I love having easy dessert recipes that I can throw together quickly. Because you never know when an impromptu party opportunity is going to happen. Those impromptu parties are the best! But I hate to show up empty-handed. That’s one reason I usually keep some vegan chocolate chip cookies in the freezer. But there are times that call for something even better than cookies!
That’s where these strawberry chocolate cake bars come in handy!
You can find the full printable recipe, including ingredient quantities, below. But first, here are some explanations of ingredients and steps to help you make this recipe perfect every time.
- Vegan sour cream — You’ll need some plain vegan sour cream for this recipe. I use either Tofutti’s or Forager.
- Vegetable oil — We’ll use a neutral oil, like canola oil or even olive oil.
- Plant-based milk — Use your favorite plant-based milk, whether it be soy milk, oat milk, almond milk, cashew milk, or even pecan milk.
- Chocolate Cake Mix — There are plenty of chocolate cake mixes to choose from these days, including some that I refer to as accidentally vegan. For example, Duncan Hines makes many varieties of chocolate cake mixes without eggs or dairy. You can also choose organic vegan brands, such as Annie’s or Simple Mills.
- Strawberry Cake Mix — The same is true for strawberry cake mixes as well.
- Chocolate chips — Use this dairy-free chocolate chips guide to find the best vegan chocolate chips for you!
How to Make Strawberry Chocolate Bars
- Create the creamy base by stirring together vegan sour cream, vegetable oil, and plant-based milk.
- Make the chocolate layer by combining the cake mix with the creamy base. Press this into the prepared pan.
- Make the strawberry layer by combining the cake mix with the creamy base. Press this into the prepared pan.
- Bake for 45 to 50 minutes until done.
Here are more detailed step-by-step instructions.
Step One: Make the Creamy Base
Stir together vegan sour cream, vegetable oil, and plant-based milk.
Step Two: Prepare the Chocolate Layer
- Pour the chocolate cake mix into a mixing bowl.
- Pour in half the creamy mixture and stir to combine. You will have a thick batter, more similar to cookie dough.
- Press this into the bottom of your prepared 9×13 pan.
- Sprinkle half the chocolate chips over the top of this layer.
Step Three: Prepare the Strawberry Layer
- Rinse out your mixing bowl and dry.
- Pour the strawberry cake mix into the bowl.
- Add the remaining creamy mixture and stir to combine.
- Gently press this layer over the top of the chocolate layer. It helps to get your fingers wet and press the strawberry batter evenly across the top.
- Sprinkle the top with the remaining chocolate chips.
Step Four: Bake
Bake the bars for 45 to 50 minutes. When there done, remove them from the oven and set aside to cool. These bars will thicken as they cool, so allowing them this time will help them cut into better, firmer slices.
Cake Mix Bars Toppings
You can serve these chocolate strawberry bars as-is, or you can add some tasty toppings, like any of the following:
- Vegan Chocolate chips
- Chopped nuts (like walnuts, pecans, or even almonds)
- Colorful sprinkles
- Vanilla drizzle (optional). I like using this vegan royal icing to drizzle over the top.
Can you make cake mix bars without eggs?
It’s easy to make cake mix bars without egg, whether using a mix or making your own homemade brownies. A simple substitute is to use 1/4 cup of vegan sour cream for each egg in your recipe to keep your bars moist and delicious!
What is the difference between cake mix and brownie mix?
Most chocolate cake and brownie mixes will have a lot of the same ingredients, including flour, cocoa powder, sugar, and so on. However, the main difference is that cake mixes will have some kind of chemical leavening, like baking powder and baking soda.
- You can try different cake mix flavors based on your preference, such as cherry, or even a yellow cake mix.
- Be sure to look at the cake mix ingredients to make sure they’re made without eggs or dairy.
- You can substitute gluten-free cake mixes to make gluten-free bars.
- This makes a very thick batter, more like cookie dough, but the results are delicious, fudgy cake mix brownie bars!
To keep theses bars nice and soft, be sure to store them in an airtight container. They will keep at room temperature for up to 3 days, in the fridge for up to 10 days, and they can be frozen for up to 2 months.
