This cherry sheet cake has been a celebration staple in my kitchen ever since I first made it for a summer cookout. I discovered this version while experimenting with a white cake mix and a jar of maraschino cherries I hadn’t gotten around to using. The idea of pureeing the cherries and folding them into a boxed mix sounded odd at first, but the result was a tender, evenly flavored cake with pockets of cherry brightness and a gentle rosy color from the Jell-O. It’s one of those desserts that everyone asks about — from picky teenagers to dessert-first adults — because it’s reliably moist, pleasantly sweet, and topped with a frosting that adds a delicate almond note instead of overwhelming sugar.

I often make this for potlucks because it scales easily and slices beautifully straight from a 9x13 pan. The texture is soft but substantial enough to serve at picnics, birthdays, or a quiet weekend treat. What makes this recipe special is its simplicity: a few pantry staples combine with the charm of real maraschino cherries and a splash of almond extract to create a dessert that tastes homemade without hours of work. I’ll share exact measurements, troubleshooting tips, and variations so you can customize it to your taste or dietary needs.

Ingredients

• White cake mix (1 package): A dependable base that gives consistent rise and crumb. I use a standard American brand; opt for a high-quality mix for better flavor. Avoid mixes labeled "pound cake" style — choose a classic white or vanilla cake mix.
• Eggs (3): Room temperature eggs incorporate more easily and help the cake rise evenly. Let them sit out 20–30 minutes before mixing for best results.
• Vegetable oil (3/4 cup): Keeps the crumb moist and tender. You can substitute light olive oil or canola oil if preferred, but avoid strongly flavored oils.
• Water (1/2 cup): Measured at room temperature to keep batter consistency correct; you can use milk for slightly richer flavor.
• Cherry Jell-O (3 oz packet): Adds concentrated cherry flavor and a hint of rosy color. Use a standard 3-ounce gelatin dessert packet (Jell-O brand or store equivalent).
• Maraschino cherries (10–12 oz jar), drained: Puree these for the batter and reserve a few whole cherries for garnish. Drain well to avoid excess syrup diluting the batter.
• Frosting - Butter (1/4 cup) softened: Use unsalted butter and taste as you go; salted butter can push the frosting toward salty.
• Frosting - Cream cheese (4 oz) softened: Adds tang and keeps the icing creamy; room temperature makes for a smooth emulsion.
• Almond extract (2 tsp): Powerful concentrated flavor — use sparingly and taste the frosting before adding more.
• Powdered sugar (3 cups): Sift if lumpy for a silky frosting; adjust quantity slightly for desired thickness.
• Milk (2–3 tbsp): Use to reach the right frosting consistency — start with less and add more if needed.

Instructions

Preheat and prepare pan: Set the oven to 350°F (177°C). Grease a 9x13-inch pan thoroughly with butter or nonstick spray and line with parchment if you prefer easier removal. Proper pan preparation prevents sticking and ensures clean slices. Puree the cherries: Drain the maraschino cherries well, discarding excess syrup. Place them in a blender or food processor and pulse until smooth — about 15–30 seconds. The puree should be lump-free so it blends evenly into the batter without creating pockets of moisture. Combine wet and dry ingredients: In a large mixing bowl, add the cake mix, eggs, 3/4 cup vegetable oil, and 1/2 cup water. Beat on medium speed until smooth, about 1–2 minutes. Add the 3-ounce cherry Jell-O packet and the cherry puree, then mix until fully incorporated. The batter will be slightly thinner and tinted pink; this is normal. Bake: Pour the batter evenly into the prepared 9x13 pan and smooth the top with a spatula. Bake at 350°F for about 28–32 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Avoid overbaking — the cake continues to set as it cools. Cool completely: Let the cake cool in the pan on a wire rack for at least 30–40 minutes so the crumb firms up. Cooling fully before frosting prevents the icing from melting and becoming runny. Make the almond buttercream: In a mixing bowl, cream together 1/4 cup softened butter and 4 oz softened cream cheese until smooth and fluffy. Add 3 cups powdered sugar gradually, then beat in 2 teaspoons almond extract. Add 2–3 tablespoons milk one tablespoon at a time until the frosting spreads easily but remains thick. Frost and serve: Once the cake is completely cool, spread the almond buttercream evenly over the top using an offset spatula. Garnish with a few whole drained maraschino cherries and, if desired, a sprinkle of slivered almonds. Slice into 16 squares and enjoy.

Storage Tips

To keep the cake moist, store it covered in the refrigerator because the frosting contains cream cheese and butter. Place plastic wrap directly on the frosting surface or use an airtight container to prevent the cake from absorbing other fridge smells. Leftovers maintain quality for 3–4 days refrigerated. For longer storage, freeze unfrosted slices individually wrapped in plastic and placed in a freezer-safe bag for up to 3 months; thaw in the fridge and make the frosting fresh or freeze the frosted cake whole and allow to thaw slowly in the fridge to preserve texture.

Ingredient Substitutions

If you prefer a dairy-free option, replace the butter and cream cheese in the frosting with dairy-free alternatives and use a nondairy milk like almond or oat milk; note the flavor will shift. For a gluten-free adaptation, use a gluten-free white cake mix and confirm other ingredients like Jell-O are gluten-free. If you want a less sugary frosting, reduce powdered sugar to 2 1/2 cups and add a touch more almond extract or a teaspoon of vanilla for balance. For a boozy twist, a tablespoon of kirsch or cherry liqueur in the frosting complements the cherries nicely.

Serving Suggestions

Serve this cake slightly chilled or at room temperature. Pair slices with a scoop of vanilla ice cream, a drizzle of warm chocolate sauce, or a dollop of lightly whipped cream. Garnish with toasted sliced almonds and a few reserved maraschino cherries for a festive presentation. It’s great at picnics, afternoon tea, or as a casual dessert after a family meal. For a special occasion, top each slice with a fresh mint leaf and a few microscopic grinds of lemon zest to brighten the flavors.

Cultural Background

Sheet cakes are a long-standing American tradition for community gatherings because they’re simple to bake in large quantities and share easily. This cherry adaptation draws on mid-20th-century convenience baking — boxed cake mixes and flavored gelatin were staples in many households for quick desserts. The combination of cherries and almond offers a nod to classic European flavor pairings, while the modern buttercream keeps the cake rooted in contemporary American comfort food.

Seasonal Adaptations

In summer, swap maraschino cherries for a mixture of fresh cherries and a few tablespoons of cherry jam to intensify flavor; reduce the Jell-O to 1 1/2 ounces if using hefty fresh fruit to avoid excess moisture. For winter celebrations, add a pinch of cinnamon and nutmeg to the batter and finish the frosting with orange zest for a holiday twist. You can also fold chopped roasted almonds into the batter for a nutty texture variation that works particularly well in autumn.

Meal Prep Tips

Make the cake the day before and chill overnight for easier slicing and cleaner presentation. Keep the frosting in an airtight container at room temperature for a few hours while decorating, but return leftovers to the refrigerator. When transporting to an event, place the pan in a shallow box with a non-slip mat to avoid sliding. If you must stack slices, place wax paper between layers to prevent sticking.

Bringing this cherry sheet cake to a gathering always feels like offering a warm, familiar hug: simple, satisfying, and made with a few heartfelt shortcuts. I hope you enjoy making it as much as my family has — and that it becomes one of your quick-go-to desserts for celebrations and casual evenings alike.
