If you'd like to be absolutely sure that you have an even amount of batter in both pans, you can weigh them using a food scale, which is what I like to do.
Bake for 15-18 minutes or until a toothpick, when inserted comes out clean. Allow to cool completely before frosting.
To Make the Whipped Topping and Filling
Add the heavy cream into a large mixing bowl and mix using a hand mixer until soft peaks are formed.
Add in the mascarone in small dollops, monk fruit/allulose and vanilla extract and continue mixing until well combined and thickened. Chill in the fridge until you the cakes have cooled.
To Assemble the Cake
Take one of the cakes and place it on a cake stand or plate. Add half of the whipped topping over the top and spread evenly using an offset spatula.
Add half of the strawberries on top, then repeat with the second layer. You can add the strawberries on the top layer in a decorative pattern, just to make it look extra special.
Notes
Oat Fiber is made from grinding the outer husks of oats. How healthy is oat fiber? It's pure insoluble fiber, which doesn't dissolve in water and isn't broken down in the digestive tract, so it has zero net carbs and is perfect for a Keto Diet. It helps give a more traditional texture and that's why I use it so often. Check out all the Keto Oat Fiber Recipes you can make!To get the best results, it's best to use oat fiber if you can. If you're unable to find it, try a combination of psyllium husk powder and coconut flour. Since both are very absorbent, you might have to add more liquid.
