If you want the streusel, start by making that first. Simply throw the ingredients together in a food processor and process until it comes together in small clumps. With you finger, crumble the mixture and scatter on a parchment paper lined baking sheet. Bake at 325 degrees F until golden brown and slightly firm, about 25 minutes, stirring halfway through. After baking, let the streusel cool and then break into smaller pieces. Set aside until ready for use.
For the grapefruit, start by cutting 1/4 inch off the bottom of each half. Then, cut the grapefruit in half and transfer to a parchment paper lined baking sheet, cut side up. Drizzle each grapefruit half with the maple syrup and vanilla. Then, sprinkle each half with the coconut sugar and the spices.
To make it easier to remove the grapefruit from the peel once it’s cooked, use a sharp knife to cut around the edges of the fruit (in between the fruit and the rind). Then gently cut inside the grapefruit, along the edges of the segments. Avoid cutting through the rind.
Broiler the grapefruit halves until the sugar gets bubbly and starts to caramelize, about 3-6 minutes.
Top with optional streusel and cool whip and serve warm. Enjoy!
