Chef's pro tip
When our cake turns out dry and crumbly, it's like a major party foul, right? But no worries, we've got this. Let's kick things off by getting super exact with that almond flour measurement. And hey, show your batter some love—overmixing is just not cool. Our secret weapon? A dash of extra moisture! Something like pumpkin puree or unsweetened hemp milk does the trick. Ready to dig into your uber-moist, spice-hitting-all-the-right-notes, keto pumpkin spice cake? It's about to make your taste buds do a happy dance!

Dee Mack says
Can I use Cashew or Almond Milk instead of the Hemp?
Alex Lester says
Yes!
Jo Vernon says
what can i use in a recipe instead of Pacific Foods Unsweetened Hemp Original Beverage
Alex Lester says
You can use any type of milk or even heavy cream.
Terra Romero says
Would this turn out ok with coconut almond milk as a sub for the hemp beverage? im guessing the hemp beverage is rather thick being it has 19 carbs per cup.
Cast Iron Keto says
Hi Terra, it should work just fine. The hemp beverage isn't any thicker than any other type of non-dairy milk.
