Preheat your oven to 350F

Cream your egg, butter, mayonnaise, sugar, and vanilla together in a bowl until creamy.

Add in the baking powder, flour and salt and mix with a fork until the mixture is crumbly.

If the mixture is still crumbly, mix with your hands until the dough sticks together well.

Roll the dough out on a floured surface until the cookies are about 1/4" thick.

Use the cookie cutters to cut out the large cross cookies and place them on a cookie sheet lined with parchment paper.

Use the mini cross cookie cutter and cut out a mini cross from the large cross cookies.

Use a food processor to crush the jolly rancher candies one color at a time.

Use your fingers or a spoon to put in the crushed candies into the mini cross cavity.

Bake them at 350F for 6 minutes.

Then turn the pan and cook for an additional 3 minutes.

Allow them to cool on the pan for 5 minutes before moving them to a cooling rack to cool completely.
