Add almond milk, coconut oil, lemon zest, and flaxseeds in a bowl, and mix well.
In a large bowl, add brown rice flour, almond flour, baking powder, sugar, salt, and mix well.
Pour the wet ingredients into the dry ingredients and gently mix.
Fold in raspberries lightly.
Pour the batter into an 8-inch greased Bundt pan and place the baking pan in a preheated oven at 350 degrees F for 50-60 minutes.
Once the cake is made, insert the toothpick. If it comes out clean, remove the cake from the oven, and after 15 minutes, invert it onto a cooling rack or a serving plate to finish cooling.
Let the cake cool down completely before adding the frosting.
