Begin by combining the strawberries, sugar, vinegar, and vanilla in a medium-sized pot over medium-high heat. Let simmer until sugar dissolves, stirring occasionally. After 4-5 minutes, remove from heat and let cool so that sauce thickens. Set aside.
Whisk together all the ingredients (except for the bread) into a large bowl and set aside so that everything marries together and activates, about 5 minutes.
Preheat griddle to medium-high heat and add 1 Tbsp of vegan butter, melting it.
Also, preheat oven to 400 degrees Fahrenheit and prep a large baking sheet by lining with parchment paper.
Dip 1 slice of bread into the batter, soaking it in for a few seconds on each side. Place slice unto the heated griddle, cooking on each side for about 3-4 minutes until golden brown. Repeat until all french toast has been made.
Once done, add all french toast onto baking sheet (side by side) and bake for 10-15 minutes until crisp on the edges. Remove and serve.
To serve—stack french toast atop each other, spoon a generous amount of balsamic glazed strawberries and drizzle with date pure maple syrup, if desired.
