Begin by preheating your oven to 350°F (175°C) so it reaches the correct temperature before the crackers go in. While the oven is heating, line a baking sheet with parchment paper. This prevents the crackers from sticking to the pan and also makes cleanup much easier after baking.

In a medium mixing bowl, add the almond flour, baking powder, and salt. Use a spoon or small whisk to mix the dry ingredients together thoroughly so the baking powder and salt are evenly distributed throughout the flour. Properly mixing the dry ingredients ensures the crackers bake evenly and develop a consistent texture.

Crack the egg into the bowl with the dry ingredients and pour in the melted butter. Using a spoon or spatula, mix everything together until the ingredients begin to come together and form a soft dough. Continue mixing until there are no dry pockets of flour remaining and the dough becomes smooth and slightly pliable.

Place the dough onto a sheet of parchment paper and cover it with another sheet of parchment paper. Using a rolling pin, gently roll the dough until it becomes thin and even, about the thickness of traditional crackers. Rolling the dough between parchment paper prevents sticking and helps create smooth, evenly rolled crackers.

Once the dough is rolled thin, remove the top sheet of parchment paper. Using a small cookie cutter or a knife, cut the dough into small round or square cracker shapes. Try to keep the shapes evenly sized so they bake at the same rate.

Carefully lift the cut cracker shapes and place them onto the prepared baking sheet lined with parchment paper. Leave a small space between each cracker so the hot air can circulate properly during baking.

Place the baking sheet into the preheated oven and bake the crackers for 12 to 15 minutes. Keep an eye on them during the final minutes of baking. The crackers should turn lightly golden around the edges and become crisp as they finish baking.

Remove the baking sheet from the oven and allow the crackers to cool completely on the tray. As they cool, they will continue to firm up and develop their crunchy texture. Avoid assembling the sandwiches while the crackers are still warm, as they may soften.

While the crackers are cooling, prepare the filling. In a clean mixing bowl, combine the softened cream cheese, shredded cheddar cheese, garlic powder, chopped fresh chives, and chopped turkey bacon. Stir the mixture well until all ingredients are evenly combined and the filling becomes creamy and spreadable.

Once the crackers are fully cooled, take one cracker and spread a small spoonful of the prepared filling onto its surface. Place another cracker on top and gently press it down to form a sandwich. The filling should spread slightly to the edges without spilling out too much.

Continue assembling the sandwiches by repeating the same process with the remaining crackers and filling until everything is used. Arrange the finished cracker sandwiches on a serving plate and they are ready to enjoy as a crispy, creamy low-carb snack.
