We're not sure what's better than a chocolate cake with a molten center. It's one of our absolute favorite desserts but this Blueberry Hot Fudge Cake version may just be our best creation yet.
We have a lava cake of sorts already published here on CIK but we thought it was time for a plant-based version with a summer spin. Blueberries and chocolate are one of our favorite fruit/chocolate combos. We typically make this luscious blueberry chocolate pie each summer but this cake may just be our new go-to.
Since this cake doesn't contain eggs, it's even easier to get that ultra gooey center we all love so much as you can underbake the cake as much as you want. We found that 25 minutes is the perfect amount of time for us. 25 minutes yielded a crunchy top and set sides with a molten center that goes perfect with a scoop of vanilla ice cream.
To get the perfect texture, we went with one of our favorite flour combos, Bob's Red Mill Super Fine Almond Flour, Organic Coconut Flour, and Organic Brown Flaxseed Meal. Using both the almond flour and coconut flour together is one of our best tricks to mimic all-purpose flour. The flaxseed makes a perfect egg replacer lending an extra fudgy component to the cake.
If you're wondering if you can use another fruit, we bet this would be equally as awesome with any type of berry. Blackberry is next on our list! Or even maybe a medley of blueberry, raspberry, and blackberry! That sounds just perfect and the best of both all worlds!
