Gluten-Free Vegan Boston Cream Pie - Rhian's Recipes (1)

Contrary to what the title may suggest, Boston Cream Pie is actually a sponge cake, and I was inspired to make this gluten-free and vegan version because I used to really love Boston cream pie donuts.

The combination of the creamy custard with velvety chocolate ganache is absolutely heavenly, and I was keen to recreate this in a dietary requirement-friendly sweet treat.

For the cake, I used my go-to sponge recipe: it comes together in one bowl, uses familiar ingredients and is vegan, gluten-free and refined sugar free. It's moist and fluffy, and makes the perfect base for a layer cake like this Boston Cream Pie.

For the custard filling, I used unsweetened cashew milk, which I love because it's so naturally sweet and creamy, and a shop-bought custard powder.

You'll be surprised that a lot of custard powders are actually naturally vegan and gluten-free, so be sure to look out for that if you have any dietary requirements. If you can't get hold of cashew milk, unsweetened almond milk would also work.

And now for my favourite part of this Gluten-Free Vegan Boston Cream Pie - the chocolate ganache topping! My version here is so easy to make as all you need to do is melt some dark chocolate and mix in any type of milk.

This creates a seriously indulgent, melt-in-your-mouth silky ganache that stays pleasantly soft even after having been refrigerated, as opposed to just using melted chocolate, which will harden completely when refrigerated, making the cake impossible to cut.

If you'd like to keep the cake completely refined sugar free, you could buy a refined sugar free dark chocolate, or use my coconut oil-based chocolate sauce recipe here.

Ingredients

For the cake:

For the custard:

  • 300 ml (1 ¼ cup) unsweetened cashew milk (or sub any other milk)
  • 2 tablespoons maple syrup to taste (or sub any other sweetener)
  • 1 teaspoon vanilla extract
  • 3 tablespoons custard powder (ensure vegan/gluten-free if necessary - the amount you need may vary depending on the brand)

For the chocolate ganache*:

  • 40 g (1.5oz) dark chocolate* (ensure vegan if necessary)
  • 6 tablespoons unsweetened almond milk (or any other plant-based milk)

Instructions

For the cake:

  • Preheat oven to 180 degrees Celsius (350 degrees Fahrenheit)

  • Place the coconut oil in a large bowl and melt over a saucepan of boiling water or in the microwave (skip this step if using any other oil)

  • Once melted, add the milk to the same bowl along with the vinegar, maple syrup, vanilla, salt and ground almonds

  • Sift in the flour, baking powder and bicarbonate of soda

  • Mix well, adding a tiny splash more milk if it’s looking too dry

  • Transfer mixture between two greased baking tins lined with baking paper (I used two 7inch/18cm springform baking tins)

  • Bake in oven for around 15 minutes until risen and an inserted skewer comes out clean

  • Once done, turn the cakes out onto wire racks and leave to cool completely before applying the custard

For the custard:

  • Heat up the milk in a saucepan with the maple syrup and vanilla

  • Dissolve the custard powder in a separate bowl in a little extra milk

  • Once the milk in the saucepan is steaming, add a little of the hot milk to the bowl with the dissolved custard powder, mix well and transfer the custard powder mixture to the saucepan

  • Mix well and keep stirring on a low heat for a few minutes until thickened. If it's looking too thick, add a little extra milk, and if it's looking too thin then add some more custard powder as required - in general, it's better for the custard to be too thick than too thin

  • Leave the custard to cool for around 30 minutes before applying to the cake - it doesn’t have to be completely cooled but it should have firmed up a little

For the chocolate ganache:

  • Melt the chocolate either over a bain-marie or in the microwave, add the milk and mix well

To assemble:

  • Place one half of the sponge on a cake stand or plate, and spread the custard evenly on top of it

  • Place the other half of the sponge on top of the custard

  • Pour the chocolate ganache over the top of the cake and spread evenly

  • I’d recommend keeping the cake in the fridge for a few hours until the chocolate ganache has set before cutting to avoid making too much of a mess

  • Tastes best when fresh, but keeps covered in the fridge for up to a few days

Notes

*You can alternatively usealmond flour

**If you'd like to keep the cake completely refined sugar free, you could buy a refined sugar free dark chocolate, or use my coconut oil-based chocolate sauce recipe here.

    Have you tried making any other sizes of cake? Thinking about using 9 inch pans but not sure the cake is substantial enough and doubling might be too much. Figured it’s worth seeing if you ever did it another way. Looking forward to making this for my 40th birthday next week!!

      I think for 9 inch pans you could use 1.5 times the recipe, so half the recipe extra added onto this recipe! You can easily get calculations for this by moving the sliding scale on the recipe next to the number of servings to '12 slices' instead of '8'. Hope that helps!

    Do you think it’d be fine to put the batter into cupcake tins?!

Bavarian cream involves milk, eggs, sugar, and often vanilla extract, the same as Boston cream. But then the two ingredient lists diverge: Bavarian cream includes heavy cream and gelatin, while Boston cream involves cornstarch.

What is the difference between Bavarian cream and Boston cream filling? ›

The use of heavy cream and gelatin means Bavarian cream sets more thoroughly, creating a thicker, richer consistency.

Additionally, they're not even eaten the same way.
