Ingredients
Main Ingredients for Boston Cream Bars
– 1 cup all-purpose flour
– 1/2 cup granulated sugar
– 1/2 cup unsweetened cocoa powder
– 1 teaspoon baking powder
– 1/2 teaspoon baking soda
– 1/4 teaspoon salt
– 1/2 cup buttermilk
– 1/4 cup vegetable oil
– 1 large egg
– 1 teaspoon vanilla extract
The base of your Boston Cream Bars starts with all-purpose flour. This gives the bars structure. Granulated sugar adds sweetness, while unsweetened cocoa powder gives that rich chocolate taste. Baking powder and baking soda help the bars rise. Salt balances the flavors. Buttermilk adds moisture and a nice tang. Vegetable oil keeps the bars soft. The egg binds everything together, and vanilla extract gives a warm flavor.
Ingredients for Chocolate Ganache
– 8 ounces semi-sweet chocolate, chopped
– 1 cup heavy cream
For the chocolate ganache, semi-sweet chocolate is key. It adds a rich chocolate layer. Heavy cream makes it smooth and creamy. Heat the cream and pour it over the chocolate to melt it, creating a glossy finish.
Ingredients for Vanilla Pastry Cream
– 2 cups whole milk
– 2/3 cup granulated sugar
– 1/4 cup cornstarch
– 1/4 teaspoon salt
– 4 large egg yolks
– 2 tablespoons unsalted butter
– 1 teaspoon vanilla extract
Vanilla pastry cream is the heart of this dessert. Whole milk makes it rich and creamy. Granulated sugar adds sweetness, and cornstarch thickens it up. Salt enhances the flavors. Egg yolks give it a rich color and taste. Unsalted butter adds a silky texture, and vanilla extract gives it that classic flavor.

Step-by-Step Instructions
Preparing the Cake Base
1. Preheat your oven to 350°F (175°C). Grease and flour an 8×8 inch baking pan. This keeps the cake from sticking.
2. In a large bowl, mix the dry ingredients. Combine 1 cup of all-purpose flour, 1/2 cup of granulated sugar, 1/2 cup of unsweetened cocoa powder, 1 teaspoon of baking powder, 1/2 teaspoon of baking soda, and 1/4 teaspoon of salt.
3. In another bowl, mix the wet ingredients. Whisk together 1/2 cup of buttermilk, 1/4 cup of vegetable oil, 1 large egg, and 1 teaspoon of vanilla extract.
4. Pour the wet mix into the dry mix. Stir until just combined. Don’t overmix; lumps are fine.
Baking and Cooling
1. Pour the batter into your prepared baking pan. Smooth the top with a spatula.
2. Bake for 25-30 minutes. To check for doneness, insert a toothpick into the center. If it comes out clean, it’s done.
3. Cool the cake in the pan for 10 minutes. Then, transfer it to a wire rack to cool completely.
Preparing Creams and Ganache
1. To make the vanilla pastry cream, heat 2 cups of whole milk in a saucepan until steaming.
2. In a separate bowl, whisk 2/3 cup of granulated sugar, 1/4 cup of cornstarch, and 1/4 teaspoon of salt.
3. Whisk 4 large egg yolks in another bowl. Slowly add half of the hot milk to the yolks while whisking.
4. Return this mix to the saucepan and cook over medium heat. Whisk constantly until thick. Remove it from heat, stir in 2 tablespoons of butter and 1 teaspoon of vanilla extract. Cover with plastic wrap and chill until cool.
5. For the chocolate ganache, heat 1 cup of heavy cream in a small saucepan until it simmers. Pour it over 8 ounces of chopped semi-sweet chocolate and let it sit for 5 minutes. Stir until smooth.
Assembling the Bars
1. Once the cake has cooled, cut it in half horizontally. You now have two layers.
2. Spread the vanilla pastry cream on the bottom layer. Carefully place the top layer back on.
3. Pour the chocolate ganache over the top layer. Spread it evenly with a spatula.
4. Refrigerate the assembled bars for at least 1 hour. This helps the ganache set before you slice them into squares.

Tips & Tricks
Baking Tips for Perfect Bars
To make sure your Boston Cream Bars bake evenly, it’s key to preheat your oven to 350°F (175°C). This helps the cake rise just right. Greasing and flouring your pan is also important. It helps the cake slide out easily.
To check if your cake is done, use a toothpick. Insert it into the center of the cake. If it comes out clean, your cake is ready. If it has some batter on it, bake for a few more minutes.
Creams and Ganache Tips
When making vanilla pastry cream, avoid lumps by whisking well. Always mix the sugar, cornstarch, and salt before adding to the hot milk. This helps it blend smoothly. If your cream does get lumpy, you can strain it through a fine sieve.
For a glossy ganache, let the chopped chocolate sit in the warm cream for five minutes. Stir gently until smooth. If you want it thicker, let it cool slightly before pouring it over your bars.
Presentation Tips
For a lovely display, serve your Boston Cream Bars on a nice platter. You can dust them with powdered sugar for a sweet touch. Adding chocolate curls or fresh berries makes the dessert look even nicer. These simple details impress your guests and make the dessert feel special.

Variations
Flavored Creams
You can change the taste of your Boston Cream Bars by adding flavors. Try adding a bit of espresso to the pastry cream for a coffee kick. Just mix one tablespoon of espresso powder in with the sugar and cornstarch when you prepare the cream. For chocolate lovers, mix in some cocoa powder to make a rich chocolate pastry cream.
You can also infuse your ganache with liqueurs. A splash of orange liqueur or rum can add a fun twist. Just add about one to two tablespoons of liqueur to the chocolate ganache mixture. This will give your bars a unique flavor that surprises everyone.
Gluten-Free Option
If you need a gluten-free treat, you can still enjoy these bars. Simply swap out the all-purpose flour with a good gluten-free flour blend. Many brands work well for baked goods, so choose one that you like.
Make sure to check the other ingredients too. Some baking powders and other mixes may contain gluten. Always read labels closely to ensure everything is safe. This way, everyone can enjoy your delicious Boston Cream Bars.
Mini Boston Cream Bars
Mini Boston Cream Bars are perfect for parties or as a small treat. To make these bite-sized versions, simply cut the cake into smaller squares or use a mini muffin pan to bake.
Adjust the baking time if you use a mini pan. Smaller sizes will bake faster, so check them after about 15 to 20 minutes. This way, you’ll have cute, little desserts that are easy to grab and enjoy.
For the filling, you can still use the same pastry cream and ganache. They will taste just as great in mini form!
Storage Info
Refrigeration Guidelines
To keep your Boston Cream Bars fresh, store them in the fridge. Wrap the assembled bars tightly in plastic wrap. This helps prevent them from drying out. If you use an airtight container, that works too! In the fridge, the bars last about 3 to 4 days. After this, they may lose some texture and taste.
Freezing Instructions
For long-term storage, freezing is a great option. Cut the bars into squares before freezing. Wrap each piece in plastic wrap, then place them in a freezer bag. This way, they stay fresh for up to 3 months. When you want to enjoy them again, take out the bars and let them thaw in the fridge. This keeps the texture nice.
Serving after Storage
When serving the bars after storage, you can enjoy them cold straight from the fridge. If you like them a bit warmer, heat them in the microwave for about 10 to 15 seconds. Just be careful not to overheat! This can make the chocolate ganache too soft. The bars will still taste delicious, but keeping an eye on the texture is key. Enjoy those sweet bites!
