The Cake Slice October 2010: Pumpkin (Sweet Potato) Chocolate Chip Pound Cake (GF)

I’m so excited to be able to reveal that the new cake book that The Cake Slice bakers will be baking from for the next year is…. Cake Keeper Cakes by Lauren Chattman! It’s a fantastic looking book and absolutely full of all sorts of different types and styles of cakes – not just layer cakes, but loaf cakes, bundt cakes and snacking cakes to name but a few. If they are half as good as this months debut cake then we are going to be in for a treat!

The winning cake from our new cake book was a pumpkin chocolate chip loaf cake, which I was delighted about considering how seasonal it is. The recipe calls for canned pumpkin puree, but it is near impossible to find pumpkin puree in this country and so I substituted this with some pureed sweet potato. This worked really well and resulted in a deliciously moist and tender cake that had a faint pleasing orange colour.

I actually made this cake just a few days after discovering I had to go gluten free and so it was my very first attempt at baking. I decided to substitute the flour for Buckwheat flour, which despite its name is gluten free. This has a subtle nutty grassy flavour to it, similar to rye flour, and a natural sweetness that I thought would go well with the chocolate chips and sweet potato elements of the cake.

The recipe made a lot of cake mix and I was worried there would be too much for the tin but it baked up fine, tall and puffy with a long crack down one side which I actually think improved the appearance as it gave a tempting insight into the melty chocolate chips hidden within.

I absolutely loved the results and would never have guessed it was gluten free. It was light, soft and springy and wonderfully moist. I loved the dark chocolate chips studded throughout the cake which seemed to stay permanently soft and slightly gooey after baking. I couldn’t stop eating it and bizarrely it tasted really good when dipped into hot strong coffee.

Unfortunately the rest of my family had mixed results to this cake. My mum ate it and said it was ok, but she didn’t like the grassy note from the buckwheat. My dad was not a fan but he likes more traditional flavours and was highly confused by the combination of spices, sweet potato and chocolate chips in a cake. However, my lovely grandmother (who shares/shared my tastes for rye breads and other assorted grains) adored the cake as much as I did. She even said that if that’s what gluten free cake tasted like then she wouldn’t mind binning wheat altogether – I love you grandma!

I know that other members of the group loved this cake too, so gluten free or not, this autumnal cake is perfect for this time of year and definitely worth making. Click to see the Cake Slice blogroll.

Pumpkin (Sweet Potato) Chocolate Chip Pound Cake (GF)(Recipe from Cake Keeper Cakes by Lauren Chattman)

Ingredients

210g plain flour (I used Doves buckwheat flour)
1 tsp baking soda

1 tsp baking powder

1 tsp ground cinnamon

½ tsp salt

¼ tsp ground cloves

Pinch nutmeg

100g unsalted butter, softened

280g caster sugar

3 eggs

200g pumpkin puree (I used pureed sweet potato*)

1 tsp vanilla extract

75ml milk

75g dark chocolate chips

75g chopped walnuts (I’d run out of these)

MethodHeat the oven to 180C. Coat the inside of a 9 x 5 inch loaf pan with nonstick cooking spray and dust with flour.

Combine the flour, baking powder, baking soda, cinnamon, salt, cloves and nutmeg in a medium mixing bowl.

Combine the butter and sugar in a large mixing bowl and cream with an electric mixer on medium high speed until fluffy, about 3 minutes, scraping down the sides of the bowl once or twice as necessary.

With the mixer on medium low speed, add the eggs, one at a time, scraping down the sides of the bowl after each addition. Stir in the pumpkin puree (see note below) and vanilla. Stir in the milk.

Turn the mixer to low speed and add the flour mixture, a third at a time, scraping down the sides of the bowl after each addition. Stir in the chocolate chips and walnuts.

Scrape the batter into the prepared pan and smooth the top with a rubber spatula. Bake the cake until it is firm to the touch and a toothpick inserted in the centre comes out clean, 55 minutes to 1 hour. Let the cake cool in the pan for 5 minutes, invert it onto a wire rack and then turn it right side up on a rack to cool completely.

Store uneaten cake in a cake keeper at room temperature for up to 3 days or in the refrigerator, wrapped in plastic for up to 1 week.

Makes one 9 by 5 inch loaf cake

Note* It’s very hard to find pumpkin puree in the UK, so I substituted this with homemade sweet potato puree. Simply cut a large sweet potato in half, place in a bowl and add 2tbsp water. Cover the top with clingfilm and microwave on high for 7 minutes until the flesh is soft. Scoop out the flesh and mash with a potato masher (you won’t need to add any liquid or butter) and use as above.
