Preheat the oven to 350 degrees F.
Whisk together the eggs, butter, Swerve sweetener, and vanilla.
Add the cream cheese and beat with an electric hand mixer until well incorporated.
Mix in the flours, psyllium husk powder, and baking powder until well combined. Set aside.
Combine filling ingredients (cinnamon, Swerve, melted butter) in a small bowl.
Layer cake batter, filling, then cake batter into a greased Bundt pan.
*Optional: add a baby into the batter.
Bake in the oven for 30 – 35 minutes until it begins to brown on top.
While the cake is baking, make icing by combining all ingredients until smooth and creamy.
Once the cake is completely cooled, top it with the frosting and add colorful sprinkles.
Enjoy!
