Make the dough first. In the bowl of a stand mixer. Add the warm water, it should be around 110 degrees, which is warm to the touch but shouldn't burn your finger.
Then sprinkle in the yeast and brown sugar. Stir, then let the yeast bloom and bubble for about 5 minutes. It should get nice and bubbly.
Now, add the melted vegan butter, cinnamon and salt.
Put the bowl onto the stand and attach the dough hook. Then start adding the flour, add about 1 cup and then add in the blackberry jam.
Using the dough hook to mix and knead, continue to add the flour until it is all incorporated and the dough forms a ball. This may take a few minutes. Let the dough knead for another minute.
Let the dough rest and rise for about 10 minutes. It should puff up a bit.
Now, turn the dough out onto a floured surface and cut into about 8 equal pieces.
Then roll each piece out into a long rope with the palms of your hands. It should be about 20 inches long.
Now, form a U-shape, then holding the ends of the rope, cross them over and under each other and press the ends onto the bottom of the pretzel. I do like to add a dab of vegan egg or water to the ends where they are connecting to the bottom to help the pretzel stay together.
Next, in a large pot, add the 9 cups of water and the baking soda and heat on medium high. Stir and bring to a boil. reduce heat to medium, so it is not at a heavy boil.
Carefully adding 1-2 pretzels at a time, boil for 30-60 seconds. Then place on a baking sheet with a silicone mat or parchment paper lining it. Repeat with all of the pretzels.
Preheat the oven to 400 degrees(F).
While the oven preheats, make the crumble topping. Add all the crumble toppings ingredients to a medium sized mixing bowl. Cut the butter into the dry ingredients with a fork or pastry cutter.
Then pinch and squeeze the butter into the dry ingredients with your fingers until it is evenly distributed and the mixture will hold together easily so you can make crumbles.
Brush the pretzels with the vegan egg and then generously top each pretzels with the crumble topping.
Bake the pretzels for 15 to 20 minutes or until golden brown.
While the pretzels bake, make the icings.
Add the vanilla icing ingredients to a small mixing bowl and whisk to combine. Then do the same with the blackberry icing.
Once the pretzels are done, let cool for a few minutes and then drizzle each pretzel with both icings and then serve!
