For the Strawberry Cake
- 1 box white cake mix (standard 15.25 oz box)
- 1 small box strawberry gelatin (like Jell-O)
- 1 cup vegetable oil
- ½ cup milk
- 4 large eggs
- 1 cup mashed sweetened strawberries (Keep the juice! Do not drain)

How to Make Mama Seward’s Strawberry Cake
Step 1: Prep the Oven and Pans
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or line the bottoms with parchment paper to ensure the cakes release cleanly.
Step 2: Mix the Cake Batter
In a large mixing bowl, combine the dry white cake mix and the strawberry gelatin powder. Add the vegetable oil, milk, eggs, and the mashed sweetened strawberries (including all their natural juices). Beat on medium speed with an electric mixer for about 2 minutes, or until the batter is completely smooth and well combined.
Step 3: Bake
Pour the bright pink batter evenly into your two prepared cake pans. Bake in the preheated oven for 25 to 30 minutes. The cakes are done when a wooden toothpick inserted into the center comes out clean.
Step 4: Cool
Remove the cakes from the oven and let them cool directly in their pans for about 10 minutes. Carefully turn them out onto wire cooling racks to cool completely before you attempt to frost them.
Step 5: Whip the Frosting
In a medium mixing bowl, beat the softened butter until it is perfectly smooth and creamy. Gradually add the powdered sugar, mixing well after each addition. Gently fold in the drained mashed strawberries and continue to beat until the frosting is incredibly light and fluffy. (Pro Tip: Make sure your berries are well-drained so the extra liquid doesn’t break your frosting!)
Step 6: Assemble and Chill
Place your first cake layer on a serving plate or cake stand. Spread a generous, even layer of frosting over the top. Place the second cake layer directly over the first, and use the remaining frosting to smoothly cover the top and sides of the entire cake.
Transfer the assembled cake to the refrigerator to chill for about 30 minutes to let the frosting set before slicing and serving.
Serving Suggestions & Delicious Variations

- Serving Pairings: This cake shines when served chilled or at room temperature. Pair it with a scoop of vanilla bean ice cream or a dollop of fresh whipped cream for an extra indulgent treat. It is perfect alongside a hot cup of tea or coffee!
- Cream Cheese Twist: Swap the stick of butter in the frosting for 8 oz of softened cream cheese to create a tangy, rich strawberry cream cheese frosting.
- Add Extra Texture: For a fun variation, fold ½ cup of white chocolate chips or lightly toasted almonds into the cake batter before baking to add richness and a slight crunch.
- Double the Berries: Layer fresh, thinly sliced strawberries between the cake layers along with the frosting for a beautiful presentation and a burst of fresh acidity.
Storage & Freezing Instructions
- Refrigerator Storage: Store the frosted cake in an airtight cake keeper in the refrigerator for up to 3 days to keep it beautifully fresh and moist.
- Freezing Instructions: If you want to freeze the cake, wrap the entirely cooled (but unfrosted) cake layers tightly in plastic wrap, followed by a layer of aluminum foil. They will keep well in the freezer for up to 2 months. Thaw overnight in the refrigerator, bring to room temperature, and frost fresh before enjoying!
