Allergy Free Boston Cream Pie

35


I’m baking up a special dessert that one would never imagine could be made Allergy-Free. Boston Cream Pie! That’s right, allergy free, gluten free, vegan Boston Cream Pie!

I’m from Boston, where this dreamy creation is our favorite traditional dessert. Boston Cream Pie is actually a cake; two layers of tasty yellow cake, filled with a fluffy pastry cream, and topped with a luscious chocolate glaze. But it’s usually heavily dependant on such top allergens as wheat, dairy, eggs, and sometimes soy. So as a tribute to all of us out there living with food allergies, I’ve come up with a version of this special treat that is free of all top allergens. Bake it and celebrate how delicious allergen-free can be!

Allergy-Free Boston Cream Pie

Makes 1 9-inch Cake

  • 2 cups Authentic Foods GF Classical Blend or my Basic Gluten-Free Flour Mix
  • 1/2 teaspoon xanthan gum
  • 1 teaspoon double-acting baking powder
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 1 cup rice milk
  • 1 teaspoon cider vinegar
  • 1/2 cup dairy-free, soy-free vegetable shortening
  • 1 cup granulated sugar
  • 1 Tablespoon Ener-G egg replacer mixed with 1/4 cup rice milk
  • 1 1/2 teaspoons pure vanilla extract
  • 1 recipe Allergy-Free Pastry Cream (recipe follows)
  • 1 recipe Rice Milk Chocolate Glaze (recipe follows)

1  Preheat oven to 325°F. Grease two 9-inch round cake pans, line with cutout parchment paper, grease again, and dust with a little flour mix.

2. Whisk together the flour mix, xanthan gum, baking powder, baking soda, and salt. Set aside.

3. Combine the rice milk and cider vinegar. Set aside.

4. In the bowl of a stand mixer fitted with the paddle attachment, combine the shortening, sugar, egg replacer, and vanilla. Beat on medium speed until light and fluffy, about 2 minutes. Sift in the flour mixture in three batches, alternating with the rice milk, and beginning and ending with the flour mixture. Beat until smooth, scraping down the sides of the bowl as necessary, about 30 seconds.

5.  Divide the batter evenly between the two pans, using an offset spatula to smooth the batter, filling the pan to the edges. Ple

ase note that we are intentionally making thin layers of cake, so don’t worry that it seems short on batter! Smooth the surface.

6. Bake in the center of the oven, 20 minutes until cake is just starting to pull away from the edges of pan, and a skewer inserted into the center of the cake comes out clean.

7.Let cool in the pans on a cooling rack. Once cool, cover the cake pan with a large plate, flip, peel off the parchment paper, and flip the cake back onto your serving platter or cake stand, right side up. Use a frosting spatula to cover top of first layer with Allergy-Free Pastry Cream.

 

8. Repeat process of flipping other layer of cake out of pan, peeling parchment, and onto top of pastry cream layer. Make sure both layers are lined up.

9. Spoon half the Rice Milk Chocolate Glaze over the cake. Let set about 5 minutes, then spoon rest of glaze over top of cake, for a lovely glossy, even layer. Let set several hours at room temperature. Best served room temp. Store covered.

 

Allergy-Free Pastry Cream

Makes about 2 1/4 cups

  • 3 Tablespoons cornstarch
  • 3/4 cup rice milk
  • 3/4 cup dairy-free, soy-free vegetable shortening
  • 3/4 cup caster sugar (very fine)
  • 3/4 teaspoon pure vanilla extract

1.Whisk together cornstarch and rice milk in a small heavy saucepan, until smooth, being sure to whisk out any lumps.

2.Bring to just below a simmer (a scald) over medium-low heat, stirring continuously with a wooden spoon, until it thickens (this happens very quickly once it starts, in about 1 minute or less). Once it’s the consistency of a thick pudding, remove from the heat and stir vigorously until smooth. Set aside to cool.

