French Gâteau Marbré - Marble Cake

Method

1. 1
   Preheat the oven to 350°F / 180°C. Line a loaf pan with parchment paper.
2. 2
   In a large bowl, whisk together the melted butter, sugar, eggs, milk, whipping cream, canola oil and vanilla until fluffy and combined. This gives you a lovely rise.
3. 3
   Add the flour, baking powder and salt. Mix just until combined - don't overmix!
4. 4
   Divide the batter between two bowls. It doesn’t need to be perfectly even. Add the cocoa powder to one bowl and mix until fully incorporated.
5. 5
   Alternate spoonfuls of the vanilla and chocolate batters into the prepared loaf pan. You can gently swirl the two batters together with a knife for a marbled effect. Place a few small pieces of butter down the center of the top of the batter.
6. 6
   Bake for about 50 minutes, or until a knife inserted into the center comes out clean. Let cool before slicing.
