.
Mix Dry Ingredients: In a mixing bowl, whisk together the all-purpose flour, baking powder, and salt until well combined. This ensures an even distribution of the leavening agent!
Cream Butter and Sugar: In a separate bowl, beat the softened unsalted butter until light and fluffy. Gradually add in the sugar, continuing to mix until it’s fully incorporated and creamy.
Combine Mixtures: Pour the dry ingredients into the butter and sugar mixture. Add the raspberry puree and whole milk. Stir everything together until just combined, making sure not to overmix.
Incorporate Egg Whites: In a large mixing bowl, beat the egg whites until stiff peaks form. Gently fold these into the batter, making it light and airy while keeping those beautiful bubbles intact.
Bake: Pour the batter into your prepared sheet pan and smooth it out evenly. Bake for 40-45 minutes, or until a toothpick inserted in the center comes out clean. Allow the cake to cool completely in the pan on a wire rack.
Prepare Frosting: In a mixing bowl, beat the softened butter with powdered sugar until combined. Melt the white chocolate and let it cool slightly, then add it to the butter mixture along with heavy cream, vanilla extract, and a pinch of salt. Beat until fluffy and smooth!
Frost the Cake: Once the cake is completely cooled, spread a generous layer of white chocolate frosting across the top. For a decorative touch, sprinkle crushed freeze-dried raspberries on top for a pop of color and flavor.

Optional: Serve slices with a dollop of whipped cream for an extra indulgence.

Thawing: To enjoy a slice, simply remove it from the freezer and let it thaw in the fridge overnight or at room temperature for a couple of hours.

Expert Tips for the Best Raspberry Sheet Cake

Use Fresh Ingredients: Ensure all ingredients, especially baking powder, are fresh. Stale ingredients can lead to a dense cake that doesn’t rise properly.
Room Temperature Egg Whites: Always whip egg whites to stiff peaks at room temperature for a lighter, fluffier texture in your Raspberry Sheet Cake.
Cool Completely: Allow the cake to cool completely before frosting to prevent the frosting from melting. Patience pays off in achieving that perfect look and taste!
High-Quality Chocolate: Choose high-quality white chocolate for your frosting. It makes a significant difference in flavor and overall creaminess.
Don’t Overmix: When combining wet and dry ingredients, mix until just combined. Overmixing can lead to a tough cake instead of a tender, moist one.
Garnish with Style: For an eye-catching presentation, top the frosted cake with crushed freeze-dried raspberries. Not only does it look appealing, but it also enhances the raspberry flavor!

Make Ahead Options

These delicious Raspberry Sheet Cakes are perfect for meal prep enthusiasts! You can prepare the cake base up to 24 hours in advance by baking and cooling it completely, then wrapping it tightly in plastic wrap to maintain its moisture. The white chocolate frosting can be made ahead as well and stored in an airtight container in the refrigerator for up to 3 days. When you’re ready to serve your Raspberry Sheet Cake, simply frost the cake and garnish with crushed freeze-dried raspberries. This not only saves you time but also ensures your cake tastes just as delightful as freshly made when the moment calls for celebration!

Raspberry Sheet Cake Recipe FAQs

What kind of raspberries should I use for this recipe?
Absolutely! Fresh raspberries are best as they provide the brightest flavor. However, if fresh ones aren’t available, you can opt for frozen raspberries. Just remember to thaw and drain them before pureeing to avoid excess moisture in the batter.

How long can I store the Raspberry Sheet Cake?
You can store your delightful Raspberry Sheet Cake in an airtight container in the refrigerator for up to 4 days. This will help maintain its moisture and ensure it stays fresh. For longer storage, follow the freezing instructions below.

Can I freeze the Raspberry Sheet Cake?
Very! To freeze, wrap individual slices in plastic wrap, then place them in a freezer-safe container or freezer bag. This way, it can last up to 3 months in the freezer. When you’re ready to enjoy it, just let the slices thaw in the fridge overnight, or leave them out at room temperature for a couple of hours.

My cake didn’t rise; what could have gone wrong?
It’s disappointing when that happens! Ensure that your baking powder is fresh—stale baking powder can cause flat cakes. Additionally, avoid overmixing the batter; mixing too much can knock out the air needed for proper rising. Lastly, make sure the oven is fully preheated before baking for even cooking and optimal height!

Are there any dietary considerations with this cake?
Of course! This Raspberry Sheet Cake can easily accommodate dietary restrictions. Substitute the all-purpose flour with a gluten-free blend for gluten-sensitive individuals, and use almond milk instead of whole milk for a dairy-free version. You can even swap the butter for margarine or coconut oil for a dairy-free or vegan option. Just check the ingredients of your white chocolate and powdered sugar for any allergens.

Can my pets have any part of this cake?
Not at all! While raspberries are generally safe in small amounts for some pets, this cake contains sugar and white chocolate, which are harmful to dogs (and cats too!). It’s best to keep this delicious treat all for the humans!
