Let's be honest, this isn't really a sundae, since everyone knows that would require ice cream. But it’s so good, calling it a sundae doesn't feel like a stretch. You might be surprised to know that this recipe works best with frozen, not fresh raspberries. They get really juicy when defrosted, which makes a tangy sauce poured over yogurt.
Put the berries into a small glass or ceramic bowl. Microwave on high for 1 minute. If you don’t have a microwave, put in a small saucepan and heat the raspberries on the stove over medium until warm and juicy.
Put the yogurt into another small bowl, like a cereal bowl, and pour the warm berries over the top, followed by the maple syrup. Sprinkle the granola and nuts over the berries. Add the chia seeds and almonds, if desired.
Enjoy with a spoon.
