1/2 cup butter, room temperature
1 cup brown sugar
1 cup all purpose flour
1 tsp baking powder
1/2 tsp salt
1/2 cup rolled oats, whole or quick cooking
1/2 cup shredded coconut, sweetened or unsweetened
1 14-oz can sweetened condensed milk
1/2 cup fresh lime juice
2 tsp lime zest
Preheat oven to 350F. Line a 9×9-inch baking pan with aluminum foil and grease lightly.
In a large bowl, cream together butter and brown sugar until fluffy. Add in flour, baking powder and salt and mix until everything comes together in a crumbly mixture and flour is evenly distributed. Mix in oats and coconut. Mixture will be somewhat dry and sandy.
Put 2 cups of the oat mixture into the bottom of prepared baking dish and press firmly into an even layer. Pour lime mixture on top and spread evenly. Crumble all remaining oat mixture over the top of the lime mixture, covering it completely.
Bake for 30-35 minutes, until golden brown.
