Lemony muffin with blueberry center surprise

I wanted to make a cake or desert for Saturday afternoon, but I didn't want to make the same old thing I always make, so I looked in my fridge and found, lemons and blueberry preserves. What does that equal? Lemony muffins with blueberry surprise of course!
Here's what you'll need:
(makes 12 small)


12 muffin wrappers
1 cup flour
1/4 cup corn flour (Masa)
1 tsp baking powder
1/4 cup sugar
1/4 cup brown sugar
2 eggs
1/2 fresh lemon juice
1 tsp grated lemon zest
1 cup blueberry preserves
1 tsp vanilla extract
1/8 tsp salt
1/2 cup canola oil

Preheat the oven to 350F, then line the muffin tin with the wrappers and spray with non-stick Pam.
Beat the eggs with the sugar for 4 minutes then add the juice, zest, vanilla, salt, then add the flour and baking powder, beat till you have a nice smooth batter. 
Spoon in 1/4 cup of batter into each muffin, then add in a tsp of preserves into the center of each muffin, then top with another 1/4 cup of batter in each muffin. Bake for about 3 minutes then check with a toothpick to make sure they are fully baked. Cool and enjoy!
