In a mixing bowl, combine the lukewarm water, granulated sugar, honey, and instant dry yeast. Stir gently and let it sit for about 5-10 minutes until it becomes frothy.
Once the yeast mixture is frothy, add the vegetable oil, salt, and 2 cups of all-purpose flour. Stir to combine, then gradually add the remaining flour until a soft dough forms.
Turn the dough onto a floured countertop and knead for about 5 minutes, adding flour as necessary, until the dough is smooth and elastic.
Shape the dough into a ball and place it back in the mixing bowl. Cover it with a kitchen towel and let it rise in a warm place for about 1 hour, or until it has doubled in size.
Grease the inside of the slow cooker with non-stick cooking spray or olive oil.
Once the dough has risen, punch it down to release air. Shape it into a loaf and place it in the slow cooker. Cover with the lid and cook on high for 2-3 hours.
When done, carefully remove the bread from the slow cooker and let it cool on a wire rack. Slice and enjoy your delicious Slow Cooker Bread!
