or you could make them yourself
Hostess Twinkies
a bottle about the size of a Twinkie(a spice jar)
twelve 12 x 14 inch pieces of aluminum foil
pastry bag
toothpick
CAKE:
4 egg whites
One 16-ounce box golden pound cake mix
2/3 cup water
Nonstick spray
FILLING:
2 Tbsp butter
1/3 cup vegetable shortening
1 cup powdered sugar
1/4 cup granulated sugar
1/3 cup evaporated milk
1 tsp vanilla extract
2 drops lemon extract
Preheat oven to 325 degrees F. Fold each piece of foil in half twice. Wrap
the folded foil around the bottle to create a mold. Leave the top open for
pouring the batter in. Make twelve of these molds and arrange on a cookie
sheet. Spray the inside of each with nonstick spray.
Beat the egg whites until stiff. Combine with cake mix and water, and beat
about 2 minutes until thoroughly blended. Pour batter into molds, filling
each about 3/4 inch deep. Bake about 30 minutes, or until the cake is
golden brown and a toothpick comes out clean from the center.
For the filling, cream the butter and shortening. Slowly add the sugars
while beating. Add the evaporated milk, vanilla and lemon extracts. Mix on
medium speed until completely smooth and fluffy. When the cakes are done
and cooled, use a toothpick to make three small holes in the bottom of
each one. Move the toothpick around the inside of each cake to make room
for filling. Using the pastry bag, inject each cake with filling through all three holes.
