What Goes Into This Recipe:
Boxed Cake Mix: I like to use a storebought mix to make this recipe. It tastes great and comes together fast!

How to Make This Chocolate Strawberry Cake?
- Step 1: Mix up the cake batter and pour into two 8-inch round cake pans.
- Step 2: Bake cakes and allow them to cool completely before frosting.
How to Make Strawberry Buttercream?
- Step 3: Heat water, strawberries, and salt in a medium saucepan.
- Step 4: Mash strawberries as the mixture boils. Reduce mixture to ~½ cup then set aside to cool. If you want a super smooth mixture, you can use an emulsion blender.
- Step 5: Using a stand mixer, beat butter until fluffy then mix in the vanilla, powdered sugar, and heavy cream
- Step 6: Add in the cooked strawberries, a few drops of the strawberry oil, and a few drops of the gel food coloring. Mix until fluffy.
How to Decorate Valentine’s Day Cake?
- Step 7: Place the first cake layer on a cake board with a bit of buttercream underneath. Add an even layer of strawberry frosting, then top with the second layer. Fill any gaps with more buttercream and refrigerate for a few minutes to set.
- Step 8: Frost the cake with the remaining buttercream. For a smooth finish, use a cake scraper or apply a crumb coat followed by a final layer of frosting (requires a second batch of frosting). Refrigerate until set.
- Step 9: Combine chocolate chips and heavy cream in a microwave-safe bowl and heat until smooth. Then pour over the top of the cake allowing it to drip down the sides.
- Step 10: Decorate the top with strawberries, candy, and chocolate pieces.

Expert Tips
Cake- If the tops of the cake bake into a dome simply use a serrated knife to slice off the dome to create a flat top.
Frosting- If you want to make a super smooth cake like this German Chocolate Cake, double the frosting recipe and do a crumb coat, refrigerate, then do a final smooth coat. Pictures in this post show only one batch of frosting used and I find I love how it looks.
Frosting Flavor- Adding 2-4 drops of LorAnn Strawberry Oil makes the strawberry flavor stand out. Start with only two drops, taste, and then add more. A little oil goes a long way.
Filling- Add a layer of strawberry jam or thinly sliced strawberries between the cake layers for an extra burst of flavor!
Frequently Asked Questions
Store the cake and any cake slices in an airtight container in the refrigerator for up to 5 days. Keeping the air away will keep the cake tender and won’t dry out.
I like to add sour cream, heavy cream, vanilla, an extra egg, cocoa powder, and espresso powder. This create a tender crumb and deep chocolate flavor.
Yes! Use frozen strawberries for the frosting the same as you would fresh. I don't recommend using them to decorate though.

Notes
- *If you prefer a homemade chocolate cake, use this recipe but cut it in half, it’s my favorite!
- *If you don’t have the extra ingredients to doctor the box mix just follow the directions on the back of the box and bake accordingly.
- *If you have a thermometer, the cakes will be done at an internal temperature of 205-210°F
- *Strawberry Oil can be found in the baking/decorating aisle of most grocery stores. It comes in a tiny bottle but you only need a few drops. You can also buy it online here.
- *You can use fresh or frozen strawberries, just make sure they are thawed if using frozen.
- *If your strawberry mixture is too chunky you can smooth it out by using an immersion blender on it.
- *The strawberry buttercream makes enough for a single coat without a crumb coat. If you want a super smooth finish with a sharp edge (like seen here on my pink and gold cake), I recommend doubling the frosting, doing a crumb coat then a final coat.
- *Refrigerate cake and any leftovers for up to 5 days. It’s best to keep sliced cake in an airtight container to prevent it from drying out.
