Preheat oven to 350F. Butter a 9 in bundt cake pan.
In a medium bowl, beat the butter and erythritol until fluffy, approx 1 minute.
Add eggs one at a time to the butter mixture and incorporate using an electric hand mixer. Add the vanilla extract, orange extract and orange zest and mix.
Add the almond flour, and baking powder to the butter mixture and mix until well incorporated.
Spoon mixture into the greased bundt pan and level with a spatula. Bake for 30 mins or until inserted toothpick comes out clean.
Place bundt pan on a cooling rack and allow to cool approx 10 minutes. Using a butter knife gently loosen cake around the edges and around inside ring. Gently invert cake onto cooling rack and allow to cool completely.
Melt the chocolate chips and heavy cream in a microwave safe dish in 10 second intervals until shiny and completely melted. Spoon into a small ziplock back, cut corner off and drizzle over the bundt care.
