In a mixing bowl, combine the warm water, honey (or maple syrup), and apple cider vinegar. Stir until the honey dissolves.
Add the instant yeast to the warm water mixture and let it sit for about 5-10 minutes, until it becomes frothy.
In a separate bowl, whisk together the gluten-free all-purpose flour, salt, and baking powder.
Once the yeast mixture is frothy, add the olive oil and mix well.
Gradually add the dry ingredients to the wet ingredients, using a spatula to combine until a sticky dough forms. Do not over-mix.
Transfer the dough into a greased bread pan, smoothing the top with the spatula.
Cover the bread pan with a clean kitchen towel and let the dough rise in a warm place for about 30-40 minutes, or until it has doubled in size.
Preheat the oven to 375°F (190°C) while the dough is rising.
Once the dough has risen, bake in the preheated oven for 40-50 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Allow the bread to cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely before slicing.
