Per the usual with cake recipes of this nature, you’re going to want to start off by meandering over to your trusty oven, and preheating it to 350°.
As that warms up, you can take this time to thoroughly grease and flour a nearby pan. I’d say aim to use one that’s 9” x 13” in dimension.
Then, you’ll want to grab a saucepan. In it, mix together your water and raisins. When you feel like those two elements are intricately incorporated with one another, bring the contents to a solid boil, and keep it in that boiling state for roughly 10 minutes.
When that time period is up, remove the saucepan from the heat source, and toss in your brown sugar, white sugar, and cannabis-infused butter. Be mindful to adequately stir up these ingredients to the best of your ability, as that will help everything cool down after being boiled.
Following that, in a large mixing bowl, combine your salt, baking soda, cinnamon, and flour. When you’re happy with how those ingredients are blended together, you can then toss in your nuts and raisin mixture. Again, stir everything up until the entirety of the contents develop a super smooth consistency and texture.
At this point, you can pour that delicious, delicious batter into that previously greased and floured pan.
If your oven has reached that 350° temperature mark, you can toss the batter in to bake for a little over 40 minutes. You’ll know it is ready to be taken out when it passes that tried-and-true “toothpick test of done-ness.”
Once that happens, simply remove the cake from the oven, and slice it into 2 dozen equally-sized portions, pick out your favorite one, and have at it!