3. In the bowl of a stand mixer fitted with the paddle attachment, cream the shortening and caster sugar on medium speed for 3 minutes, then add the vanilla. Continue to beat while adding the cooled rice milk mixture, until fully incorporated, about one minute, stopping to scrape down sides as necessary. Beat for 2-3 minutes, or until light and fluffy, making sure you’ve whipped out any lumps. Use at room temperature (it solidifies when chilled).

 

Rice Milk Chocolate Glaze

Makes enough to Glaze One 9-inch cake

  • 3 Enjoy Life Rice Milk Boom Choco Boom bars, or 3/4 cup diary-free, soy-free chocolate chips
  • 3 Tablespoons rice milk
  • 1 Tablespoon plus 1 1/2 teaspoons maple syrup
  • Pinch of salt

1. Chop the chocolate bars into small pieces using a serrated knife.

2. Bring the rice milk to a simmer in a small saucepan over medium-high heat. Remove from heat and stir in the chocolate, stirring till melted. Add maple syrup and salt, and whisk until smooth, about 1 minute. Let cool to room temperature before pouring onto cake.

    Can you replace corn starch with potato starch? My daughter is allergic to corn.

  11. Cybele says:

    Hi Martha:

    I’d probably try tapioca starch first… But yes, you can replace the cornstarch with either tapioca starch, or potato starch, or arrowroot starch.

    Enjoy!

  14. Ashley says:

    This looks amazing! I can’t wait to make this :)

    Did you ever try replacing almond or cococut milk for the rice milk or do you think that can be done?

    Thanks,
    Ashley :)

  15. kankana says:

    This looks lovely and so creamy. Glad to find your gorgeous space from FB and congrats on Top 9

  16. Cybele says:

    Hi Ashley:

    I think either would work fine in place of rice milk, but I would use the coconut milk in the carton, not the kind from a can.

    all best,
    Cybele

  17. Cybele says:

    Kankana:

    So happy you stopped by! Thanks on the congrats.

    all best,

  18. I am so happy to have found your blog! After years of suffering, I just discovered that I have a severe soy allergy. I’m a mixed media artist and I love to cook and make up new recipes. I think I would have chosen to be a chef if I did not love to make art so much. :)
    Thanks again for sharing your wonderful recipes with the rest of us!

  19. Carrie says:

    Hi

    Is there a different replacement for the sugar? Can you use coconut sugar or stevia?

    Thanks… This looks awesome!

    Carrie

  20. This cake looks like a real crowd pleaser! I’d love to make this for a celebration of sorts – wow!

  21. Hi Michelle:

    THanks for your comment. Happy you found the site!

    all best,

    Cybele

  22. HI Carrie:

    I don’t think stevia would work. You can try coconut sugar, but I can’t vouch for it. Try pulverizing it really fine. Not sure if it will perform in the pasty cream though!

    Good luck!

    Cybele

  23. Jesse, I hope you enjoy this cake. It’s one of the best recipes I’ve ever developed, and dangerous to have around too often!

    all best,

    Cybele

  24. Oh my goodness! I love boston cream….this is amazing!!!

    I’m loving your recipes but all I can see instead of amounts is this: �

  27. Heddi says:

    Hello Cybele, I had the same problem as “ash” – coudn’t see the ingredient amounts, but I found a cached version that had them. Also, I had difficulty with the pastry cream, but I think it’s the shortening I used. What brand or type do you usually buy? Thanks so much!

  28. Viv says:

    This Boston Cream Pie Looks Great!!!
    What book is this recipe in so I can find out the ingredient amounts? Thanks, Viv

  29. cybele says:

    Hi Viv:

    I fixed the proportions. It’s all leftover from my hack over a year ago. Sorry!

    Cybele

    Heddi:

    I used Spectrum organic shortening.

      Cybele,

      I just found your site, having newly discovered food allergies (dairy, wheat, and egg) in me and my kids. What a learning adventure! Thanks for being a guide along the way. I can’t wait to try this recipe!! Do you thing Palm Oil Shortening will work in this? I bought some awhile back from Tropical Traditions (love their coconut oil for general cooking), but haven’t tried it in much to discover its characteristics. Do you have any experience with this?

      Jen
