In a medium sized bowl combine the cocoa powder, 1/3 cup of sugar and the hot water. Stir well to combine and set aside.
In another small bowl combine the flour, baking powder, vanilla powder and salt. Whisk until well combined.
In the large bowl of a stand mixer, beat together the remaining sugar (2 cups) and the eggs until well combined. Slowly pour in the olive oil and continue to mix.
With the speed set to low, carefully add 1/2 of the flour mixture to the oil/egg/sugar combination in the stand mixer. Beat until well combined. Pour in 1/2 cup of milk. Continue beating and then add the remaining flour, followed by the remaining 1/2 cup of milk. Scrape down the sides of the bowl using a rubber spatula and then beat well for a minute until all of the ingredients are well combined.
Remove approximately 3 cups of this cake batter and add half of it (about 1 1/5 cups) to the bowl which contains the cocoa powder, sugar and water. Using a whisk, mix it well by hand so that all of the plain batter is combined with the cocoa batter.
Take the other 1 1/2 cup batter which you removed from the stand mixer bowl and combine it with the strawberry jam. Using a whisk mix it well by hand so that all of the plain batter is combined with the strawberry jam.
Grease a bundt pan. Pour enough of the plain batter into the pan to cover the bottom surface. Then, using a large spoon, drop spoonfuls of the cocoa batter on top of the plain batter. Leave approximately 1/3 of the cocoa batter in the bowl. Next, drop spoonfuls of the strawberry batter into the cake pan, leaving approximately 1/3 of the strawberry batter in the bowl.
Pour the remaining vanilla batter into the bundt pan, and then pour in the rest of the cocoa batter and strawberry batter.
Bake in the middle rack of your oven for 50 – 60 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the bundt pan for approximately 5 minutes before removing it. Set it to cool on a baking rack.
