Dry fruits: Line a tray with paper towels or a tea towel, then place pineapple and cherries on. Pat dry with paper towels.
Butter: Pour melted butter into a 23cm/9"cake pan at least 5cm/2" deep. (Not springform, as they'll leak.) Brush butter up the sides.
Brown sugar: Sprinkle sugar over the base, roughly spreading it out (use the brush).
Arrange pineapple: Place one pineapple ring in the center, then surround with either halved pine apple rings (as pictured), or whole ones
Decorate with cherries as desired. Most people just put them in the middle of the pineapple rings.
Press cherries and pineapples down firmly so they are in direct contact with the base of the cakepan - so you get vibrant red and yellow color pops at the end, not tarnished by caramel. (Note 5)
Batter
Flour Mixture: Whisk flour, baking powder, baking soda and salt in a bowl.
Milk Mixture: Whisk milk, sour cream, pineapple uice and vanilla in a 2nd bowl.
Cream butter and sugar: In a third (final!)bowl, beat the butter and sugar for 2 minutes on speed 7 (handheld mixer) until fluffy.
Eggs: Add eggs one at a time, beating for 20 seconds in between.
Add Flour Mixture then Milk Mixture, alternating: Add 1/3 of the Flour Mixture, then mix in using a rubber spatula. Add 1/2 the Milk Mixture, mix in. Add half the remaining Flour Mixture, mix.
Add all the remaining Milk Mixture, mix. Then mix in the last of the Flour Mixture. Stir in the leftover pineapple pieces.
Fill pan: Spread batter over pineapple layer, smooth and level the surface.
Bake: Bake for 30 minutes. Remove, loosely cover with foil, then bake for a further 15 minutes until a toothpick inserted into the center comes out clean.
Turning Out Cake
Cool 20 minutes: Remove cake from oven and leave inside pan to cool for 20 minutes.
Flip! Run a butter knife around the inner edge of the cake pan. Put a plate or serving platter over the cake, then flip. Tap base / shake pan gently then lift slowly. Voila!
Cool completely before serving.
Incorporating Pellet Grill instructions:
When ready to cook, start temperature to 350 degrees F and preheat, lid closed, for 10 to 15 minutes.
Place the cast iron pan on the grill grate and cook for 20 minutes. Rotate the pan a half turn to ensure it cooks evenly. Cook for an additional 20 minutes, or until toothpick inserted in center comes out clean.
Immediately run knife around side of pan to loosen cake. Place heatproof serving plate upside down onto pan; turn plate and pan over. 6. Leave pan over cake 5 minutes so brown sugar topping can drizzle over cake. Cool 30 minutes. Enjoy!
