Preheat your oven to 350F and line an 8 inch springform pan with parchment paper. Set aside.
Combine the cranberries, orange zest, orange juice, marmalade, and granulated sugar in a pot over medium heat on the stove. Stir and cook until most of the cranberries have burst, then remove from the heat. You don’t want them to get too mushy. Set aside.
To make the streusel: whisk together the sugar, flour, cinnamon, and cardamom. Add the melted butter and mix until thoroughly combined and the mixture resembles wet sand. Set aside while you prepare the cake batter.
Make the cake batter: in a medium-sized bowl, whisk together the flour, baking powder, and salt. Set aside.
In the bowl of a stand mixer fitted with the paddle attachment, or a large bowl if using a handheld mixer, beat the butter and oil - starting at medium speed then gradually bumping it up to high speed. Mix until the butter and oil are completely combined.
With the mixer on low, stream in the granulated sugar, then bump the mixer up to medium-high speed and beat until combined and fluffy, scraping down the bottom and sides of the bowl as necessary.
Add the eggs, one at a time, mixing well on medium-high speed and scraping down the bowl in between each addition. Add the vanilla extract, orange zest & juice and beat until combined.
Add half of the dry ingredients and mix on low until just combined. Add half of the milk and mix on low until just combined. Stop to scrape the bottom and sides of the bowl. Repeat this process with the other halves of the dry ingredients and the milk, being careful not to over-mix.
Spread the batter into an even layer in your pan. Sprinkle the cranberries in an even layer on top of the batter, followed by the streusel.
Bake for 50-65 minutes until golden brown and a toothpick inserted into the center of the cake comes out clean. All overs differ - if you want, begin checking at around 45 minutes, just to be sure. The center of the cake should not jiggle and the cake should be slightly peeling away from the edges of the pan.
To enjoy the cake slightly warm, let it cool for at least 30 minutes in the pan. Otherwise, let it cool completely in the pan. Store in an airtight container at room temperature or in the fridge. Enjoy!
