Pre heat the oven to 430ºF / 220ºc and line a baking sheet with foil.
Place the bacon and jalapenos on the baking sheet and place in the oven for 20-25 minutes until the bacon is well cooked and crispy. Let cool slightly and crumble the bacon and deseed and chop the jalapenos and place to one side.
Mix the flour, baking soda, sugar, salt and pepper in one bowl until combined. To another bowl add the buttermilk, egg and melted butter to another bowl and mix well.
Pour the wet ingredients into the dry and use a whisk to combine. Whisk just until there is no dry mixture left, it will still be lumpy - you don't want a smooth batter.
Add the chopped bacon and jalapeno to the batter and gently fold it all together
Heat the reserved bacon grease in a frying pan on a medium high heat (you can also use butter or oil).
Once the pan is hot, ladle in some of the mixture to the middle of the pan. I used about half a ladle for each pancake.
After about 2-3 minutes, once the bottom of the pancake is bubbling, flip it over with a spatula. Cook for another 2 to 3 minutes until cooked and move to a plate. Repeat until the batter is all used up.
Serve immediately with a pat of butter and maple syrup.
