Coconut butter can be very expensive, I found this recipe and am going to try it. No pictures yet but will edit post when I make it and if it turns out ok. Not sure what a Blendtec is but left it in there in case some of you do know.

Ingredients225 grams or 3 cups or more, full-fat unsweetened shredded coconut or coconut flakes or flaked coconut
If using a food processor: fill the food processor at least halfway with coconut flakes. You’ll have a hard time processing if it’s not at least halfway full. Process until very liquidy, almost like water. Stop every few minutes to scrape down the sides and let it cool a little if it feels too warm. Don’t kill your food processor! Depending on your food processor, it could take 15-20 minutes.

If using a Blendtec (you can also use a Vitamix), use the Twister Jar and start processing while twisting the top of the jar counterclockwise. I start off on 1 and work up to about medium power. Process until very liquidy, almost like water. It’ll only take about a minute.

Place in a jar and stir every hour or so until firm and solid (this may take up to 6-8 hours depending on how warm your kitchen is, If you’re in a hurry, refrigerate. Store at room temperature. To soften, place the jar in hot water.
