Poke Cake

  • cups almond flour
  • cups coconut flour
  • 2 tbsp arrowroot starch
  • tbsp baking powder
  • tsp baking soda
  • tsp xanthan gum
  • ½ tsp nutmeg optional
  • ¼ tsp salted butter ½ tsp if you use unsalted butter
  • 1 cup salted butter softened
  • 1 cup granulated monkfruit erythritol sweetener plus 2 tbsp
  • 1 cup light unsweetened coconut milk or vanilla unsweetened almond milk  you can also use light or heavy cream for a richer cake
  • 1 tsp white vinegar
  • 4 egg yolks seperated
  • tsp vanilla extract

Boston Cream Filling

Chocolate Glaze

  • 1 cup stevia sweetened chocolate chips
  • 1 cup heavy cream
  • 1 tbsp butter


  • Pre-heat oven to 350°F.
  • In a bowl, whisk together your dry ingredients including; almond flour, arrowroot starch, baking powder, baking soda, nutmeg and salt.
  • In a measuring cup or small bowl, add your coconut milk and vinegar and set aside.
  • In another very large bowl, beat together the butter and sweetener until light and fluffy (~2 min) then add your egg yolks and vanilla extract and beat again until smooth.
  • Finally, in another bowl, beat your egg whites until the turn pretty much solid white in color.
  • Add your dry ingredients as well as the cream/vinegar to the beaten butter and sugar mixture. Mix well until no flour is left visible and a thick dough forms.
  • Gently stir in the egg whites until no longer visible.
  • Press the cake into the bottom of a greased 9×13 inch pan.
  • bake for 23-27min or until golden brown around the edges and a toothpick comes out clean.
  • Once the cake is fully cooled, poke holes throughout it using the opposite end of a wooden spoon (see photo for reference). Poke all the way to the bottom of the cake.
  • You can then make the pudding simply by adding the dry mix to a bowl and beating with the cream and coconut milk until it just starts to thicken (don't over-beat it). You want it still liquid enough to be able to pour into the holes in the cake.
  • Use a spatula to spread the mixture over the top of the cake a few times to fill the holes and form an even layer.
  • Refrigerate for 30-40min.
  • After refrigeration, you can make your chocolate topping by microwaving the heavy cream in a large glass measuring cup or bowl until hot (~1min – 1min 30s).
  • Add your chocolate chips and butter to the hot cream and leave for 40 seconds before mixing well until everything is melted, silky and the mixture is a dark brown color.
  • Pour the mixture as evenly over the cake as you can, then use a spatula to even it out.
  • Refrigerate the whole cake again for at least 30-45min before slicing and serving. Enjoy your Keto Boston Cream Poke Cake!
  • Pro tip: once the cake has chilled and set, I actually like serving it at room temperature or heated for just 15-20s in the microwave to take the chill off. It gets so much softer!
