Place medium mixing bowl for whipped cream in freezer.
Preheat oven to 350°. In small mixing bowl toss coconut chips with coconut oil and salt. Spread evenly on baking sheet lined with parchment paper or baking mat and bake for 5-8 minutes until golden brown. Remove from oven and set aside.
In a skillet over medium high heat melt coconut oil. Add pineapple chunks and mix. Mix in brown sugar and rum. Keep on medium high heat for 5-6 minutes until sauce starts to bubble and thicken. Remove from heat and set aside.
In a large mixing bowl add flour, baking powder and salt. In a separate bowl add your room temperature eggs and brown sugar and whisk. Add yogurt, rum, pineapple juice and vanilla and mix thoroughly.
Add wet ingredients to your dry ingredients in increments, mixing after each pour. Mix just until combined. Careful not to over-mix.
Grease a 9x13 baking dish or two 8 inch cake pans. Pour batter into your pan(s). Place cake in oven for 40-45 minutes until golden brown and tooth pick comes out clean.
Take your mixing bowl out of the freezer and your can of coconut cream from the fridge. Scoop your coconut cream from your can into your mixing bowl. ( Save the water in the bottom of the can to add to smoothies later!). Add brown sugar, rum and sweetener to bowl and mix on medium/high for 2-3 minutes until you achieve a light and airy consistency. You can use either a stand mixer or hand mixed for this step. Keep cream in refrigerator until you are ready to add it to your cake.
Once your cake is ready allow it to completely cool. Once cooled, top your cake with your whipped coconut cream, pineapples and coconut chips. Take a bite and enjoy a little slice of paradise!
