These are delicious muffins perfect for the summer! They are soft and light, with tangy rhubarb flavour and sweet strawberries throughout. They have a sweet sugar streusel sprinkled on top too.
Line a 12 tin muffin liner with 12 liners or 2 liners with 6 muffin tins in each (Your preference) and set aside. Roughly chop the strawberries and rhubarb and set aside.
In a small bowl, make the streusel. Combine flour, white sugar, and cold cut up butter. Using your hands, mix it together until combined into a crumbly, streusel mixture. Set aside while you make the muffin batter.
3/4 cups all-purpose flour, 1/3 cup white sugar, 6 tbsp butter
In a medium-sized bowl, add the flour, baking powder, vanilla pudding powder, baking soda, and salt. Mix together and set aside.
In a large bowl, add oil, buttermilk, vanilla, eggs, lemon zest, and white sugar. Whisk together until combined and smooth.
2 eggs, 1 cup white sugar, 1/2 cup vegetable oil, 3/4 cup buttermilk*, zest of 1 lemon, 1 tbsp vanilla
Add in the dry ingredients and using a spatula, slowly fold until a soft muffin batter forms. Mix until JUST combined.
In the bowl with the fresh strawberries, add 1-2 tsps of flour and gently toss around until evenly coated. The light coating of flour will absorb any extra liquid it may have before adding it into the mixing bowl.
3/4 cup strawberries, 3/4 cup rhubarb
Add the strawberries and rhubarb and mix in a few times.
Evenly divide the batter between 12 muffin liners.
Sprinkle streusel evenly on top.
Bake the muffins at 375°F for 25-30 minutes. The muffins are ready when they bounce back at touch or a toothpick inserted comes out clean.
Notes
*To make buttermilk, stir 1 cup of milk with 1 tbsp of lemon juice or vinegar. Allow to sit on your counter for at least 10 minutes before using.
