First, preheat your oven to 325 degrees F.
Next, line your 9 inch cake pan or 9 inch springform pan with a round piece of parchment paper. Also, spray it well with olive oil to ensure the cake doesn't stick. Set the cake pan aside.
In a stand mixer with the whisk attachment (or a handheld mixer) beat together eggs, olive oil, sugar, honey, vanilla, orange zest and orange juice for about 1 minute.
Next, add in the almond flour, tapioca flour, coconut flour and baking powder. Beat until incorporated.
Pour the cake batter into the prepared cake pan.
Bake at 325 degrees F for 28-30 minutes.
If the cake is browning too quickly, open the oven and place an aluminum foil dome/tent over the top of the cake and continue to let it bake. This can happen with almond flour.
I placed foil over the top when there was about 10-12 minutes left. Just make sure you don't place the foil straight on top of the cake or it could make a dent in the cake. It's important to dome/tent the foil.
Remove the cake from the oven and place it on a wire cooling rack for 10-15 minutes.
Then, use a butter knife to gently remove the cake from the pan, peel back the parchment paper and place the cake on the wire rack to cool completely.
I recommend adding powdered sugar and orange zest on top of the cake before slicing.
