Creating Healthy Pumpkin Cheesecake Bars is easy if you follow these straightforward steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Prepare a square baking dish (8×8-inch works well) by greasing it or lining it with parchment paper.
2. Make the Base: In a medium bowl, mix the rolled oats, almond flour, melted coconut oil, maple syrup, vanilla extract, cinnamon, nutmeg, and salt until well combined.
3. Press the Mixture: Press this oat mixture evenly into the bottom of the prepared baking dish to form the crust.
4. Bake the Crust: Place the crust in the preheated oven and bake for about 10 minutes. Remove and let it cool slightly.
5. Prepare the Filling: In a large mixing bowl, combine the pumpkin puree, Greek yogurt, brown sugar, eggs, pumpkin spice, and baking powder. Mix until smooth and thoroughly combined.
6. Spread the Filling: Pour the pumpkin cheesecake filling over the cooled oat crust. Spread it evenly.
7. Bake Again: Return the dish to the oven and bake for an additional 25-30 minutes or until the filling is set and appears firm.
8. Cool the Bars: Remove from the oven and allow the bars to cool at room temperature for about 30 minutes. Once cooled, refrigerate for at least 1 hour to fully set.
9. Slice the Bars: Once chilled and set, cut into squares or rectangle bars.
10. Serve and Enjoy: These bars can be enjoyed chilled, at room temperature, or warmed slightly in the microwave.
