In a bowl, mix together the cake batter base ingredients: cashew butter, almond flour, almond extract, and maple syrup. If your cashew butter is on the thicker side, add a little more maple syrup or liquid until it comes together. Mine was pretty runny to start.
Dollop about 1 tsp of the batter mixture into each cavity of a mini muffin tin (I use silicone for easy removal). Top each with a banana slice.
Cover with 1–2 tsp vanilla yogurt. Tap the pan on the counter to help everything settle and flatten out.
Sprinkle with hemp seeds and sprinkles.
Freeze until solid (2-4 hours minimum), then pop them out and enjoy. (Let sit at room temperature for 2–3 minutes to soften slightly before eating.)
