I used home made vanilla essence made from vanilla pods and vodka. Here's the recipe I followed.
Coconut Oatmeal Cookies - Adapted from Darlene's Recipe at allrecipes.com
1 Cup Unsalted Butter (227g)
1 Cup Brown Sugar
1 Cup Refined White Sugar
1 1/2 Tsp Vanilla Essence
2 Cups AP Flour
1 Cup Coconut Flakes
2 Cups Rolled Oats + as much more as you think you can add to it.*
1/2 Tsp Sea Salt
1 Tsp Baking Soda
1 Tsp Baking Powder
*I probably used 1/4 - 1/2 cup more. Stir in a little bit at a time, making sure you can still make balls out of the batter. You don't want to add so much more that the batter is dry and falls apart. The amount of extra oatmeal you can add will probably depend on the size of your eggs.
Step 1: Preheat oven to 175C (350F).
Step 2: Mix butter and sugars. Then add eggs and vanilla essence until thoroughly mixed.
Step 3: In another bowl, mix the flour, salt, baking power and baking soda. Whisk vigorously so that everything is mixed and sifted. Then add the oats and mix some more. Then add the coconut and mix lightly.
Step 4: Add the dry ingredients into the wet ingredients 1 cup at a time and blend. Try to do this as quickly as you can.
Step 5: Make small balls with your hands and press them down a bit to flatten with the palms of your hands.
Step 6: Bake for 12 minutes or until golden brown.
