Cherry Raspberry Jam Filling 
1 *fyi this may make more than you need so just store any leftovers in an old jam jar
2 In a medium sauce pan, add in one 10 ounce (284 grams) bag of frozen sweet cherries and one 12 ounce (340 grams) bag of frozen raspberries along with 100 grams of granulated sugar and the zest of one orange.
3 Heat over medium heat, stirring frequently until it begins to simmer. Cook until thick and reduced, using a fork along the way to break up the cherries.
4 Pour into a large shallow dish and allow it to cool. Place in the fridge if you're in a hurry, just don't forget to stir it! 
Dough
6 In the bowl of a stand mixer, add in the sugar, orange zest, and cardamom. Rub the zest into the sugar with your fingers to release the oils.
7 Pour in the flour and yeast and whisk it all together.
8 Warm the milk until it is just warm to the touch - it should not exceed 100 degrees F.
9 Add in the warmed milk, egg and egg yolk, butter, salt, and vanilla extract. Knead the mixture with the dough hook on the stand mixer for 20-25 minutes on low speed until it is smooth and the bowl is clean. The dough should stretch and not just snap.
10 Remove the dough and shape it into a ball. Lightly grease the mixing bowl that you were just using and place the ball of dough back in. Then cover the bowl with a towel or plastic and place somewhere warm for 30-45 min. The dough should double in size.
11 At this point, you could also cover the dough with plastic and place it in the fridge overnight.
Shape the Doughnuts
13 After the dough has grown, dump it out onto a lightly floured counter or work surface. Sprinkle the top with flour and use flat hands or a rolling pin to gently press the air out.
14 Roll the dough out into a rectangle that measures about 9" x 12" making sure it's at least 3/4" thick. Try to make the dough as straight and right angled as possible. Use a bench scraper or knife to cut the dough into 12 3" x 3" squares.
15 Place each square onto lightly floured squares of parchment paper. Cover with a sheet of plastic and leave them to rest for 30 minutes somewhere warm to proof.
16 Start heating up 4-5 inches of oil in a large deep pot to 360 F about 10-15 minutes before the squares are finished proofing. This way it will be at the correct temperature when they are ready.
Fry and sugar roll
18 Place a wire rack on a baking sheet and lay 2 layers of paper towel on top of the rack. Fill a wide bowl with granulated sugar to roll the doughnuts in once fried.
19 Once the rolls are proofed, use a slotted spoon or a spider and each square of parchment paper to flip the dough onto the spoon. Lower the proofed dough into the hot oil. Don't fry more than 3 at a time to avoid lowering the temperature more than 10 degrees.
20 Fry them on each side for about 2 minutes - keep an eye on them as 90 seconds may be enough. Use the spoon to carefully flip them over by pressing down on one side. Then fry for another 90-120 seconds.
21 Once they are golden brown, use the slotted spoon to remove them from the oil.
22 Place the fried doughnuts onto the paper towel lined rack to drain off any excess oil. Allow the oil to reheat to 360 F before adding in another batch of doughnuts.
23 Once the next batch is in the oil, roll the first batch in the granulated sugar and place on a separate wire rack to cool.
Vanilla Bean Mascarpone Whip
25 In a medium bowl, add in 250 milliliters cold heavy cream, with 50 grams powdered sugar, a pinch of salt, and vanilla bean paste or crushed vanilla bean.
26 Whip until soft lines form. Spoon in 75 grams of room temperature mascarpone and whip/stir into the cream until smooth and medium/stiff peaks form. Place in the fridge until ready to use. 
Assemble
28 Use a small knife to poke a hole in the side of each doughnut.
29 Fill one piping bag or plastic ziploc with the cream filling and one with the jam.
30 Push the tip of the cream bag into the hole and squeeze the bag gently until the doughnut begins to puff up. Then press the tip of the jam bag into the same opening and pipe it in until each doughnut is full! Sometimes I use the first one as a test and cut it open immediately after to see if I've added enough filling.
31 Enjoy immediately!
