Creating delicious focaccia muffins is a straightforward process. Just follow these easy steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C). Grease a muffin tin with olive oil or line it with muffin liners.
2. Combine Dry Ingredients: In a large bowl, whisk together the all-purpose flour, instant yeast, sugar, salt, garlic powder, and chopped rosemary.
3. Mix Wet Ingredients: In another bowl, combine warm water and olive oil.
4. Combine Mixtures: Gradually pour the wet mixture into the dry ingredients, stirring until a soft dough forms.
5. Knead Dough: Lightly flour a surface and knead the dough for about 2-3 minutes, just until smooth.
6. Let It Rise: Place the dough in a lightly oiled bowl and cover it with a damp cloth. Allow it to rise for about 30 minutes, or until doubled in size.
7. Shape Muffins: After rising, punch down the dough, and divide it into about 12 equal portions. Shape each portion into a ball and place it into the greased muffin tin.
8. Add Cheese: If using cheese, press a little into each muffin and then drizzle with olive oil. Sprinkle sea salt on top.
9. Second Rise: Cover the muffin tin and let the dough rise for an additional 10-15 minutes.
10. Bake: Bake in the preheated oven for 20-25 minutes, or until golden brown on top.
11. Cool: Once baked, remove from the oven and allow the muffins to cool in the tin for about 10 minutes before transferring them to a wire rack.

These steps will lead you to the ultimate in deliciousness with your focaccia muffins.
