In a medium bowl, whisk together the whole wheat flour, sugar, baking powder, baking soda, salt, and cinnamon. Set aside.
In another bowl, combine the buttermilk, canola oil, egg whites, vanilla extract, lemon zest, and lemon juice. Whisk until everything is well incorporated.
Pour the wet ingredients over the dry ingredients, and stir gently with a spatula until just combined. Be careful not to over-mix; the batter should be thick and lumpy.
Heat a griddle pan or non-stick skillet over medium heat. Once hot, spray it lightly with cooking spray to prevent sticking. Pour about 1/4 cup of pancake batter onto the hot griddle.
Carefully flip the pancakes and cook until they’re lightly browned on the other side.
To prepare the compote, spray a medium skillet with cooking spray and add the chopped rhubarb. Cook over medium heat for about 2 to 3 minutes until it starts to soften.
Next, add in the honey, lemon zest, and lemon juice. Stir this mixture and cook for another two minutes.
Finally, stir in the strawberries and cook for another two minutes until they’re heated through and everything is well combined.
Serve the warm strawberry rhubarb compote generously over the hot pancakes. Enjoy your delightful breakfast!
