Start by greasing a muffin tin with a little oil. Place in the oven and preheat to 425.
In a large bowl add all dry ingredients and mix to combine. Add in the remaining ingredients and whisk until just mixed.
Remove preheated pan and pour batter into muffin tin. Place a slice of jalapeno on top of each muffin and bake for 12-15 minutes or until nice and browned!
