Happy Friday, my friends! Are you ready for the weekend? I know I am, it’s been a verrrrrry busy week, and I’m so looking forward to kicking back with some friends.
We’re thinking about doing a little bonfire on Saturday night. I’m thinking it will be so chill and relaxing, just hanging out on the back patio under some cozy blankets, looking at the fire with a glass of wine. Don’t you just love fall? I’m not sorry to see fall begin but let’s not talk about winter 😉
Of course, with fall comes pumpkin desserts, and this is one you’ve just gotta try!
It’s inspired by the iconic Boston cream pie, but really it bears little resemblance. The sponge cake has been replaced with a spiced pumpkin cake. It’s a lot more moist than the traditional sponge, and I’m not so sure that’s a bad thing! The custard is sweetened with maple syrup, and ermahgerd, you guys- the GANACHE! Make this cake for the ganache alone, I’m telling you! I’ve never tasted anything quite like and and it completely makes the whole cake.
Ok so we need to talk about caramelized white chocolate. It’s a thing! I’ve been seeing it more and more, but it was Graham’s description that convinced me to finally give it a go. Basically, you just bake the white chocolate in the oven, at a really low temp, for 40 minutes. It’s kind of a pain in the neck, but you’ve gotta stir it every 5. And you will probably be convinced that you’re doing it wrong the whole time. I was! I was all “there’s no way this is gonna work.” But it totally worked! It goes from looking all seized and hard and lumpy, to somehow magically liquefied, smooth, and caramelized. Then we stir in some cream and pour it over the cake. Then we swoon. Then we do a happy dance!
To. Die. For. Wow. So toasty and sweet, almost like butterscotch but with that distinctive white chocolate richness. I’m in love.

- 2 cups all-purpose flour
- 3/4 cups granulated sugar
- 1/4 cup brown sugar
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon ground ginger
- 12 tablespoons unsalted butter (1 1/2 sticks), softened
- 4 eggs (large)
- 2/3 cup pumpkin puree
- 1/3 cup Greek yogurt
- 2 teaspoons vanilla extract
- 8 ounces white chocolate
- 1/3 cup heavy cream
- Pour the milk into a small pot and place over medium heat until small bubbles form around the edges.
- In a medium mixing bowl, whisk the egg yolks with the maple syrup, cornstarch, and salt.
- Slowly pour the hot milk over the egg mixture, while whisking, to warm the eggs.
- Place the mixture back into the pot and place over low heat. Cook, stirring constantly, until the mixture comes to a bubble and becomes very thick.
- Stir in the vanilla and transfer to a heat safe container. Lay plastic wrap over the surface. Chill for 2 hours.
Preheat the oven to 325 degrees F and mist (3) 6-inch cake pans with non-stick spray.
- Place the flour, sugars, baking powder, salt, and spices in a large mixing bowl and whisk to combine.
- Add the soft butter, and mix on low speed until the mixture resembles wet sand.
- Stir in the eggs, one at a time, scraping the bottom and sides of the bowl with a silicone spatula after each addition.
- Add the pumpkin, Greek yogurt, and vanilla, and mix on medium-low speed for about 90 seconds, to aerate the batter and develop the cake's structure.
- Bake for 40-45 minutes, or until a tester inserted in the middle of the cake comes out clean or with a few moist crumbs. Cool completely and fill with pastry cream.
- Preheat the oven to 265 degrees F.
- Break up the white chocolate into pieces, and scatter in the bottom of a baking dish (I used a 9x13 glass dish).
- Bake in the oven for 40 minutes, stirring every 5 minutes. Chocolate will become thick and chalky.
- After 40 minutes, remove from the oven and transfer to a bowl. Stir until the chocolate becomes liquefied.
- Heat the cream until small bubbles form around the edges. Pour the hot cream over the caramelized white chocolate. Whisk to combine.
- Allow to cool slightly, then pour over the cake, using a metal spatula to spread in an even layer.
