In a medium sized bowl mix together bananas and peanut butter using a hand mixer until combined. Add milk, brown sugar, cinnamon vanilla and flax seed and mix until combined. Stir in oatmeal.
Place bowl in crock pot. Add enough water until is is about 1 inch below the rim of the bowl. Cover crock pot and cook on low for 7-8 hours.
Carefully remove bowl from crock pot. Stir until mixture is combined. Top with sliced bananas and Truvia Brown Sugar Baking Blend.
Notes
Note - You can also put the mixture directly into the crock pot and not use a bowl and water bath, but the sides of the mixture will be crunchy.
