Follow these simple steps to bring a bit of Devon warmth into your home:

1. Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish.
2. In a large bowl, mix the flour, granulated sugar, baking powder, baking soda, and salt. Stir well to combine.
3. In a separate bowl, whisk together the melted butter, pumpkin puree, buttermilk, eggs, vanilla extract, and honey until smooth.
4. Gradually add the wet ingredients to the dry ingredients, mixing gently until just combined. Be careful not to overmix, as this can make the cake dense.
5. In a small bowl, combine the brown sugar and cinnamon. Pour half of the cake batter into the prepared baking dish, then sprinkle the cinnamon-sugar mixture evenly over the top.
6. Pour the remaining batter over the cinnamon-sugar layer, spreading it gently to cover.
7. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool slightly before serving.

A tip from my mum: if you want a little extra indulgence, drizzle a simple glaze of powdered sugar and milk over the warm cake.
