1. Prepare the Yogurt Mixture: In a medium bowl, combine the plain Greek yogurt, honey (or maple syrup), and vanilla extract. Stir well until all ingredients are thoroughly mixed and the sweetener is fully incorporated. The mixture should be smooth and creamy.

2. Layer the Red: Begin by spooning a layer of the diced strawberries into the bottom of each popsicle mold. Aim for about 1/4 to 1/3 of the mold’s capacity, creating a distinct red layer. Gently press the strawberries down to ensure an even base.

3. Add the White Layer: Carefully spoon the prepared yogurt mixture over the strawberry layer in each mold. Fill the mold about two-thirds full, ensuring the yogurt completely covers the strawberries. Use the back of a spoon to gently smooth the top of the yogurt layer.

4. Introduce the Blue Layer: Sprinkle a generous amount of fresh blueberries on top of the yogurt layer in each mold. Fill the remaining space in the mold with the blueberries, leaving a small gap at the very top for expansion during freezing.

5. Insert Popsicle Sticks: Carefully insert a popsicle stick into the center of each mold, pushing it down through the blueberries and yogurt until it’s firmly in place. Make sure the stick is straight.

6. Freeze Until Solid: Place the filled popsicle molds upright in the freezer. Allow them to freeze for at least 4-6 hours, or preferably overnight, until they are completely solid. This ensures they hold their shape perfectly when removed.

7. Serve and Enjoy: Once frozen, remove the pops from the molds. If they are difficult to release, run the molds under warm water for a few seconds (be careful not to melt the pop) until they slide out easily. Serve immediately and enjoy your patriotic treat!
